That day on Normandy, after saving Legion, Shepard has decided that it was the right time to use opportunity of having privacy so he invited Liara to his cabin. Liara accepted the invitation and used the elevator to get up. She entered the cabin and saw Shepard was taking down his shirt.

"Shepard."

"Liara?"

"I've heard what happened. He was lucky that he made it out alive."

"I know, Liara." Shepard said and Liara sat on the bed beside him, followed by putting her hand on Shepard's face.

"I can sense how tense you must feel now, Shepard."

"You can help me to ease the tension." Shepard smiled at her. Liara smiled back and then they kissed each other. The kiss started series of events. Shepard helped Liara to get undressed and Liara took Shepard's uniform pants off too. They lied naked on the bed and Shepard didn't lose eye contact with Liara. The journey across the galaxy became a dream for Adrian Shepard and Liara T'Soni as soon as they merged physically and mentally.

Back in medical bay, Legion's own hand was still intertwined with Daniel's hand. A skin of the human was finally getting a healthy color thanks to a blood transfusion. As Legion concentrated on face of the sleeping Daniel, he didn't notice that Dr. Chakwas was going to check on Daniel while Legion was satisfying of his need to hold Daniel's hand. Legion finally came to his senses and heard steps of Dr. Chakwas approaching them. He managed to disrupt the connection of hands but Chakwas noticed it.

"What was that?" Dr. Chakwas asked.

"We do not understand."

"Don't play that on me. I could see that you've been doing something to him." She said and Legion knew he will not get out of this. He had to find a reason so he started to speak.

"We were monitoring his pulse." He lied.

"Oh… really. I guess that is good. Though I thought you Geth wouldn't be showing concern about humans. Maybe Shepard was right about you."

"We wish to learn more about humans. That is why this platform decided to stay and monitor this human's processes." Legion explained, trying to cover the fact that he was just satisfying his urgent need to hold Daniel's hand. It was a strange way how this Geth would… masturbate? However, when he held the hand, he was feeling continuous waves of heat rushing through his body. It was pleasant and it was new. Legion didn't know why was he feeling things. He never used to experience something like feeling. It was in conflict with his protocol.

"I see… well, the monitor says his blood level is full. Everything should be fine now." Chakwas said and disconnected the pumping machine, patching Daniel's arm. Legion watched fascinated how Dr. Chakwas performed all medical stuff needed to prevent blood leak out of the arm. Then something was telling him he should already leave before he would say the truth. The Geth stood up.

"We must speak to other crew members." Legion said and left the medical bay. Doctor Chakwas didn't understand that but she rather ignored that and continued with the care about Daniel. Legion's next stop was at the cockpit. He wanted to talk to Joker.

"Jeff, it looks like you have a visit." EDI notified Joker who was turning around with his chair.

"Well, Liara. I thought you would be with Shepard but if you want some shoulder to cry on…" Joker smiled but then he saw Legion, "Oh… never mind. What's up, Legion? What would a Geth want from somebody like me?"

"We wished to speak with Shepard-commander but we cannot find him."

"Shepard is at his cabin, but if I were you, I wouldn't bother him right now. He's got some business with Liara if you know what I mean." Joker chuckled.

"Jeff, I don't think Legion knows that you mean sexual intercourse."

"We do not know since Geth are not in need of this. However, now that you mention it, we want to know what is the sexual intercourse." Legion said and Joker blushed slightly.

"Oh… well… it's uh… EDI? Can you help?"

"You're asking the space ship's AI which doesn't have organic instincts to answer what is sexual intercourse about… if you want explanation, Legion, it's act when organics can reproduce. Organics have their anatomy based on instincts and hormones which give them opportunity to 'want' this intercourse with another one."

"Yeah, pretty much. I think you don't have to worry about this, Legion. Like EDI said, it's mostly about instincts and hormones which make some organic to want this so it shouldn't bother you because you don't have hormones… at least I think so…" Joker said and his 'at least I think so' brought some doubts in Legion's processor. Doubts, another thing Legion was question that Geth would have.

"So… Shepard-commander is having sexual intercourse with Liara T'Soni now." Legion said and Joker nodded. Legion's curiosity was stronger and stronger. He wanted to know so he turned around and started walking away, "We wish to know more. We will visit Shepard-commander."

