I'm a little surprised no one has mentioned that the ending of this episode, with a character in a VR simulation getting a message out to the real world to foil the villains, was in a Babylon 5 episode.

According to an interview with Moffat, he wrote the episode before the election, but filmed it afterward, and he wrote a note in the script that he didn't know whether the President should be a man or a woman, but they'd know by the time they were shooting.

I don't recall having to watch "Cyberwoman" after finding out what the Hybrid might be.

Apparently just the Earth. Possibly not even the whole Earth, given the projectors we saw all opened into strategically important places. Heh. Frustum-culling the planet.

I briefly considered if the Doctor might've been guarding the vault before he became a professor (maybe the school came up around it, and him), and we might be near the end of the thousand-year timer, but then I remembered he's still 2,000 and change.

I remember on another board, up through season seven at least, there was a small but vocal contingent who was convinced that every season was going to end with a total continuity reboot. Matt Smith (or David Tennent) would now be the First Doctor, and none of the prior adventures would've happened.

The Pope was also untranslated in the scene after that one, before they entered the door hidden in the painting. The Doctor might've just been humoring the Cardinal by allowing him to translate.

I'm a little confused about the timeline with regard to Nardole. In the flashback, it sounds like the Doctor came directly to Missy's execution from his date with River, and then River sent Nardole after him (and, I don't know, Nardole swung by the Library five minutes after the Doctor left to high-five Library-Clara…

I always thought that was more of an RTD thing, and the first part of Moffat's era was in dialogue with that. Like, RTD-era episodes asked "Is the Doctor really a bad guy?" and then shrugged "Sure, probably, why not?", and Moffat-era episodes asked "Is the Doctor really a bad guy?" so they could answer, "No, and you…

Well, it's possible she was more fucked up, I wasn't looking that closely, but she seemed fine from the head up, aside from being dead.

I wonder what Elon Musk and all those simulation truthers thought about this. On the other hand, it does bring to mind a certain issue I've had with that idea; namely, arguing that our reality is a simulation is a roundabout, cyberpunk argument for the existence of God (for the most open-ended definition of "God,"…

I meant it was a dream twice in "Last Christmas." "Heaven Sent" would bring us up to… a couple hundred billion times.

Also "Last Christmas." Twice!

Probably because they keep calling her that.

Maybe the Daleks were all, like, "Didn't we sentence you to death and execute you?" And she was like, "Um, that must've been one of my future incarnations." And the Daleks were all, "Well, no time like the present, lawl time-travel humor.

And what a medieval pope!

Ridley Scott apparently has six movies in mind to get there, but the short answer is probably that the Engineers probably live on more than two planets, and that David is deeply invested in killing things.

She didn't. It looked to me like she'd just been dissected.

He walked her through it. https://www.youtube.com/wat…

You're overlooking something subtle but critical in this film and Prometheus. David fucking loves murdering people.
