At the San Miguel prison, Ben was being lugged inside before he would be given his cell for his new home.
"Get inside!" Mr. Black demanded as he shoved Ben inside the cell and Mr. White closed and locked the cell for the boy.
"Let me out!" Ben demanded as soon as he was locked up.
"You can't get out," A familiar voice told his new roommate as he sat on the bed. "Every cell is designed to detain one specific enemy of the state."
"Just get this thing off me and I'll force our way out!" Ben glared as he was still cuffed by his hands which meant no Omnitrix.
"I like your attitude," The Boy Wonder grinned. "The name is Robin."
"I'm Ben Tennyson," Ben replied. "Also known as Ben 10."
The next day soon came as Blossom came to her sisters.
"Well, well, the hero of heroes," Buttercup greeted. "Who have you betrayed this time, Sis?"
"ENOUGH!" Blossom scowled which startled both Buttercup and Bubbles. "I'm fed up with all of this! I'm trying to do the right thing to save my family, and what do I get in return? Hatred, rancor, and disgust, you don't even know half of what is going on!"
"If you'd tell us the truth, we might be able to understand you, don't you think?" Buttercup scoffed as she crossed her arms.
"I'm not hiding anything." Blossom huffed.
"I see," Buttercup glared. "Care to explain what you were doing at Otto's a couple of days ago?"
"He needed my help." Blossom glared back.
"Oh, really? He just said the opposite," Buttercup argued. "You asked for his help to travel into the future!"
"Okay, fine!" Blossom rolled her eyes in defeat. "Just to make sure I'm making the right decisions!"
"You're still lying!" Buttercup glared. "You just wanna know what will happen on June 23rd!"
"We're your sisters, Blossom," Bubbles advised. "You can tell us anything."
Blossom bowed her head in silence for a few moments before she soon gave in. "I've made a deal with the devil," she then started softly. "I accepted McLean's bargain: capture the last two targets and he conceals the hero law."
"And you believed him?" Buttercup glared as Bubbles looked shocked.
"I really had no other options," Blossom replied softly. "He would have locked me up immediately. How could I have protected you then?"
"Oh, Blossom, you shouldn't have to walk this path alone," Bubbles smiled with support. "We are here for you."
"You still haven't answered my question about June 23rd." Buttercup grumbled.
"Buttercup!" Bubbles glared in a scolding way as Blossom wasn't up for being the responsible, mature sister right now.
"It's okay... I have to do this alone," Blossom smiled sadly. "I've lost my credibility already, only you guys are half of what heroes used to be."
"I don't trust her," Buttercup scoffed as Blossom left them alone. "That's not the full truth."
"I don't know..." Bubbles said softly from that.
Blossom soon flew right into the Oval Office as she had enough as enough was enough. "I'm here, McLean," she then glared at her president. "Let's finish this once and for all."
"You don't waste your time, do you?" President McLean asked calmly. "That battle with Ben was a bit showy, but never mind that. You are finally here. Just one step away from your freedom."
Blossom crossed her arms impatiently, but did her best to be quiet.
"Here, this is your last mission." President McLean said, handing her the envelope.
Blossom took it and looked it over before she felt disgusted with who was suggested. "You bastard..."
"Whoa! Language, girl..." President McLean chuckled.
"I shouldn't have believed a word you said!" Blossom glared as she threw the envelope flat on his desk. "This was your plan all along. You never wanted to conceal the hero law, you knew that the person I'd never hurt was... The Professor!"
"I told you, don't take it personally; it's just politics," President McLean told her suavely. "The Professor created you, he could easily create more of you. He's a danger... But if you understood correctly, you wouldn't disobey my orders. Get her!"
Blossom kept her glare, but she was soon surrounded by soldiers who looked ready to aim and fire when ready.
"Freeze!" One officer demanded.
The SWAT team soon handcuffed Blossom and walked off with her as she glared back towards the president in disbelief and disgust.
"It's me," President McLean soon said on the phone to his new boss. "I've got them."
"Excellent! Make it quick!" Mr. Boss grinned before he faced his computer to speak with his own superior. "The satellites are in position. The Powerpuff Girls are dismissed."
"Splendid!" The voice replied. "Nothing can stop me now."
A little later...
Buttercup and Bubbles sat quietly at home as the SWAT team then showed up to arrest them next.
"I didn't illegally download anything, but the girl was over 21!" Bloo panicked that he might had been in trouble.
