Molly watched as Professor Ezra walked out the door. She waited, sitting there on his bed awkwardly. She glanced around, just taking everything in as she waited. When she felt that she had waited for a long enough time for Professor Ezra to have cleared the corridor outside, Molly transformed back into her human self.
Moll stretched, being in such a little body sometimes made you cramp up. Quickly, Molly scrambled off of the bed - now it was even more awkward. Slowly she made her way to the door, trying to make sure that she didn't make too much noise (attention was not something she wanted right now.
Molly reached down, grabbing hold of door knob and slowly turning it. As quietly as she could, she opened the door. When it was open a good bit, she transformed back into her puppy dog form and crept out of the room. She stood there for a moment before realizing that she'd not have to close the door. She let out a frustrated noise before looking up and down the corridor. She seemed safe for now and so she quickly turned back into her human form, closing the door quietly. Well, since no one was around, it would probably just be easier to walk off in her human form.
She'd have to come up with a plan, though, if she was caught down here in the dungeons... maybe she had set a prank up in front of the Slytherin common room, but it was a dud. That seemed like a logical explanation to her.
