Yeah, that seems like the obvious conclusion. Although the obvious ones aren't always the correct ones in the end. Still, he should have had some solid reason to maintain such a distance from Oz. Unless he was actively preparing Oz to become a contractee, and was of the opinion a regular kid can't handle a chain. I would prefer a plot element like that a little bit more than the obvious one.

In any case, I'm getting a bit tired of Oz not succeeding in anything and simply aimlessly wandering around, without a bigger plan than grasp at anything loose he sees around, especially if it somehow mirrors his own oh-so-traumatic past. Their wanderings should anyway be about finding B-Rabbit's lost memories, not Oz's multiple mental traumas - unless those two are tightly connected, which might very well be the case, considering the earlier eps and the Will of the Abyss. But even in that case surely there would be better ways to do it than endlessly munch his loveless childhood issues.

Oh, well, if nothing else, at least B-Rabbit now seems to take Oz more seriously on many levels. That counts for something.
