That would be a pretty stupid decision for her to make. I would understand if she left Lawrence because of embarrassment, but if she actually felt "betrayed," it would be simply foolish. Lawrence has been nothing but sincere with her, and she should know by now that even if Lawrence is smart, he is not smart (or evil) enough to manage all of the things she accuses him of. Numerous events simply prove otherwise.

Right now, I feel for Lawrence more. Holo has the right to be upset, but so does Lawrence, yet he can't even do so because of Holo's attacks. If he cared for Holo as much as I think he does, all of those words must have really hurt him. If she leaves him for that crappy kid for a dumb reason like "He won't betray me unlike Lawrence." (for god's sake, the kid doesn't even know she has wolf ears and a tail, or worse, her true form), that would really disappoint me.
