Headtilt. "I don't recognize you, and you definitely aren't that berk I was defusing the array of - so, I don't know why you'd even want to."
"If you're with that berk, then killing me wouldn't hide evidence - I'm not dumb, I reported back before going in, and I have a check in due - and would dig you in deeper - though the Fuhrer would be the least of your concerns, then. He'd probably even still give you a trial." She's not bluffing, here. She does in fact have check ins, and she did in fact report (there was a tiny amount of evidence gathered after that, and she did also just admit to not knowing this woman, but also she's very confident a minor gap in evidence won't matter to the Dust nor Flame Alchemists).
