I'm actually also waiting for a good way to jump in with Blake. Fudo's being held on to and kept from posts until they arrive at the fire nation, so he can have his little episode of being consumed by his strength; perhaps something like an evil spirit possessing him while he's weakened from trying to control his own strength; and him pretty much go berserk n' try to kill the avatar or something.
