I assume that we are supposed to assume that months or something pass between episodes, months in which the Doctor was all emo in his room and wrote long epic poems to Pompadour's breasts and Mrs. Moore's gadgets and came up with increasingly inventive reasons why he couldn't go back in time to see her, even if only for a quick snog and a chat about how very lonely his childhood was. I suspect Rose spends those months regretting not playing 'interrogate the prisoner' with Mickey quite a bit and wondering if the Tardis recorded any of it for research purposes.

Hee! Oh, if these TARDIS walls could speak . . . ew. Actually, better if they didn't. Speaking of which:

I think either his mum was a Cardiff native or the Tardis has a police box it's shagging there.

The TARDIS materialized around a real police box in Logopolis, so technically it/her signifigant other is by a road somewhere in 1980's England. OMG ITS CANON