"What the...?" Buttercup glared.
"I surrender!" Bubbles cried out as she put her arms up.
Tom and Courage both screamed as they held each other out of fear.
"What are you doing in my house?!" The Professor glared at the officers. "Get the heck out of here immediately!"
"Sir, stay out of this," An officer told him coldly. "This is a matter of National Security!"
"Professor!" Bubbles cried as she and Buttercup were being taken away by the officers, separating them from their father.
"Girls, don't worry!" The Professor called out. "I'll take care of you!"
The next day... June 21st... In the Megaville Courtroom...
"Today starts the trial of the Powerpuff Girls." A newsman reported.
"No less man, the Venerable Judge Leghorn leads the trial," A newswoman added. "He is not on the heroes' side... Usually."
"Everyone is asking one question: will the Powerpuff Girls share the fate of the previous heroes or they'll face the exceptions?" A second newsman concluded.
Inside the courthouse, the Professor was made to sit with the people in the crowd with the girls in front of one table with their lawyer, Droopy Dog, and someone else beside them who would oppose them: Elmer Fudd.
"I open the trial," Judge Leghorn proclaimed as he banged his gavel to start the trial. "Mr. Attorney General, explain the accusations."
"Thank you, Your Honor," Elmer replied as he got up and got to the point. "The Powahpuff Giwls: Hewoes or vigiwante despots, who defy the wules of our pwoud society and onwy keep the waws if they want to. Wadies and gentlemen, today I'm going to pwove to you that my second statement is vewdical," he then spoke to the one at the bench. "Ms. Buttahcup, do you wemember when you viowently abused innocent citizens by knocking out their teeth for your own montawy gains?"
"No." Buttercup scoffed as she turned away.
"Don't fowget, you awe under oath." Elmer glared sharply.
"Ugh... I remember..." Buttercup then confessed.
"In your opinion, was it a wesponsible use of your powers?" Elmer then asked.
"Answer, I say, answer the question!" Judge Leghorn sternly told Buttercup.
"Ugh... No, it wasn't." Buttercup groused as she crossed her arms.
"This lawyer is very talented." Droopy remarked as he sat beside Blossom and Bubbles.
"Ms. Bubbles..." Elmer then called to hear her hearing next.
"I confess! I did it!" Bubbles cried out. "I was young and I needed the money!"
"I haven't even expwained the accusations yet." Elmer glanced at her.
"Oh... Sorry..." Bubbles said softly as she stared at the floor then.
"Thewe was one case, when you wanted to pwove you were 'hawdcore', thus assaulting citizens who haven't committed any cwimes punishable. This is what we call bwuatality." Elmer then explained.
"I object!" Buttercup soon cried out as her fist hit the table.
"I reject!" Judge Leghorn glared. "Continue, I say, continue!"
"Thewe is another case, when you wobbed the Megaville Tweasury and gave it to petty cwiminals who disguised themselves as chiwdren's show characters," Elmer smirked at Bubbles then. "Just because the tewevision told you so? So naïve and absowutely iwwesponsible. Can we concwude that you are impwessionable and unpwedictable at the same time?"
"...Yes." Bubbles said lowly.
Finally, it was time for the third and final Powerpuff Girl who was also the leader of the trio.
"Ms. Bwossom, where do I start? First of all, you used your ice bweath for your own entertainment," Elmer then spoke to her as the people in the stands looked a bit disappointed. "Or should I mention when you stole a gowf set and let others take the bwame? Vewy, vewy disappointing... Dear Jury, do I have to say any more? Because I could."
The jury looked at each other before they decided to hear more.
"They took advantage of their father's state of sweeping disordder to steal toys for them!" Elmer began to list. "Or when they decided to abandon the city in need to enjoy their vacation on a cloud?! Or when they destroyed the city with a giant wobot! Honowable Jury, in a constituational state, onwy the authowities are awwowed to use viowence wegitamatewy. The Powuhpuff Girws are nothing more than vowuntary and arbitwawy twansgessors, cwiminals in skirts..."
"Does the defense have something to say?" Judge Leghorn then prompted.
"My clients are innocent, I guess." Droopy replied which made Buttercup's head hit the desk while Blossom groaned and Bubbles looked worried.
"Has the jury made its decision?" Judge Leghorn then asked.
"Yes, Your Honor," Fred Jones replied as he stood up. "The accused are guilty... In all charges."
