The reason I didn't is that I'm starting to lose confidence with Monty and the Grimm. So much so that I'm starting to see Cinder as the main antagonist which would be sad because the Grimm has such promise.

I said it before, a character needs to die or get seriously injured by the Grimm. If not, then we need to see RWBY in a position of helplessness against them.

This is where Oobleck comes in. He either saves them or dies in the next 2 episode. If he survives, I guess Zwei could die but that would be a copout and wouldn't really solve the problem so I doubt that would happen.
