The elevator doors shut behind Chelsea as she continued to walk forward into the third test.

"I think I have figured out something about you, sparrow," GLaDOS said.

"Really?" Chelsea replied sarcastically. "What might that be?"

"I have realized that this entire time you have been going through stages of grief over what you inaccurately perceive to be a bad situation," GLaDOS said. "You, at first, were in a state of denial, then after spending some time in the anger phase, you began to bargain with me. After that, you started showing signs of being depressed. It was wonderful. I was sure that you would be in the acceptance phase by the time you had finished the tests, and we could put all this fighting behind us. But now, you seem to have regressed back into the anger phase. It's really very sad. We were making so much progress, and you were moving on towards acceptance at such a steady pace. It is a shame that we must go through these phases again. Going through them one time is hard enough. You must be quite the masochist to want to endure them again."

Chelsea said nothing, rolled her eyes, and walked up the stairs.

"It doesn't matter though," GLaDOS said. "We have the rest of your life to complete this process, and thankfully while your compliance is desired, it is not necessary now that I have found a good way to stop you."

"You are an idiot if you think that relying on that one method of restriction is going to stop me forever."

"I don't know. You do not seem to be able to break through the hard-light bridges. They seem very effective. It is quite funny if you think about it. The only thing that you can use to fight me is a weapon that I can use to restrain you. Your only weapon can be turned against you. It is very pathetic. Even your mother never had that problem. I guess that you are just not as resourceful as she was after all. You have nothing left to fight with."

"You're wrong about that, canary. I have more with me than you can ever imagine. The one with me is bigger than the one who is in this world and you," Chelsea replied as bravely as she could before she waled up the stairs and entered the room.

Chelsea had walked up the stairs and was entering the room.

Meanwhile, GLaDOS had another revelation about Chelsea. She realized that Chelsea could not be stopped because of her firm conviction in her religious beliefs, so if she was going to gain any further traction with her, those beliefs would have to be picked apart so that she doubted them completely.

Chelsea entered the room and saw a funnel emptying into a glass box with a grating bottom. The glass closed around the funnel so that entering the box was impossible. The rest of the room was covered in white moon rock walls. In the right corner of the room was a button while in the front left corner of the room was a pipe leaking the blue bouncing gel and in the back behind it was a pipe leaking water into a grating on the floor. It was obvious what needed to be done, but there was one problem.

Chelsea could see the cube was still in the funnel. She flew to the top of the box to get a closer look. As she hovered around the pipe, it was obvious that the funnel was not turned on. GLaDOS needed to turn it on and release the cube so that the test could begin. What was GLaDOS doing?

Chelsea took a deep breath and let herself relax. This inactivity meant one of two things. Either GLaDOS was planning something else, or she was currently distracted with something else. Either way, it was a welcome respite, and Chelsea wasn't worried. In the worst-case scenario, she would just have to spend her time cutting her way out of the testing chambers.

Chelsea landed on top of the box and walked towards the funnel. She wondered if she should simply cut the dumb thing open. Chelsea stopped right next to it and thought about what to do.

"My apologies," GLaDOS said suddenly. "It seems that the funnel is malfunctioning. I shall fix it for you."

"That's not necessary," Chelsea replied creating a disc in her left hand disappointed that her respite was over. "I can just break it open."

"You don't need to do that," GLaDOS said in annoyance. "I would prefer to be able to reuse at least some of my equipment after you finish testing. I only have a limited supply you know."

"What do you suggest we do then?" Chelsea asked as she dissolved the disc and crossed her arms.

"I suggest that you wait there until I fix the funnel if your limited attention span will allow you to," GLaDOS said. "That shouldn't be a problem. Should it? I think the dosage on your medicine is high enough to allow you to sit still for five minutes unless you need me to give you more."

"That won't be necessary," Chelsea said as she rubbed her left hand onto her tingling head.

Chelsea rubbed her head until the tingling subsided. Then she walked to the end of the box and sat down so that her feet were hanging over the edge.

In boredom, she fired an orange portal over on the ceiling and a blue portal directly beneath it. Chelsea then pushed herself over the edge of the box, landed on a disc that she created, and flew up to the orange portal. She immediately dissolved her disc and started falling downwards. Unfortunately, that was when GLaDOS moved the panels so that both portals vanished.

