A/N: This has probably been done before, but I couldn't help but write this. I just rewatched the God Complex. For some reason, the first time around I thought that the room with little Amelia was the Doctor's fear. So when I realized it was actually Amy's, I started thinking, what was in the Doctor's room?
Door Number 11. Of course it was his, who's else would it be? Didn't even match the damn numbering scheme. 307, 305, 303, 301, and then big old Door Number 11 at the end. He shouldn't look; he really shouldn't look. Of course he had to look.
Before he even saw anything, he heard the Cloister Bells, and somehow knew what it meant. It didn't help prepare him for actually seeing it, though. And, even though he knew it was only an image, he was terrified. Properly terrified.
He pushed the fear down, forced himself to remember that this was a trick, designed to evoke fear. "Of course." Of course it would be her. "Who else?" She was dying, and there was no way to help her. Nothing could terrify him more than that.
With a tremendous force of will, he closed the door, refocusing on reality, trying to shake the image of the burning TARDIS out of his mind.
