I saw your tags about Vane being an ambush hunter and I agree! Esp when an integral part of his ambush is setting Anne on someone.

See, the thing is that when he’s using that tactic, he has a habit of using himself as the bait. If Anne’s getting involved in something, that’s usually a sign that he’s not bothering with stealth. Look at the complete lack of subtlety on display in s1, vs when Vane is on his own, sans Jack and Anne. He becomes a lot more strategic when he doesn’t have them with him, because he knows he can’t afford to make mistakes the way he can with Jack and Anne to back him up.
