Chapter 8: The Will of the Abyss (in the form of a white rabbit) captures Alice and starts demanding that Oz love her instead of Alice. Oz cuts her rant short, says he loves Alice, and shoots her in the head. For some reason, the anime version of this scene had Gil shoot her instead.
In chapter 55, things are looking pretty badly. Random people are dying left and right, Reim is dead, Alice and Leo have been kidnapped, and Break is going to pull one last ditch effort to try to take out two Baskervilles, knowing it will kill him. No one will be helping him, he specifically TOLD those who might have the opportunity not to, and he has absolutely no hope for survival. Then Gilbert shows up out of now where, and we finally get to see the Raven in all it's gruesome glory.
And when the terrified Baskerville's ask who the heck he is? His response is "This idiot(Break)'s left eye!"
And later, Reim appears out of nowhere to stop Lily from killing Break. Turns out his chain's power was "False Death". Hey, when you can't fight, you have to do what you can to be awesome. And he certainly delivered.
