Oh, but it gets worse:
Nixon: "I think the Moon is far enough for now, don't you?"
Canton, resigned to being a poor old idiot American: "I figured it might be."
Nixon: (Eyes bug out, green around the gills, pulls on his collar, edges away from the queer.)
It's not just that it's anachronism solely for the reason of being antagonistic, or socking the US with one final suckerpunch. It's not just that gay marriage is a punchline, or the "weirdest" thing they could think of, regardless of how little sense it makes in context. It's not the casual references to miscegenation and the beginnings of the bloody fight for civil rights in this country, about which honestly British people shouldn't even be commenting, or that you're not allowed to point the finger at somebody else for intolerance when you're doing the exact same thing under the self-righteous guise of tolerance... It's all of those things. It's the fact that Stonewall was that year, and Hoover was the head of the FBI, and here you have this hard-headed dude who gets thrown out of the FBI not for being gay but for demanding to get married -- which, what? -- and then acquiescing immediately... Because of the moon landing? Dumb. Hateful and dumb.
I'd feel like a real hypocrite... If I hadn't spent the last season bitching about the way this show now treats women the exact same way.
At the Stormcage the Doctor invites River to stay aboard, but she points out that she escapes whenever she feels like it -- to the point they didn't even bother showing us how this time -- and that she's got a "promise" to fulfill, which he'll eventually understand. (Spoilers? Or is this a known thing she's referring to? The old story about their relationship would seem to suggest it's a clue, but the retcon in this story that they're back-to-front implies we already know what she's talking about, which means the Doctor should too, but obviously the reverse is true.)
He leaves without a kiss, and she's surprised; she pulls him in and lays one on him, and his arms flap around and flail. Somewhere along the way, as he's backing slowly into the TARDIS, looking terrified, she realizes what's just happened, and her heart breaks a little.
Doctor: "You know what they say, there's a first time for everything.
River, when he's gone: "And a last time."
The Doctor sends Rory into another TARDIS room for some technical stuff, and discusses with Amy about how she is or is not pregnant. She says no, but it turns out that "is or is not" is closer to the truth, as the Doctor sees at the end of the episode in a second: A scanner thing keeps flipping back and forth between both states, like Schrödinger is the babydaddy. So they have this whole conversation about how she told the Doctor but not Rory about the scare because the Doctor is her "best friend," aww, while Rory's just... Rory.
