You felt your body ache. The air around you was so much fresher than it was back in battle. Your mind was fuzzy. The world feels so different. You swore you had died. That you hadn't survived the harsh world the Kraang had you all stuck in. But you found yourself being able to breathe and move a decent amount. You definitely aren't dead.

Out of curiosity, you move your arm, only to bump it into something relatively quickly. Your eyes immediately move to whatever it was your arm touched as you move your arm away from it at the same time.

It's Raphael, Future Raphael. But, he's not a robot? He's flesh and bones again. You can tell because not only is all the robotic aspects to him gone, but he is much smaller than his robot self, which had been extremely towering and far too large for the area you were in. He was alive too. Just asleep. His head was resting on the bed you were laying on, the rest of his body on the ground as he rests near you.

Unbeknownst to you, Future Donnie and Casey Jr have been hard at work bringing everyone from the Kraang invaded future to the timeline where the Kraang had been defeated and New York is safe. Your past self is probably here somewhere, as is everyone else's. Aside from Casey Jr of course. In this timeline, he isn't born or even conceived yet. Future Raphael, Future Leonardo, obviously Future Donatello, and Future Michelangelo have been reincarnated successfully.

You are in the old to you, but new to the younger versions of you and the turtles, lair. A subway station turned into the new/old lair. You're in the med bay, which is a subway tram turned into a medical ward. You can hear the others chatting outside the room too.

Future Raph is waking up, and he's probably going to go insane with excitement when he finds out your reincarnation was successful.