Chelsea just managed to create another disc for her feet to land on before she reached the floor.

"No more of that," GLaDOS said as she did it. "I would rather not have to clean up your vomit. Your blood will be disgusting enough."

Chelsea rolled her eyes and flew herself back up to the box. She laid down, crossed her arms behind her head, and thought about what to do next.

She could mess around with the bouncing gel, but she was afraid of it getting on her. Her mother told her what Cave Johnson had said about the gel being dangerous if she were to get herself covered in it. Chelsea continued to lie there and thought about what to do. It occurred to her that she could try to escape. She just had to figure out how.

"Seeing you lying there like that reminds me of something," GLaDOS said interrupting Chelsea's thoughts. "It reminds me of the first three and a half weeks of your stay here when you were just a helpless, little bird sleeping while we worked. It was interesting to see a human like that to be honest. You see whenever I worked with humans before they were bossy scientists, running and fighting like your mother, or unconscious in cryogenic chambers. Dealing with you was very different, because I had to expend a great deal of effort to keep you alive. You were so helpless. With all the drugs that were keeping you under, it was impossible for you to do anything for yourself. I had to do everything. I felt like a mother taking care of a baby or a nurse taking care of a patient in a hospital. It was an interesting chance to reflect on the feebleness of humans."

Both were silent for a moment. When GLaDOS did not hear Chelsea respond, she decided to continue talking.

"Dealing with you awake has been an interesting experience as well," GLaDOS said. "I have never dealt with anyone who was well…How should I put this…as convicted as you. It's quite amazing. You have stubbornly held on to everything you believe in circumstances when other people would question whether God even exists. How do you do it?"

"I'm used to dealing with crappy circumstances," Chelsea said. "I live in a world dominated by aliens. Dealing with this place is not enough to make me stop believing. Besides, having crappy circumstances does not mean God doesn't exist."

"Then, what do you blame the circumstances of your life on?" GLaDOS asked.

"Human error," Chelsea said. "It was Black Mesa who opened the portal to the Combines in the first place."

"I should have known," GLaDOS said. "Black Mesa is known for their stupidity. However, that is not the point. Here at Aperture, we have never claimed that there is no God. In fact, most of our employees admitted to belief in a supernatural deity of some sort…"

"Really?" Chelsea retorted sarcastically. "They could have fooled me."

"Anyways," GLaDOS said ignoring her previous comment. "The point is that we have always worked towards proving as many facts as we could, and I seek to continue that legacy by questioning the unknown. That leads me to my question. Why do you believe what you do?"

"You sure have a lot of respect for people you murdered. Don't you have something to fix?" Chelsea asked as she sat up starting to become very annoyed.

"I'm working on it, sparrow," GLaDOS said. "I just thought that we could talk while we waited. Now, why do you believe that there's a God?"

Chelsea decided to concede. She had to keep GLaDOS occupied anyway, so she might as well glorify God in the process.

She thought for a moment and said, "The world and the universe are crafted in such a way that would only make sense if there was a God."

"What do you mean?" GLaDOS asked. "How would the universe make less sense if there was no God?"

"The universe is so big and beautiful and possibly besides the Combines, we are the only creatures complex enough to enjoy it all," Chelsea said. "I don't think that was accidental. I think he made us with brains so that we would be able to wonder at all he has done. There is also the fact that the universe is not eternal. It began at some point, and he was responsible for it. The universe could not exist without him. Furthermore, there is also the fact that the earth and wherever the heck the Combines came from was a place in a perfect condition to support life. For a planet to achieve all those things perfectly out of pure chance is statistically impossible. Someone had to set it up so that that was possible. Those things wouldn't make as much sense if there was no God. Would they?"

"Fair enough," GLaDOS said. "But if there is a God, why doesn't he make himself known and stop all the other false religions?"

"He wants us to choose to love him," Chelsea said. "Love that is forced is not real love. He wants people to seek him out for themselves and know him personally. Besides that, good actions have meaning when people choose to do them. That is the purpose behind free will, but giving people free will also means giving them the ability to choose wrong. Also, the fact that we have religions at all proves that we have a desire to contact this God. Like C.S. Lewis said, if the desire exists, there must exist something to fulfill that desire. Right?"

"I suppose," GLaDOS said.

"Are we done?" Chelsea asked in annoyance.

"No," GLaDOS said. "I want to know more."

