To somewhat of her own surprise, Mallory managed to wrench herself from Jessica's grip and sprint down the flight of stairs before opening the door on the next landing and streaking a bit down the hallway and hiding herself in the corner of the room. To even greater surprise, she was able to lose Jessica, which she could confirm after several minutes of catching her breath in relative seclusion. It was close, though - Mallory could see Jessica standing naked in the hall arms akimbo, looking around intently to find her prey.

Now that she was free, she considered her problems and her options. She had no idea where Olivia, and by extension her clothes and phone, were, and it would be stupid to go all over the school to find them. This left her with two options: either go down to the Lost and Found to get some temporary cover, or go back to the bathroom where this all started and hope her stuff was still there.
