When Astarion tried to bite me, I staked him, and the other party members expressed relief. Then I slew auntie Ethel. After that, I encountered the vampire hunter who's after Astarion. He expressed concern that Astarion might not be dead after all and asked where he was. I told him the location of our camp, and then the other party members disapproved because I'd given up another party member. The same party member that was dead after trying to bite me, and that they were relieved to be rid of? Seems like the game assumes that he's still alive when it comes to their reactions.
