Question answering time!
1. His gender doesn't change, so 'he' would work just fine, but 'it/the wolf' also works well since, like you said, it isn't exactly him. Depending on what sort of POV it's in, I'd probably use a mix of 'he' (since his gender is known) and 'the wolf' (since he isn't in control) in place of his name, but that's just my style. Do whatever you think sounds best in the whole grand scheme of things!
2. Of course! I figured it would be shorter, since we're getting back into closer character interaction. I just had a lot to say last time still.
3. Whatever we want to do. What do you feel like? How long do we want to let Thea and Byrce duke it out before either Zane jumps in, or his episode wears out? Do you want him to attack her (that'd make more mental regret for your guy, if you felt like being that much more evil to him. xD), or for Zane to intervene and take the brunt of the attack?
Well, you're running out of time! I'd love to know if you decide on something! Mine's a sort of Raven Queen. But not.
