Her eyebrows creep up a little at Norah's snippy response. At first, the ignorance surprises her more than the defensiveness, but 'haunting place' does provide a little clarity. If any kind of ghost can fairly claim ignorance to what's going on in the rest of the twilight, it's a house-haunter. They don't get out much. And they skew close enough to homesteaders for more mobile ghosts (especially the ones that want to stay mobile) to keep a respectable distance.

They don't get out period, actually, which makes Norah's newfound freedom both interesting and potentially alarming. "You can leave?" Rose asks, sounding about as dumbfounded as Norah did a moment ago. It doesn't sound like said haunting-place was destroyed (a word which only means anything in the daylight, anyway), and it takes Rose a dragging second to imagine another reason why a house-haunter might find herself suddenly at liberty to wander. Her expression darkens. "Shit. Were you exorcised?"
