At the sound of the knock Fuu gave a start, scratching a long line in her journal where she'd been writing. She listened for a voice over her suddenly pounding heart - ah, it was Mister McCrimmon?

"J-just a moment-" she called back instinctively, then winced. Looking over to the side, she could see her reflection in a decorative mirror. Her face was pale and her eyes dark, her hair sticking up a bit oddly in places from having slept on it when it was wet, and her white blouse rumpled for having slept in it.
And that was just what was in the mirror.

In short, she was really in no condition to be seeing someone.

Rising to go to the door, she leaned against it rather than opening it.

"Please forgive me for speaking to you through the door, Mister McCrimmon," she said. "I'm not really... presentable to greet you just now."
