Mattie turns quickly at the sound of an unfamiliar voice, halting with a startled expression when faced with a still-empty room. Being far from dim-witted, however, she hesitantly follows the sound until it leads her to the tablet.

She's just not sure what to make of it, though. So she clasps her hands behind her back and eyes the image in front of her suspiciously.

"That is quite a statement coming from a devil in a mirror, sir. If you release me immediately, I will consider forgetting I ever saw you and will not send for a clergyman to perform your exorcism."

Mattie likely doesn't belief she's really speaking to a devil, but she tends to fall back sharp and clever words when in uncertain situations. This time her tone lacks a touch of its usual bite, however -- maybe the reassuring gentleness is working against her will, or maybe it's the influence of seeing a face familiar in age if not in gender.
