Morgana wasn't going back to Camelot, not ever. She'd stay with Amy forever, she thought. They fit, Morgana and Amy, in the TARDIS, bigger on the inside, with its never-ending corridors and rooms that never stayed where you'd left them. But in Leadworth Morgana didn't fit, and neither did Amy, not really. And for a while they didn't fit in together, but you can't live like that forever.
