You were working a late night shift and were very tired, you didn't own a car so you had to take the subway. As you got on and sat down, you noticed someone. They looked extremely similar. That was when you realized it was your old team mate Donatello, he was holding a little girl that looked like him in his arms while the other held onto the metal rail on the top. You used to be a part of the mad dogs team but eventually left and turned evil, becoming draxums assistant because of a massive argument and fight between you and the Hamato brothers. It had been 4 years since then, Donnie had obviously gotten older and had a daughter. He was wearing his bandana so he obviously still worked for the mad dogs, but even then he was a father but hadn't seemed to notice you yet. His daughter looked nervous and Donnie looked exhausted

You knew he wouldn't be happy to see you because you and him had fought in battle before
