While she was definitely confused to start with, it's only gotten worse as the conversation progresses, anger abandoned to watch the complete switch of Mystery Dude's personality at Clara's arrival. Because he's making no sense, suddenly polite and stuffy and it's another possible landmine to avoid but she can't tell the cause and what.

There's lasers being bored into Will's skull, courtesy of Aradia. Why is he being weird today, she's so sure it's tied to whatever caused his midnight meltdown, and-- "We're not fighting. He's just being an idiot."

Admittedly, a heartbeat later it sinks in that that was probably too far again, but she's in too deep now. This is apparently the mountain she re-dies on. Funeral tickets will start being sold at the attendance booth out front for half price in half an hour. But it's softened a tad, even if only towards Clara, because she's an innocent in all this. "But I didn't realize this was near your Haunt, sorry. I'll try to be more careful."

If she gets more wannabe exorcists on Clara's tail because of her stupid temper, she'll never live it down. Mostly because she'd do her part to drive them off herself.
