A strange blue box appears on Roald Dahl Plass and a choice is made, a choice to travel time and space. But everybody gets homesick. Torchwood: Set just before End of Days, Ianto doesn't know Jack's immortal and isn't there for the whole Abaddon ordeal, also he has never heard of the Doctor. Doctor Who: Set before Smith and Jones because who's to say the Doctor didn't have more adventures before then. Also AU (eventually).
