Donatello sighed as he put the finishing touches on the last T-Phone for Slash and his team. As much as he wanted this mess to be over with, he couldn't help but feel some trepidation about trusting Slash. Slash was a stranger to them, and by all accounts, he probably shouldn't be trusted, especially if Robyn did get to him in some way. But Don knew that if he said anything of the sort to Raph, the hothead would defend Slash to the hilt. So Don tried his best to shake off these thoughts as he finished the last device.

You'll never get rid of me, Donnie. Stop trying.

Don shook his head. He'd been hearing Robyn's voice ever since the warehouse incident, though he hadn't told his brothers about it. He knew if he did, they would just say he was going crazy and needed help, so he kept it to himself as he often did. He knew it wasn't healthy to do that, but he couldn't think of another option.

A knock on his door startled him as he turned around. Leo was standing in the doorway.

"How's it going on the T-Phones, Donnie?" he asked his brother.

"Almost done, Leo," Don answered.

"Good. Then we'll meet up with Slash and meet his team, too."

"Leo, do you really think this is a good idea?" Don asked him.

"What do you mean?" Leo replied.

"I mean, Slash is a stranger. How do you know we can trust him?"

Leo sighed. "I don't trust him, Donnie, but Splinter's right. We need help, and if Slash and his team can help us, it's better for us to have them than to be without them. We're in over our heads on this one. Believe me, I don't like to admit that any more than you do, but it's the truth. We just have to go with it, okay? I already warned Raph that if Slash betrays us, all bets are off."

"I bet Raph didn't like that," Don muttered.

"No, he didn't, but he understands."

"Well, then I guess we'll have to make do with what we have. How long before we meet them?"

"A few hours."

"Okay, I should be done by then," Don said.

"Great. See you then."

You're so pathetic, Donnie. You know you can't beat me, not even with your stupid little allies who are so pathetic anyway. Just give up. You're in way over your head with this one.

"I won't give up," Don said quietly. "I can't give up." And with that last jab at the voice in his head, Don set out to continue his task. There was no way he was going to let Robyn win.

A few hours later, the Turtles were racing across the rooftops to meet with Slash. Don still felt some trepidation about all of this, but he had to trust Leo's judgment and Splinter's as well. They did need help, and there was no way they were going to be beaten by some crazy person. Raph pointed to where Slash waited, and they made their way over to them.

"Good to see you guys," Slash greeted them. "I thought maybe you were gonna hold out on me."

"We always keep our word, Slash," Leo said firmly, a hard glare in his eye.

"I can see that," Slash replied. "Let me lead you to our base."

The Turtles followed Slash to a group of warehouses. A pit formed in Don's stomach as he remembered the warehouse he and his brothers had encountered Robyn and Jason in. He only hoped the base wasn't in that one.

You can always back out now, Donnie. Just say the word and go home.

Don shook his head and ignored the voice as he focused on following Slash to his base. Thankfully, it wasn't in the same district where they had encountered Robyn and Jason, and Don felt some relief at that.

Slash opened the door and beckoned them inside. "It's not much of a home, but it's the best we could find for now."

The Turtles followed him into the warehouse and saw that it was a pretty big place filled with all the amenities of a home. Don was amazed at everything they'd been able to fit inside of it. Slash led them to where a group of mutants were congregated. Don's mouth dropped open as he recognized Slash's team. Mikey's eyes lit up, and he barreled toward a familiar form.

"Leatherhead!" he yelled as he embraced the mutant alligator. "I missed you, buddy! How did you get here?"

"I escaped Dimension X along with some of the Kraang who I defeated with the help of Slash and the others," Leatherhead replied. "Slash thought I would fit well within their team, and so I joined. It is good to see you, my friends."

Don wasn't so sure about that one since Leatherhead had constantly grabbed him by the face whenever he went into a rage. He only hoped no face grabbing would occur and decided to give the alligator a wide berth so as to prevent it. His attention was turned to another mutant he recognized.

"Doctor Rockwell?" he gasped.

"Yes, and you must be Donatello," Rockwell replied. "I remember our first encounter with that young lady friend of yours. I am very sorry for my behavior during that time. I was not myself, and I regret the beating I gave you."

