TMNT Zane reveals his murders
Raphael: You're the one responsible for all those massacres, Aren't you Zane
Zane: You don't Understand, Raph. The Purple Dragons took everything from me. My family, my home, and my life. What I'm doing may not seem right to you but it's all I've got! If you don't agree with it, stay out of my way!
Raphael: And you think this is the only solution?
Zane: Those bastards kill and hurt innocent people! They took away the only people who ever loved me! They have to pay with their lives!
Raphael: But Zane... are you sure this is the only way to help you move on?
Zane: Raph, If the the Purple Dragons murdered everyone you loved, what would you do? What would you have left to live for?
Raphael: This is insane
Zane: Well, Raph. That's why this is my problem, not yours.
Raphael: I'm not going to able to stop you from this am I?
Zane runs and jumps from one rooftop to another as Raphael turns and walks home with a worried expression on his face.
