I don't often give five stars, but when I do, I'l make sure that it is an awesome submission.
Also, who is the guy in the "lesson" part? One of the authors? Or is it a reference?
My only complaint comes from the car scene. The car itself could've been drawn better.
I also found quite a change of pace since episode 1. The first one had way more action. Not that I have something against less action, just thought that some more awesome action and some more perfectly characterized characters could've fit perfectly there.
