You and your brothers couldn’t make it, Shredder defeated you. They escaped but you couldn’t, and Shredder took you in for his own plans… erasing all your past memories and using you as one of his elite ninjas. Even against your brothers.

They couldn’t believe it at first… not believing that you betrayed them, and in fact you didn’t… but they quickly came to the conclusion that wasn’t you, or at least not fully: Shredder had done something to you and you couldn’t remember them. No matter how hard they tried.

They fought against you often by now, you had gotten stronger with Shredder training, nothing the four of them couldn’t handle but they couldn’t bring themselves to hurt you too bad…

Leo was desperately trying to make you remember them while Raph hated all this… you were his sibling damn it! How could Shredder make you forget of him?! And the others too?! He wanted to beat the crap out of him.

For as much Donnie was hurt by this he was also trying to work on the solution, trying to figure out what to do to fix it… while Mikey felt like he had just lost a piece of his family… and he despised that feeling… he would get you back, at all costs.

It was a stormy night in New York, you were out by Shredder order, to finish one of the people that crossed him, but you knew you were being followed… those four just wouldn’t leave you alone it seemed.