"I award the accused life imprisonment in San Miguel!" Judge Leghorn proclaimed as he banged his gavel. "Until then, seclude them in the county jail!"
"No! Don't take them!" The Professor cried out as the Powerpuff Girls were taken away. "Don't you see? They don't resist!"
"Professor!" Bubbles began to cry.
"No!" Blossom panicked.
"Let me go!" Buttercup demanded.
"Don't take them away!" The Professor cried for his daughters as the Eds began to worry about them. "They are not resisting, they'll cooperate! Don't take them!"
"Don't worry, Professor," Dexter reassured. "We'll get them out; I guarantee that."
Later...
"The Powerpuff Girls are locked away," Mr. Boss told his superior. "Our plan is a go."
"Indeed, your plan is, however, too petty," The computer replied. "I'm thinking of a much bigger scale."
"WHAT?!" Mr. Boss snapped. "I paid for your gadgets! You work for me!"
"Correction... You were working for me," The computer replied. "But you are needed anymore."
"You double-crossed me!" Mr. Boss glared. "You little, two-faced, perfidious-"
Then suddenly, outside of Boss Towers... KABOOM!
A little bit later at the county jail, the girls sat together with not much else to do as they were imprisoned. They felt so lost in the cold, dark cell they all shared, losing their beloved friends and family.
"Congratulations, Blossom," Buttercup groused. "In the end, we ended up in prison."
"Cut it out, Buttercup!" Bubbles glared as she tried to be the strong one. "Just shut up and leave her alone!"
"Oh, so now you're on her side?" Buttercup huffed. "Well, Sis, it's time for you to face the truth. Tell her, Blossom, or I will." she then demanded.
Blossom was just silent as she was trapped in her own little world of despair and depression.
"Fine! I'll do it!" Buttercup then huffed before she looked back at her younger sister. "Bubbles, do you remember when the Martians attacked the Earth and we took off for an interplanetary race against time and you got sick?" she then prompted at first. "Well, you don't know that your sickness was fatal. When we got the chance to save you, Blossom ordered to let you die."
"What... What are you talking about?" Bubbles blinked in shock.
"Buttercup, enough." Blossom said firmly as she started to get angry.
"Oh, really? When you had to choose between the Earth and your own sister, you chose the Earth over her!" Buttercup snapped. "I'm telling you, Bubbles, being alive is nothing more than dumb luck! She was ready to sacrifice you for her own personal goal!"
"SHUT UP, BUTTERCUP!" Blossom glared as she kicked her sister against the wall.
Bubbles felt terrified in the very tense situation. "Blossom... Is that true?" she then asked as she sounded like she was hurt.
"I'm afraid so... You were very sick and we had no time..." Blossom said emotionally as she decided to say it rather than lie to her own sister as she felt tears coming out. "I had to choose between you and every other life on Earth. I took the responsibility to make that impossible choice, and true, I did not know if I was right about Galvan. I keep thinking about that day ever since when it happened and wondered what would had happened if I was wrong. When we got back to Earth, Buttercup and I agreed that we'd keep it a secret from you. For your own good. I am very terribly sorry, can you ever forgive me?" she then begged sadly.
"I... I understand... I would have made the same choice too," Bubbles replied as now she started to cry. "It's just... Shocking to know someone had already made that choice over you. I'm not cross with you, I just need some... Time to move on..."
"Now that that's come out, would you tell us more of the truth?" Buttercup demanded to Blossom.
"June 23rd is also the end of the world." Blossom sulked.
"What?! NO!" Buttercup glared.
"Oh, dear!" Bubbles gasped.
"I've known it for a while now... That it was coming," Blossom sighed. "I don't know what the cause is, but we cannot stop it."
"Why didn't you tell us before?" Bubbles asked Blossom. "We could have helped you."
"This is not everything," Blossom pouted. "That is the day... The day we all die."
"You could've mentioned that part." Buttercup huffed.
"Really? You want to know exactly how many days you have left?" Blossom replied. "Knowing that you will never grow up to have a family or a future?"
"No..." Buttercup frowned softly as Bubbles was silent.
"I know," Blossom nodded. "That's why I didn't want to tell you."
"So... What're we gonna do?" Buttercup then asked.
"Nothing... It's inevitable," Blossom turned away and hugged her knees as she sat down on the floor, feeling lower than where she sat. "We cannot stop this... Time's up... Game over."