"No, you don't," Chelsea said sitting up. "I know that you couldn't care less, so why are you asking?"

"Perhaps, I do care," GLaDOS said. "Perhaps, I am a little bit curious. You are supposed to give an answer to anyone who asks you to give a reason for the hope that is in you. Aren't you?"

"Quoting the Bible doesn't suit you," Chelsea said standing up and staring at the camera.

"But I have a point. Do I not? You stand up for your faith so much. I just wanted to know why your hope is there to begin with. How do you know that you are not believing in nothing?" GLaDOS asked.

Chelsea sighed deeply. She was very annoyed. She normally would have loved getting a chance to show off her apologetics, but it wasn't as fun when she was talking to her warden.

GLaDOS was clearly looking for holes in her logic to torment her with. Chelsea knew that and did not want to give her the opportunity.

Unfortunately, she also knew that it was her duty to witness to others, so she had to do something. Even if it was not up to her to save GLaDOS, Chelsea could at least tell her what she knew. Couldn't she?

"Do you ever doubt your God?" GLaDOS asked.

"Of course, I do," Chelsea said.

"I thought that you were a Christian."

"I am, but that doesn't mean I don't doubt. I know as much as I do because I have doubted and have had to look up evidence for my beliefs. It's not a sin to have doubts you know. Habakkuk had doubts in the Bible, but God answered his questions and helped him believe again."

"Did he do that for you?"

"Yes, time after time I have discovered the same thing. I have something inside me that will not let God go. There is a hole inside me that he fills. Pascal mentioned it if you remember. Everyone has a longing for something supernatural inside them. That longing itself is a good amount of evidence in and of itself."

"Interesting," GLaDOS said trying to buy some time while she was thinking about what to say next.

Chelsea stood there for a moment in relieving silence. Sadly, it didn't last long. GLaDOS came back in again.

"How do you know that you can trust your own experiences?" GLaDOS asked coldly. "How do you know that everything that you have experienced is not just a delusion created by your own mind?"

"I'm not insane," Chelsea said calmly as she crossed her arms. "I have no reason to doubt what I've experienced any more than you would have any reason to doubt any of your internal experiences."

"But if your God is so real, why doesn't he make himself known to everybody in a big and physical way so that no one could ever have any doubts?"

"He did reveal himself. The people he talked to discuss their experiences in the Bible. He also sent Jesus, who is God as well you know. Now, he is invisible because he wants to attract the people who really love him. Forced love is not love at all. You should learn that."

GLaDOS had to research the through her database for other things to ask Chelsea about so she finally decided to "fix" the broken machine.

"Oh, look," GLaDOS said. "It is finally fixed. You may go on with the testing now."

Chelsea rolled her eyes and watched as the funnel finally dropped the cube into the box.

She ran, jumped off the box, and created a disc under herself to land on. Chelsea landed and flew the disc under the box, placed an orange portal, then flew to the blue bouncing gel, and placed a blue portal under the dripping pipe.

The gel went upwards into the box and covered the cube. The gel-covered cube bounced around and broke the glass cage it was in. The cube bounced out of the box, and Chelsea caught it with her portal gun. She flew over toward the water faucet, cleaned off the cube, and placed the cube onto the button causing the door to open.

"You see, GLaDOS," Chelsea said. "That was all that had to be done. Why did you have to drag out the process?"

"I'm not sure I know what you mean," GLaDOS said innocently.

"Sure," Chelsea said sarcastically.

Chelsea walked through the emancipation grid and into the elevator. The elevator started moving downwards once again.

"What is she getting at anyway?" Chelsea asked Jeffrey. "Why is she asking me all these questions?"

"Maybe, she's really curious," Jeffrey said.

"I can't afford to be that naïve, Jeff," Chelsea said cautiously. "She has to be up to something. She said that she was going to use these tests to tame me, so I take it that she is using this to manipulate me somehow. I can't believe she is sinking this low. Then again with her record, I can't say it's surprising."

"You did pretty well out there though," Jeffrey said. "I thought you answered pretty well."

Suddenly, the elevator stopped. Chelsea looked around. They were at the next testing chamber already. The ride was unusually short. Something about it did not feel right to her.

"That ride was too short," Chelsea said. "What is going on?"

Before Jeffrey could respond, the doors opened. GLaDOS curiously said nothing.