"W-W-Wait! Legion, no! That is private stuff!" Joker tried to explain but it seemed that Legion wasn't listening.

"It seems Legion didn't hear you, Jeff." EDI said and Joker face-palmed himself.

"Oh crap! Shepard will make the fire once Legion enters his cabin!" Joker rather went back to piloting the ship. Back in the cabin, Shepard and Liara were under blanket, Shepard with one hand under his head and the other one holding Liara who was leaned with her head to Shepard's chest. Both of them slightly resting, almost asleep after having a great sex. Suddenly, they heard shifting of the cabin door. Shepard abruptly opened his eyes and raised himself on elbows, seeing Legion entering the room.

"Shepard-commander." Legion said and Liara opened her eyes as well. She hid her breasts with the blanket.

"Legion! What the hell are you doing here?!"

"We wished to see sexual intercourse so we could learn about humans."

"Nobody enters my cabin without my permission! Legion, leave! Now!" Shepard shouted at Legion who walked backwards a little bit.

"We beg for apology, Shepard-commander. We did not mean to interfere to private stuff." Legion turned back and left the cabin. Shepard and Liara put the blanket down.

"Damn… Legion…"

"Shepard, did you hear what he was talking about?"

"Yes, I heard that. Maybe I should talk to him… I don't know what got into me that I started shouting at him."

"I guess it meant there was enough time for us."

"Liara?"

"I should get back to my work. I'll see you later." Liara said and put on her clothes. Once she was dressed up, she went to the elevator and waved Shepard. The door closed behind her and Shepard was alone now. He had to think of what he did to Legion and how he shouted at him. Shepard decided to discover what was happening so he dressed himself up as well and sat to his private terminal.

"EDI, tell Legion to come up here. He wanted to talk to me" Adrian said and went to sit back on his bed. After a while he saw as Legion entered his cabin for the second time. This time he wasn't going to yell at him.

"Don't you want to sit, Legion?"

"We do not need it."

"Alright… Legion, I know you might not care about it, but I am sorry for that I shouted at you before while."

"No offense taken, commander. We are not programmed to feel offended."

"Still, I want you to know that you are part of my crew. You just came in a bad time, that's all."

"We didn't know that sexual intercourse was private act, however, this platform wants to know more about humans."

"You still say that since you're on board of Normandy again, Legion. I thought that Geth weren't interested in organics."

"This platform wishes to understand."

"Understand? What do you mean?"

"Understand the concept of humanity. We want to know what are feelings?"

"Feelings?" Shepard asked and Legion nodded, "Well… feelings are something that organics have. They can be physical, like tactile feelings. You can feel pain, hot, cold, pressure… those are taken care by receptors."

"Receptors, yes. We have receptors as well, only their threshold is different."

"And then there are abstract feelings. Something you can't see or describe and I am not sure if I can explain it to you somehow that you could understand."

"Shepard-commander, we wish to understand this. Try to explain."

"Alright. So these abstract feelings are hard to describe because that is a matter of personality. Every individual is different, unique and all of us have specific angle of seeing things. These feelings are emotions. You may feel happy, sad, heartbroken, angry… everything but it depends on your personality. Some people are sensitive, they tend to feel things very intensively and some are inert, they have a lack of feelings… and they tend to be cruel to others."

"The Geth aren't individual. We are all part of one consensus."

"That's why it's hard for you to understand and for me to explain, Legion. Because organics have feelings, they are also afraid of being alone so they want to find somebody who will share their feelings mutually. This need of having somebody by your side is called love, Legion."

"Love…?"

"Yes, it's a strong feeling that cannot be understood, it's something what comes during the life. It makes you do strange things, even stupid things. Love doesn't make sense so please, don't ask me to explain."

"Does Shepard-commander love miss Liara T'Soni?" Legion asked and Shepard nodded, "So sexual intercourse is a result of love?" Shepard nodded once more, "Shepard-commander… can a simple holding of hand be taken as an act of sexual intercourse?"

"No, but it shows how dear that person is to you… Legion, why do you ask me all these things? It doesn't sound like you want to know only definitions. Is there anything I should know about?" Shepard said and Legion thought for a while.

"No data available." Legion said and left the cabin. Commander was confused.
