[OOM:
"I ain't afraid of no ghosts!"]
The front door opens, and the Doctor runs through.
Wait a minute... the front door?
The Doctor looks around and realizes suddenly where he is.
"Oh, no. No no no."
He drops the two objects he's carrying to the ground with a resounding thump and whirls around to the door.
Which isn't there.
"No no no NO!" he yells, slamming the bare wall with his fist.
