Penny heard the door crack open and tensed. She didn't head anything beyond Ophelia's hello before her hands curled into fists. Whoever it was, if they were tenants in the building too...theorectically speaking, then they wouldn't be friendly. Penny went to stand a few feet behind Ophelia, just in case. Who would know where to find them? She could only tell herself not to be paranoid and hope it wasn't someone who she would have to hurt. That meant they were friendly. She crossed her fingers as the door was flung wide open, the hallway beyond it visible and tension hanging thick in the air.
