nearly ganking Kevin's mom in the second ep. Had Benny been a reluctant werewolf, I'd have been OK with Dean letting Kate go. But I still think it conflicts with his new "pure hunter" status.
On a semi-related note, really looking forward to seeing Benny next week (on Halloween no less--eeee!). And I can't wait to see what happens when Sam finally meets Benny *and* knows what he is (I'm not really expecting that to happen in the same ep--this show loves having the bros keep secrets from each other).
