Some time after she leaves the second floor common room, Door climbs until she runs out of staircases and finds a door at the top. She puts her hand on the knob and reaches for someplace that's not on the other side of that door - until it is. Then she opens it and steps out onto the rooftops of another place entirely.
There are breadcrumbs in her pocket, stolen from the common room kitchen -- she still thinks stolen though on some level she understands that the food was free for the taking -- and she sprinkles them on the edge of the roof-wall.
de Carabas: reads the note in tiny printing that Door ties to the pigeon's leg when it flutters down to eat.
I'm safe in the place you
set up for me. What are you playing at? They *
see* me.
She hadn't signed her name, just drawn a simple, rounded doorway at the bottom of the sheet, then added please hurry.
"You're sure you know where you're going?" she asks the bird for the fourth time. It threatens to peck her on the nose if she asks again. "Sorry, sorry, of course you do."
And then it's gone, into the darkening grey sky, and Door is sitting on a rooftop in London, arms wrapped about herself. Waiting.
