The black smoke soon disappears and Nikita emerges from within it. She looks down at her clothes: they've been replaced by an indestructible, black armor with spikes and the heartless symbol is over her chest. She's also able to emit dark smoke from her hands.

"What's happened to me?" Nikita asked. "The darkness in your heart has given you new powers, more than you ever knew." Evil Morty said. "So I'm one of the heartless now?" Nikita asked. "Better. Your anger and sadness have been building up inside you until you finally let it take over." Evil Morty said. "Now, you can do anything you want to with your new dark magic."

Nikita toyed around with her new powers a bit before she realized something: she could use these powers to get revenge on April! This was like a dream come true, she would finally make April pay for hurting her and the Turtles. After all, it made so much sense now, she needed to pay! She wanted April to feel the same kind of pain she caused them. And now with these new dark powers, Nikita would finally get her revenge.

"So you're telling me that I can use my newfound dark magic however I want, whenever I want to?" She asked. "Yes! You can use them to get whatever you want, like getting revenge on a certain teenage girl." Evil Morty said. "How soon do I start?" Nikita asked.

Meanwhile, April was walking down a sidewalk to visit Casey at the ice rink. She was hoping to hang out with him for awhile before going home to her aunt. She stopped and looked up at the buildings; she didn't see any sign of the Ninja Turtles. She signed with relief because she was still holding a grudge against them, but strangely not as much as she did before. While she was still mad at them for causing her dad's mutation, she started feeling some regret. Casey's words still stuck to her mind:

"No one can hold a grudge forever. I'm sure you and your friends will make up soon enough. It just takes time."

But April was doubtful over making amends with her former friends. She previously vowed to start over and lead a normal life. But maybe Casey has a point, maybe she overreacted over the whole situation. Maybe she should reconsider her decision and return to the sewers to make up with the Turtles. But April was doubtful that they would want her back in their lives again after the way she acted. She even started to believe that they might be mad at her and wouldn't want to reconcile. Especially Nikita; she was really upset and furious over what April said. So much so that she even ran after her and yelled at her face. Nikita's words also stuck to April's mind:

"Well we don't want you in OUR lives, either! You panty-waisted, red-haired bitch!"

April could still see the rage in Nikita's eyes and the complete sadness in Donatello's face. She started feeling guilty over her behavior as she realized how much she hurt them both. She couldn't even imagine how much pain she caused them or the extreme guilt she's putting them through. April tried to push those memories aside as she made her way inside the building. She saw Casey playing on the ice rink as she set her bag down on the benches. Casey was finishing his lone game when he saw April. He happily skied towards her and lifted up his mask.

"Hey, red! Did I miss a session today?" He asked. "No, I'm just here to hang out. That's all." April said.

Meanwhile, Nikita was making her way down the sewers to see the Turtles. She wore a black cloak to hide her new outfit because she didn't want her friends to see it. She didn't want them to freak out or anything because they were already stressed out over the whole mutagen incident. Ever since the outbreak, they've been trying to find all the mutagen canisters that have been spilled all over New York City. When he's not out hunting down the canisters with his brothers, Donatello is in his lab trying to find a cure for April's dad Kirby. Ever since that incident, Donatello has been trying to make a retro-mutagen to cure Kirby and return him back to normal. He believes that if he cures him, then April just might want to be friends again. Might. But Nikita was doubtful that April would want to return to them after that day. For all she knows, she still blames them for causing the accident in the first place.

"But they didn't mean to, it was an accident!" She thought to herself.

Once she made it towards their home, Nikita saw the Turtles taking a break from mutagen hunting. Michelangelo was in the kitchen making some kind of weird meal or something. Raphael was practicing some punching moves on a punching bag. And lastly, Leonardo was in the living room watching tv. Nikita took off her hood and walked towards them.

"Well. Looks like it happened again: the Princess left the team earlier, the team feels guilty for what happened." Leonardo said. "Just like usual." Michelangelo said. "But at the end of the episode, she always comes back." Donatello said. "Yeah, but let's face reality: April's gone for good. We'll probably never see her again." Raphael said, sadly.

This made Donatello even more upset than before.

"I'll...be in my lab." He said, sadly walking towards his lab.

Nikita felt sadness for the brothers, they really missed their friend April. Anger began to erupt inside of her. This was the final straw! Nikita took out her daggers and ran out of the lair. She's decided enough is enough and now she's going to do something about it. April was going to pay for all of the pain she caused them! She WILL pay for hurting Donatello and his brothers! Nikita ran past Splinter, who was staring back with a concerned look on his face.

Meanwhile, April and Casey were hanging out together in the ice rink. Casey was getting his gear ready to leave the building with his new friend April. He saw that April was feeling a little down and comforted her.

"Hey! Are you feeling okay, red?" He asked. "Oh! Yeah I'm...fine." April said. "Are you sure about that? You don't look fine." Casey said. "Well...the thing is. I've been thinking about what you said earlier, about me reconciling with my friends." April said.

Casey moved closer to April and leaned against the bar.

"Yeah? What about that?" He asked. "I was thinking that maybe you're right. Maybe I should go back to my friends and work things out." April said. "Great! I knew you couldn't hold a grudge for long." Casey said, smiling.

Suddenly, a loud explosion shook the building. April and Casey stood in shock over what happened. They stared at the huge hole where the entrance was. The dust started to clear out and Nikita stood in the middle of it.

"Hello, April. Happy to see me again?" She asked, looking forward to reconnecting with her former friend.
