In some ways it’s disconcerting, having the Doctor here in such a normal, non-alien setting. In other ways, Amy knows that until he appeared everything felt wrong, even though it was her wedding day and she was marrying the man she loved. There’d been something missing, something of vital importance to her; now she knows what that was.
The Doctor dances over to her, Fez at a rakish angle, grinning happily.
“Oooh, is that trifle? Can’t have a party without trifle!”
He’s ridiculous, her raggedy Doctor, but he’s the most welcome sight imaginable. All’s right with Amy’s world once more.
