She dumps the burning tongue onto the floor just in time to avoid getting burned too badly, although the edge of her sleeve catches fire and a lock of her hair twists, crinkles and disintegrates in the heat. As the teeth snap again she's knocked off her feet, and somehow one of her shoes falls off. She scrambles as fast as she can away from the mouth as it falls apart and submerges back into the wall entirely.

She gets back up right as the refrain of the song fades, slapping dust and ash off her shoulders and knees. Unlike the Doctor, she does not approach the hole, but keeps a safe distance. She takes a few deep breaths and puts her hands over her ears for a few moments, before digging her own fingers in to try and make sure that they're still clear. No Yeerk, no library. She bites her lip.

"Right, the dumbwaiter," she says, although the encounter has stoked that rebellious side. She gives the Doctor a steely glare. "At some point are you going to bother explaining any of that to me? Or how about anything beyond your most superficial interests? Do I ever get to know you, Doc, or do you just expect me to follow you around like some curious animal looking for treats while danger hunkers in the corner waiting for me to let my guard down?"

Just because the threat is gone doesn't mean her anger has left her. She's just shifted targets.
