You go to learn more about the killing angels instead of Vaggie at Carmilla's house she's saying

Carmilla: Give me reasons I shouldn't kill you...

You try to explain but

Carmilla:I was cornered in that last extermination, well gotta say you don't become an angelic arms dealer without arming yourself first...

Carmilla:I see you're driven by your detestation Your every step is stoked with animus You need a different type of motivation Or there's no way that you can handle this!

She pushes you onto the ground then steps on you with her angelic heels.

Carmilla: I know your a past exterminator like Vaggie...