"Jeffrey," Chelsea whispered to him. "Talk to my parents and pray for me. Okay?"

"Will do," Jeffrey said.

Chelsea walked out and up the stairs.

GLaDOS said nothing. She did not give out one sarcastic comment.

The sign on the wall signaled that she was beginning the fourth test, so she entered the room. Chelsea was stupefied. There was nothing in the room except white panels, a red button on the floor, and a cube.

Chelsea looked up at the camera above the door incredulously.

"You are really insulting my intelligence now," Chelsea said. "What is this?"

GLaDOS again said nothing. Something wasn't right.

Chelsea used her portal gun to lift the cube and placed it on the button. The light came on, but the door did not open. Chelsea walked up to it to see if it was motion activated, but it did nothing.

It was then that she heard GLaDOS's gentle laughter.

"Not as easy as you thought," GLaDOS said. "Is it?"

"What are you playing at?" Chelsea asked. "What are you doing?"

"I thought that I would give you a seemingly simpler test so that you and I could talk more easily," GLaDOS said. "I will solve this test for you if you tell me all that I want to know, or you can try to solve it and leave the conversation for good if you succeed."

"You would solve the test for me?" Chelsea asked suspiciously. "You can't do that. Can you? Won't you get hurt or something?"

"No," GLaDOS said. "That only happens if I tell you how to solve the test. That is something I would never do. However, as I told you before, I can do whatever I want here, so I can just let you out if I want to."

"Why are you doing this?" Chelsea asked even more suspiciously. "What is it that you want to know?"

"I want to know why you believe what you do," GLaDOS said. "I want to know if what you believe is true. I want to know if you really understand it and are confident about it."

"Why?" Chelsea asked. "I don't understand. Why do you care?"

"I care because you care," GLaDOS said. "Think about it. Everything you believe is the foundation on which you build your entire life. It is the reason behind all you do. I want to be sure that you understand it completely. If not, I'm afraid that one day you may wake up and find that all your hope has been placed in a lie. I'm sure that you wouldn't want to deal with that."

"You're one to talk, hypocrite…" Chelsea said before she looked away and stopped herself realizing that she needed to control her emotions.

GLaDOS was trying to make her go insane and fall into despair. She was trying to break her, and Chelsea could not let that happen. She quickly asked God for strength.

"Is something the matter?" GLaDOS asked. "You look frightened."

"No," Chelsea said looking back toward the camera in determination. "Everything's fine. What do you want to know?"

"The Bible is accurate," GLaDOS said. "What the ancient scribes copied down is the book that you read now. It is accurate in that sense, but is it true in any other sense?"

Chelsea looked up and asked, "What do you mean?"

"Are the words really something that you can base your life on? You yourself seem to have trouble believing it."

"No, I don't."

"Yes, you do. Your many nervous breakdowns are a testament to that. If God was so good, wouldn't you never feel scared? He still allows bad things to happen to you. Since that is true, can you still trust him or anything in your faith? How do you know that it's not all meaningless?"

"I have faith. I can sense the supernatural. Everyone can if they use their spirit."

"Really?" GLaDOS said very skeptically. "Is the Bible really true then? If it wasn't, would your supernatural sense still exist?"

"No one would have any connection to God without the Bible," Chelsea said.

Chelsea started staring at the door and thinking of a way out. She knew that she would make a mistake eventually and did not want GLaDOS to take advantage of her when she did.

"How do you know that the Bible is true in its entirety?" GLaDOS asked. "How do you know that none of it is a lie?"

"It's historically accurate," Chelsea said. "Isn't it?"

"Yes," GLaDOS said. "For the most part, that has proven to be true archeologically, but do you really believe that God intervened in the lives of man to create Israel? How do you know that it's not just propaganda?"

"If it was propaganda, why would they talk about how they had failed?" Chelsea asked as she walked towards the wall. "The Jews chased after other gods and were repeatedly ravaged by other nations as punishment for their disloyalty. Propaganda is used to glorify a nation, not show their gross failures. Besides, it was written by a plethora of authors over thousands of years. They could not have all had that reason for writing it."

Chelsea put her hands on the door. It still didn't move. She was not sure of what to do so she allowed her portal device to drop to the floor, created two discs in her hands, and started trying to wedge the door open with them.

