Dom had forgotten that she'd locked the door before asking Sirius to come. At the voice, she started, but then stood up, slowly walking over to the door. She took a few deep breaths before unlocking the door and opening it. "I forgot that I'd locked it," she said quietly as she opened the door and looked at Sirius, clearly rattled.

Everything would have to be done the muggle way and while that worked for most of the population of earth, it wasn't something Dominique was looking forward to. "So. Er. Hi." She wasn't quite sure where to start.
