Teenage Mutant Ninja Turtles, Season 2

Leonardo:
(Narrating) There comes a time in the life a ninja when he or she must choose between the path that others would have them follow and the true path of their heart. Karai was raised by the Shredder, taught ninjutsu by the Shredder, and she serves the Shredder still. But there's something about Karai that's different. She's not like the Shredder and because of that, Karai is going to have to make a choice between serving the Shredder and serving her own sense of honor. I only hope she makes the right choice.