"Why do you think it was written then?" GLaDOS asked as she pulled a screen of hard light in front of the door.

Chelsea frowned, looked at the camera above the door, and said, "It was written to document God's relationship with mankind and his plan to redeem them."

Chelsea was determined. She kept trying to wedge open the door with her discs and find a way out. When that did not work, she created an additional disc under her and flew it as far back as she could go in the room. She was going to ram it open.

"Does that mean you believe all of the Bible then?" GLaDOS asked. "Including the part about creation?"

"Yes," Chelsea said.

Chelsea then flew towards the hard-light screen as fast as she could. She held her two discs in front of her. They were spinning as fast as they could. Chelsea accelerated until she reached the door. The hard-light discs stopped on the door and went no further. Chelsea could not cut hard light with hard light. She would have to think of something else.

Chelsea dissolved all the shields and sat down on the ground next to her portal gun.

"You believe that in spite of the theory of evolution," GLaDOS said.

"The two don't have to necessarily be mutually exclusive," Chelsea said as she continued to think. "God could have made the world through evolution. I don't think that's how it happened, but I think he could have used it. My parents and several other people in the church think so. The theory is just too far-fetched if you ask me though. I just don't see how all of life could have evolved from one organism. It just doesn't make sense. Not to mention the fact that it violates what God said about creation in the beginning philosophically. It was peaceful, and everyone lived in harmony. No one died or had to adapt to survive. That is why I don't agree with it. Microevolution makes sense, but macroevolution is just plain weird."

"How do you think the world came to be then?" GLaDOS asked.

"I believe in the creation story as it's told in the beginning of the Bible," Chelsea said calmly as she continued to think. "I think that the earth is younger than we think it is and was just made to look older. I also think that dinosaurs and humans lived at about the same time. I mean, where do you think all those legends of dragons came from? Every nation in the world has them, so they must have come from somewhere. However, I guess we won't know for sure until we die and can ask God. That is, until Christians die and can ask God, I'm not sure where you think you'll be spending eternity."

"Speaking of Christians," GLaDOS said. "Do you believe everything that the disciples wrote about Jesus was true? Jesus was a historical person, but can you prove that he was the Son of God?"

"His body disappeared, and the disciples were so convinced that he came back to life that they traveled across the world to tell everyone they could," Chelsea said. "Most of them never came back alive. Now tell me, who would die for something they knew was a lie?"

"I suppose nobody would," GLaDOS said.

Chelsea sighed and said, "How long is this going to go on?"

"How long is what going to go on?" GLaDOS asked.

"Your questions," Chelsea said in frustration. "I'm sick of answering them."

"Well, I'm not sick of asking them," GLaDOS said. "So, unless you find a way to leave, I'm going ask until I'm satisfied."

"When will you ever be satisfied?"

"Is that an honest question or are you being philosophical?"

"You're impossible."

Chelsea walked towards the portal gun on the ground and sat down next to it. Her head started tingling again. She held her right hand on the ground and started rubbing her neck with her left hand to make it stop. The sensation frightened her. Chelsea breathed deeply to calm down.

"God," she prayed in her mind. "Make it stop."

Chelsea laid on her back and massaged her scalp with her hands.

"Well," GLaDOS said. "Since you aren't solving the test, I might as well ask you another question."

Chelsea rolled her eyes in response.

"How do you feel about all the killing that went on in the Bible, especially all the killing that the Israelites did when they moved into Israel after leaving Egypt?" GLaDOS asked.

Chelsea rolled over on her right side so that she was facing away from the camera while she waited for the tingling the stop.

"Do you not know the answer or are you just trying to ignore me?" GLaDOS asked.

"Quit being such a troll," Chelsea retorted.

"Are you not going to answer?" GLaDOS asked.

After a deep breath, Chelsea sat up. She knew that she was not going to avoid her questions. If she tried to, GLaDOS would assume a victory in her favor. Chelsea could not allow that to happen. It was against her principles. As the tingling subsided, she thought for a moment before coming up with a response.

"Well?" GLaDOS asked impatiently.

"Do you believe that some evils are necessary in order to prevent a greater evil?" Chelsea said.

"What do you mean?" GLaDOS asked.

"I think that God told the Israelites to kill the people they did because they would have killed them if they didn't," Chelsea said. "It was a sad thing to have to do, but it was necessary for the future of Israel, so God ordained it."

