[to his pet turtle Spike] I know you're a little worried about me. Look, I'm not gonna lie to you. We've never gone into a fight like this, and I don't know what's gonna happen. But you don't have to worry. I will make it back. I love you, man.
[Raph then turns around in shock to see Mikey, who has heard his every word.]
Failure is a possibility all leaders must face, Leonardo. It is something I had to face in Japan during my battle with my old enemy, the Shredder. Years ago, Oroku Saki, as Shredder was called then, had been my friend. But the love of a woman came between us. He could not accept it and his jealously turned outward in a vengeful attack. And although he could not defeat me that day, my world burned and crumbled around me, as the battle took the life of my beloved Tang Shen. And I lost my baby daughter, Miwa.
