At first it's not Castiel in front of her. At first, it's just another reason to get away, get further back, get safe. She pushes backwards until her back hits the wall, and when she can't go back further she keeps moving, shuffles sideways until she's wedged into the corner where the walls meet.

"It's here, it's here it's watching me I can see them, make them go I don't know how to make them go," she mumbles under her breath as she brings her shaking hands to her head, grips hard at the back of her neck and presses her forehead to her knees. Curled in the corner, she finally turns her head just enough to look at him.

The mirror is broken. It's broken but she can still hear them, and when she moves her gaze from Castiel to the mirror behind him she sags slightly. Her hands loosen and she sits up, drops her head back against the wall and shakes it. "It didn't work. It didn't work, didn't work, didn't work it's not working how are they still there I can hear them laughing!"

And suddenly she points, shifts from sitting against the wall to kneeling as she raises a shaking hand to the mirror, to the space where some of the message is still visible, just day?, and she screams again.
