This is what happened before, she thinks. Not exactly, but close enough to the way her protective instincts surged up when Casey, the real Casey, bled through the demon's control over her. Of course she would give into that; of course she would want to, hating the sight of someone she cares about so much in pain, and the helplessness she feels in this position. Even that is probably worse than it seems. She hasn't actually done nothing here. She helped get Marcus here in the first place, and even if she won't be the one doing any actual exorcising, she'll help get him back, too.

Still, it fucking hurts. She's sure that's the point, but that doesn't make it much easier.

"I know," she says through her teeth, jaw clenched, eyes sad and furious all at once. "We all do. People who know what they're doing with all this are the wrong ones to fuck with."
