Work Text:
Over and over, the two of them spin around slowly in the living room. Alistair leans his head onto the Doctor's shoulder.
Neither of them notices the snow that has started to fall outside, so engrossed in one another. They continue to dance, the song changing to another.
"Daddy?" a voice calls from the stairs.
The two of them look up, eyes smiling, to see Kate with her hair all mussed over to one side. The Doctor heads over and lifts the girl up into their arms and heads back over to where Alistair is.
The three of them dance.
