Fucking 5 episodes is a joke though, really starting to hate on series that are cutting themselves in half and airing half this year, and the rest next year /late this year,
Cracking episode though,
Although one plot hole, said they can never land the tardis there again because of the un stability etc, and it was lucky it was done the once without ripping new york to shreds, however, what about rivers vortex "watch" (sorry a bit tired can't remember any of the correct names ) as its smaller and like she said, a bike not something big and bulky
Or is it now a fixed point in time, because they read the grave stone?
Either way I can see in a series time, or two series time, they might make a guest appearance,
and before you give me any bull shit about its impossible, remember its tv, anything can happen, if they want it to happen, they will find a story line to make it happen,
