Just watching BTTF2 on Freeview now and thinking it'd be cool if a villain tried to alter a companion's history - yes I know this was the plot of Turn Left - but the Doc and the companion were aware of it.
Companion is fraught with concern over their family who have been utterly fucked over in the new timeline (like Marty's family... his Dad murdered and his Mum married to his arch-nemesis) but the Doc is on the case... all the while trying not to run into their past selves (like Father's Day but even more so... imagine if it were Rose and Ten trying not to run into Rose and Nine...)
Steve Moffat loves time-travel as a plot point, here's hoping we see this sort of thing during his tenure.
