You were a Kraang hybrid, just like April. You simply tried to life a normal life, especially after running away from Kraang.

She had met you during school, and found out that you were part Kraang as well, so she had the turtles help get you into the sewers.

After you were dragged into the sewers and tied to a chair, she went up to you "What happened to my mother?" She asked, wanting to learn something, trying to figure out her roman empire.
