Disclaimer: I do not own 2012 tmnt or 2003 tmnt. Also I'll refer to 2k3 Don (who is in 2k12 Don's body) as Don and 2k12 Don (who is in 2k3 Don's body) as Donnie. If you're still confused let me know. Also if you want me to make versions with the other turtles, please tell me.

"Father, can we talk about Don?" Leo asked as he entered Splinter's room. Splinter waved his hand as a gesture for Leo to join him.

"Of course Leonardo. I am worried about him as well. He is not quite himself. I sense something in him that I can't explain." Master Splinter said. Leo nodded.

"I sense it too Master Splinter. What do you think is wrong with him? Do you think it's even Don?" Leo asked. The old rat sensei put a hand on Leo's shoulder.

"Trust your instincts Leonardo. If you doubt your instincts, you will always be wrong." He said.

"Right sensei. Then we'll talk to him once he's calmed down. I can't believe I have to say that about Don. I guess there really is a first for everything." Leo then said.

"Come on! You have to have something in here that could help bring me home." Donnie said as he looked through Don's computer files.

Donnie had to admit, his counterpart had a lot of impressive inventions. Some of it almost seemed futuristic in a way. It was hard to believe that it was mostly made out of junk. Donnie then sat back and let out a deep breath. He was just so frustrated. Frustrated that this happened, that he didn't know why, that he didn't know anything about this world, that he once again lost a fight and with a different Raph, and most of all he had no idea how to get home!

Then he heard something that completely changed his mood. "Hey guys! We brought some pizza." He heard April's voice say. April came over! Oh he had to go see this world's April! Maybe getting to know this April would help him with his own April. So at that thought, Donnie jumped out of the chair and bolted to the main area of the lair.

"April!" Donnie said in excitement as he saw April. Then his expression changed slightly as he saw this world's Casey. "And Casey of course." He added.

"I hope you weren't working too hard, like you usually do. We brought a snack for you guys." April said. Everyone else also came out at the sound of April's voice.

"With you guys, four different pizzas really is just a snack." Casey joked as he put down the pizzas. Mikey immediately went over to it, licking his lips and eyeing it up.

"Hey knuckle-head! Don't just look at it drooling on yourself. Open one of dose bad boys up and let's eat!" Raph said as he rubbed his hands together.

"You don't have to tell me twice!" Mikey said as he grabbed a box and opened it up. He grabbed a slice and started eating it. Raph took the box from him and grabbed a couple slices of his own. Soon everyone was eating. Donnie made sure to claim a seat next to April as everyone made small talk.

This April was beautiful too. She was a lovely young lady and Donnie just couldn't keep his eyes off of her. He bet his April would become a lovely woman similar to this April. But then he had to snap out of his lovestruck state as April turned to him.

"So Don, are you working on anything new? You came from your lab when we showed up, so I'm guessing you're working on something. But then again, that brilliant mind of yours is always working on something." She asked. Donnie tried his hardest not blush.

"I-I... uh yes I a-am. It's uh really big and... um... important and complicated. But I'm sure you would be able to understand it. I mean, you're so smart for a female. No wait, that's not what I meant! I mean it was, but I didn't mean to phrase it that way. There's lots of intelligent females. And you're totally one of them. So what I'm trying to say it, just because you're pretty doesn't mean you're not smart. Wait, that doesn't sound right either. Let me start over!" Donnie rambled as he got more and more nervous.

"Alright, that's enough!" Leo said loudly and with much authority. Donnie immediately shut up and they all looked at Leo. Leo then stood up and locked eyes with Donnie.

"You have been acting not like yourself all day! I was going to talk to you later, but this just proved to me that you are not our Donatello." Leo accused. I was all quiet for a moment.

"Yeah. Don never rambles all nervously like that. Especially with April. He's not some nervous lovesick puppy." Mikey pointed out.

"And Don never gets upset over a little sparring match. Or calls anyone names. That's my thing." Raph brought up.

"What?" April asked. Raph waved her off with a, "Don't ask."

"Yeah, and Don doesn't glare at me like you've been doing. Don't think I didn't notice." Casey said to Donnie. Donnie was now sweating a little.

They all looked at Donnie, waiting for him to explain or say something. His dimensional brothers looked like they were ready to pounce him. Donnie had no idea what he should do. Telling the truth might cause them to attack him out of not believing. But then again, making up an excuse would cause them not to believe him and maybe even attack him as well. Donnie was officially trapped between and rock and hard place.

But then everyone looked over as they heard Splinter exit his room. The old rat walked over to the group and looked at Donnie. "You have an explanation you need to tell us. Do not fear for we will not harm you. Just tell us the truth." He said.

"Ok fine, I'll tell you." Donnie said, finally finding his voice again. Well not actually HIS voice per say, but you get the idea. "It's true that I'm not your Donnie. I'm a different Donatello. I'm from a completely different universe. And Somehow I woke up in this Donatello's body. It's like our consciousnesses have switched bodies. I don't know how or why it happened, but it did. And by Darwin's beard, I swear it's the truth." He finally admitted.

"Another universe? So the turtle mutiverse thing really is true! Awesome! I can't wait to learn all about this new world! Just like that time with those other turtles. So what am I like in your world? Totally awesome I bet." Mikey said all excited.

"Wait, what?" Donnie asked, now confused. It seems these turtles have encountered different universes before.
