Gwen peered avidly into the dark. She couldn't see around the damn hood of the cloak. While she was great at gazing right through magical disguises she couldn't see through fabric itself. She frowned sharply, the glass she pushed her forehead against was cold.
There was only one way to find out who the dark figure was. While it was risky, the curious side of Gwen was biting too hard. She couldn't ignore it any longer. She got up, threw her cloak over her pajamas and sneaked quickly and quietly from the Gryffindor dormitory. She rushed down the stairs, fortunate in her flight that Filch was no where to be found.
She slowed immediately as she came close to the main hall. Whoever it had been on the lawn was now prowling around outside of the Great Hall seemingly searching for something. In her rush she had forgotten her wand, but as she reached in her pocket she realized she had never taken it out of her cloak.
She pulled it out carefully, prepared to defend herself if this marauder proved to be a problem. She stepped down from the last stair and slunk along the wall opposite the invader. She held her breath as best she could and concentrated very hard on being invisible.
Whoever it was sensed a presence. The hooded figure turned around and she caught her gasp before it escaped her lips. With one hand covering her mouth and the other clutching her wand she stepped out from the wall and let herself be seen.
"Gwen?" The figured asked in a confused whisper.
"Graves?" She replied in question.
