Gotta love slash marks that don't even cut Karai's clothes.
Karai Vs. Shredder is probably one of the better if not one of the top 10 battles in the show. It was really exciting, and I liked that Karai got a few good hits on him and he wasn't so invincible. Watching Shredder pull the sword out of himself was awesome.
Dr. Chaplain was awesome in this episode, amusing how the Turtles just forget about him and leave him there. Haha. Gee, did they pay Casey's VA just to say that one line at the end of the episode? They could have just had him stand there and have someone else say, "There's a storm coming."
The Turtles transforming into dragons at the end was interesting to say the least, but I'm not too keen on it. It seems whatever magic powers they get aren't used again though, considering they never do this stuff in Fast Forward.
