Even better, Aribeth!  Right now, you've set up a situation between you and Serana.  You've got the leader.  You don't even need to roll for this.<br/><br/>You can get a knife to her throat and keep her captive right now, kill her, whatever as long as you put her into a position that she can't react!  So like, if you lick the back of her head, that's gonna happen definitely, but then she'll react. Get a knife to her throat and you've got her held.