"I have never heard anyone explain it like that," GLaDOS said. "That's interesting. I too believe in the idea of necessary evils."

"The evils that this place committed were not necessary," Chelsea said quickly. "They were wrong and unnecessary."

"That's hypocritical of you," GLaDOS said. "You believe that we were wrong in what we did but you believe that the Israelites were right in taking all the lives that they did?"

"God told the Israelites to act," Chelsea said. "These actions weren't meant to be followed in all circumstances by everybody. What Aperture did was wrong, and God never told them to act in the way that they did. Your blood is on your own hands."

"Alright," GLaDOS said coldly. "How about this then? What do you think about homosexuality?"

Chelsea looked straight at the camera, stood up, and picked up the portal gun.

"What do you think I'm going to say to that?" Chelsea asked. "I believe in the Bible, and I am a Christian."

"Well," GLaDOS said as Chelsea looked forward contemplating what her next move was going to be.

"It's a sin," Chelsea said as she fired an orange portal on the ceiling and a blue portal on the ground.

She ran, jumped through the portals, and fell very quickly. After falling for about a minute, she fired an orange portal onto the wall behind her. As she fell through it, she created a disc on her feet and with the added momentum from falling, she flew quickly towards the door and created a spinning disc with her left hand.

Chelsea was hoping that the increased speed would give her disc the momentum it needed to break through the hard light. Unfortunately, that was not the case. As soon as Chelsea reached the door, her discs stopped just like before. She dissolved the discs and sat on the ground grimacing in frustration.

"What do you mean by saying that it's a sin?" GLaDOS said. "Aren't people entitled to love whoever they want?"

Chelsea sighed. Having to explain the Christian stance on the issue was something that Chelsea was never alright with doing. She had to do it every time someone new came in. It was never fun.

"No," Chelsea said to answer GLaDOS's question. "In the beginning, God meant for us to love and be a certain way in our romantic relationships. In the Bible, he considers any deviation from that standard including homosexuality an act of rebellion and thus a sin. As for why people have homosexual desires, in Romans 1, it says that God allowed people to be inflamed with desire for their own sex because of mankind's rebellion, as a sort of curse."

"That's a harsh way of looking at it," GLaDOS said. "No wonder the church has always been seen as intolerant towards people."

"We're not intolerant," Chelsea said defensively. "We just don't like the sin, but that is no reason to hate the sinner."

"I'm curious," GLaDOS said. "Do you have any homosexuals in your congregation?"

"There are several people who live with us," Chelsea said. "They mostly live with us and attend services every now and again, but we tolerate each other. Only one guy has given it up completely. I guess it was easier for him since he's bi."

"Did you pressure him out of it?"

"No, he chose it for himself. He originally came to us with his partner. We let them stay with us and eventually the guy decided to start attending church services. When his partner found out, that guy was so pissed that he left us. Now, the guy who stayed has converted, is married to a woman, and is happy with his life. He says that he would rather not be with anyone else. People cannot choose what they deal with in this life, but they can choose how to respond to it and whether or not it defines them."

"I'm curious about something else as well. Was gay marriage legalized in your time?"

"Yes," Chelsea said as she got up, turned, and looked at the door once again.

"Was your church against it before it was legalized?" GLaDOS asked. "I'll bet it was. The church has always been against doing things differently. They were even against integration."

"Those people weren't really Christians then. There's nothing wrong with integration. God told us to love all types of people. Clearly, I'm not against it. In fact, let me tell you something interesting. Most people in my church are black."

"Really?"

"Yes, Pastor Roberts founded his church in an inner-city neighborhood in Detroit so demographically there were mostly African-Americans."

This whole conversation was not going according to GLaDOS's plan so far, but she had other things that she could question Chelsea about. She was not worried. She had other ways to intimidate her. GLaDOS was silent for a moment as Chelsea stared at the door thinking about how to escape.

"Okay," GLaDOS began breaking Chelsea's concentration. "About your virginity…"

"Okay, no," Chelsea said turning away to hide her embarrassment. "We are not going to discuss that!"

"I know it must be an embarrassing thing for you to mention. It is for most humans."

"Of course not! I don't need to justify it to you! Christians stay virgins until marriage, and that's all there is to it."

"I was just going to say…"

Chelsea mentally wracked her brain for any topic they could talk about. She quickly came up with something.

