Doctor: You aren't going to shoot me, I just got in the Oval Office.Broomstick wrote: In regards to spoilers next time – clearly, The Doctor spends some time as a prisoner, what with the chains and beard and all – I'm assuming he's held by the Americans. Which is puzzling, because in 1969 America how could the US keep The Doctor confined against his will? This is a guy who saves the universe barehanded, no plan, no backup, no TARDIS, not even his screwdriver sometimes. Unless he lets himself be held? Or maybe the Americans don't rely on fancy tech and just has guys with guns stand around him for a long time? The other thing – if they do hold him that long they have to figure out at some point he's not human in which case where's the guys in the white lab coats who want to do a dissection?
Alright, I'm probably overthinking this....
River: Doctor, They're Americans
Doctor immediately surrenders.
Keep in mind, unlike the Daleks, Cybermen, whoever, Americans shoot.
