S1·E7 Call From The Abyss

Oz manages to shock Raven back to himself, and his gun fires, but at Zwei instead of Oz. Oz follows Raven, who claims that he is no longer the Gilbert Oz once knew, to the place where they found the pocket watch. Oz convinces Gil that he won't let him go even if he's joined the Nightray house (an enemy of Bezarius). Oz goes back for Alice, and on the way to the grave they catch a glimpse of one of Alice's memories, and are drawn into a dream dimension where they are confronted by the Will of the Abyss, who appears in the form of a stuffed rabbit. Gilbert shoots the rabbit and they escape.