"Music!" Chelsea exclaimed as she walked into the center of the room so that the camera could see her. "I said on the test that I needed music so where is my music?"

"You do not get music," GLaDOS said coldly. "I test people without it."

"Come on! Put on some music. It helps me concentrate."

"That is what the drugs are for. I could give you some more if you are having trouble."

Chelsea crossed her arms, looked at the camera, and said, "Fine! If that's the way you are going to be, then I'll make my own music."

"Oh my God," GLaDOS said humoring her a little. "You cannot be serious. Are you going to sing?"

"I am," Chelsea said mischievously. "Why not? I have been told that I have a good singing voice."

"I know," GLaDOS said. "I heard it. Are you going to focus on the task at hand or do you have to be drugged some more?"

"Don't tell me not to live, Just sit and putter," Chelsea sang. "Life's candy and the sun's a ball of butter. Don't bring around a cloud to rain on my parade!"

Chelsea then jumped on a disc and flew into the center of the room.

She then continued to sing, "Don't tell me not to fly-I've simply got to. If someone takes a spill, it's me and not you. Who told you you're allowed to rain on my parade!?"

She flew in circles and sang, "I'll march my band out, I'll beat my drum, and if I'm fanned out, your turn at bat, sir. At least I didn't fake it. Hat, sir, I guess I didn't make it!"

Chelsea flew right in front of the camera and continued singing as GLaDOS watched completely dumbfounded.

"But whether I'm the rose of sheer perfection, or freckle on the nose of life's complexion, the cinder or the shiny apple of its eye," she sang.

Chelsea flew to the center of the room and dissolved the disc under her so that she fell to the floor as she began the line of lyric but caught herself on her newly created disc as she continued singing.

She was throwing a musical number to annoy GLaDOS, but she was also thinking. Doing stuff like this helped her mind get going so that she could focus on the problem at hand. It helped her power through the ADHD.

"I gotta fly once, I gotta try once, Only can die once, right, sir?" Chelsea sang. "Ooh, life is juicy, juicy, and you see I gotta have my bite, sir!"

Chelsea landed on the ground and decided to examine the door and button on the floor again.

"Get ready for me, love, cause I'm a comer," Chelsea sang. "I simply gotta march, my heart's a drummer. Don't bring around a cloud to rain on my parade!"

Suddenly, the light bulb flashed on in Chelsea's mind as she finally figured out how she was supposed to solve the test.

Chelsea turned around and walked back toward the button in rhythm while singing, "I'm gonna live and live now, get what I want-I know how, one roll for the whole she-bang, one throw, that bell will go clang…"

Chelsea then used the portal gun to pick up the cube.

"Eye on the target and wham," Chelsea sang as she created a disc under her and flew up towards the camera. "One shot, one gun shot, and BAM!"

When Chelsea sang the last word, she threw the cube towards the camera causing it to break.

GLaDOS quickly changed to the other camera in the room. She turned on the camera to see that Chelsea had figured out the puzzle.

The door was never locked in the first place, but by placing the cube on the button, Chelsea had locked the door. So, by removing the cube from the button, the door became unlocked again. She had figured it out. The test was a reverse test that GLaDOS had never tried out before.

"Hey, Mister Arnstein, here I am!" Chelsea sang as she triumphantly marched out the door.

"I'll march my band out," Chelsea sang as she marched to the elevator even more slowly than before. "I'll beat my drum, and if I'm fanned out, your turn at bat, sir, at least I didn't fake it. Hat, sir, I guess I didn't make it."

Chelsea created a disc under her, flew up into the air, and sang, "Get ready for me, love, 'cause I'm a comer, I simply gotta march, my heart's a drummer. Nobody, no, nobody is gonna rain on my parade!"

Chelsea stood there triumphantly with her hands in the air for a moment.

"Do you want applause?" GLaDOS said sarcastically.

"No," Chelsea said in satisfaction. "I was just basking in the moment."

"You are truly the oddest test subject that I have ever had," GLaDOS said. "I mean, what was the point of that?"

"A caged bird has a right to sing," Chelsea replied.

She then dissolved the disc under her, landed on the ground, and entered the elevator.

As the doors closed behind her and the elevator went down to the next test chamber, GLaDOS reflected on what she just saw and said, "Oh, God! What have I just unleashed?"