"Uh, that's okay, Doc," said Don. "I forgive you."

Ha! Ha! Ha! You got beaten up by a monkey? How sad! You're worse than I thought, Donnie. You're so weak!

Once again, Don shook his head to rid himself of the voice. Why was he letting her win?

"Are you okay, Donnie?" Leo asked.

"I'm fine," Don answered. "Just a little headache."

"Hey, don't forget about me!" a voice squeaked as a mutant pigeon flew around the room.

"Pigeon Pete?" Raph asked, rolling his eyes. "What the hell are you doing here?"

"I'm part of the team," Pete replied.

"Yeah, but why?" Raph asked. "You're probably the worst mutant in the history of mutants."

"Hey, I've gotten a lot tougher since you saw me last," Pete said defensively.

"Pete's good at being a spy," Slash confirmed. "We've used him to gather intel on things that are going on in the city. Since he can fly, he can spot things some of us can't see."

"See? I'm useful," Pete bragged.

"Whatever," Raph said, rolling his eyes.

"So, where are the phones?" Slash asked.

"Right here," Don answered and presented them to the team. "They work the same way ours do, and we can contact each other if we need to."

"Great," Slash said. "If we see anything weird, we'll tell you right away."

"Sounds good," Leo confirmed. "Thanks for taking the time to help us, Slash. We really appreciate it."

"No problem. Hey, you guys wanna stay for a bit?"

"Can we, Leo?" Mikey begged.

"Sorry, Mikey, but we have practice in the morning," Leo answered. "But we'll stop by again soon, okay?"

Mikey sighed. "Okay," he said dejectedly.

The Turtles said goodbye to their new allies and headed for home. They were in better spirits, but Don couldn't help but feel that something was off about this.

"That definitely wasn't bad, was it, guys?" Raph asked.

"No, it wasn't," Leo agreed. "I really like the Mutanimals and think they'll be good allies for us."

"It's so cool Leatherhead's one of them," Mikey said happily. "I was afraid I'd lost him forever."

"Yeah, that's just great," Don said.

"Something wrong, D?" Mikey asked his brother.

"I just don't have a good feeling about this," Don said. "Who's to say that Robyn will show up? For all we know, she could be out of the state or even the country."

"I know, Donnie, but we have to keep all of our options open," Leo said. "Just calm down. I know we can do this, okay? You have to trust me."

"I do trust you, Leo. I just don't trust the situation."

Good man, Donnie. Get out now while you still can.

"Shut up," Don muttered.

"What did you say?" Raph asked him.

"What?"

"You said something," Raph said. "What's going on with you?"

"Nothing. I was just thinking about an experiment."

"It sounded like you told someone to shut up."

"I didn't say that, Raph. You must be imagining things."

Raph shrugged. "If you say so."

Ha! Even your brothers are starting to notice things. Better get out now before things really start hitting the fan.

Don ignored the voice even tough Robyn was right. If he wasn't careful, his brothers were going to start looking at him funny and questioning his sanity, and he couldn't have that. He followed his brothers home and went back into his lab to try and get his mind off of everything. After some time, he grew tired and decided it was time for bed. He looked at his phone, expecting a text, but nothing happened. But as he drifted off to sleep, he heard that annoying voice.

You'll never get rid of me, Donnie. I'm part of you and always will be. Deal with it, freak!

"I will get rid of you, Robyn, once and for all," Don stated. "I don't know how yet, but mark my words you won't be able to torment anyone ever again once I'm done with you. You will pay for everything you have ever done to me and my family."

And with that last vow, Don fell asleep and tried to remain positive about the outcome of what could happen. Robyn was still out there, but she wasn't going to haunt him any longer. He was going to get rid of her, even if it meant doing something drastic.

End of Part Two

A/N: And that's the end of this story. I'm so happy that I was able to finish this story once and for all as it has caused me a great deal of stress on how to end it. But now it has come, and I'm relieved. But though this is the end of the story, it isn't the end of the series. I have a third story I'm planning out though I haven't made much progress with it yet. But once I do, be sure to look for Game of Lies, coming soon. In the meantime, feel free to leave a review and have a shelltastic day.
