Cool standoff! My hope here is to buy time for the others to get in the house and to the attack that they saw us enter. Admund overheard Brunhilde mention that she thought Heinrich was dead, so he's going to use that to his advantage, rather than saying what he really knows about her and her activities.
This will buy time for Klaus to enter the scene. He can use his Blather skill to keep her distracted, and we can keep chatting with her to buy time for our allies to get into the house and up the stairs to trap her here. She thinks Heinrich to be dead, and I'm hoping for a surprise for her when she sees him again.
Alright Klaus, let's see your chat up skills!
