I think that the Doctor guarding Earth and its environs from major threats definitely counts as guarding the Vault by extension. I get the sense that the TARDIS understands the vow too, as she hasn't been leading him too far astray either. There's not much suggesting he's had many off-world visits since he took the…

Don't worry — they get two more episodes.

The BBC synopsis of the final episode of this arc, "The Lie of the Land", reveals that your idea is pretty much that episode's premise — audience knows the truth, he doesn't…guess the species catches up with his cleverness!

There's no evidence on display that she has; remember, the real Bill is only seen in the ending. I suspect this will come up by the end of this "Monks" arc, though (the next two episodes).

Possibly…but does it even matter given what's going on?

I think it's because, from what I can tell, no one's figured out how to properly visualize it with live actors yet as the characters are a mix of humans, animals and fantasy creatures. And the actors can't move in all the dimensions needed to make the undersea scenes convincing. The Broadway production was roundly…

Along with my weekly "Doctor Who" fix with the fine "Oxygen" (glad I didn't get spoiled on that ending, but…ow), I enjoyed "Class"'s "Nightvisiting". It would be easier for me to keep up with "Class" if I weren't so busy processing the current Who season, but it is an exceptional spinoff.

Just out of curiosity — what loose ends/questions of the Twelfth Doctor's tenure do you want to see wrapped up by the time he regenerates? On my wish list, there's:

Yeah, the explanation (the suit couldn't completely kill her) only half-made sense given how bad she looked. Unless SHE has a healing factor she doesn't know about. There are a LOT of theories floating about that the Doctor's interest in her is more personal than he lets on.

Yeah, I am bothered that his "healing factor" isn't kicking in already. Perhaps he can't regenerate yet for some reason, i.e. there are things he has to do first that he can only do in this incarnation, and we'll find out what those things are in coming weeks.

Also, it's one of the few "fun", low-stakes episodes of Capaldi's tenure, a relatively angst-free story. After that there's "In the Forest of the Night" (which is silly but kinda sweet), "The Husbands of River Song", and "The Return of Doctor Mysterio". Granted, there's still a few Series 8 episodes I haven't…

The Doctor getting bored with the archery tournament and just blowing up the target with the sonic gave me one of the biggest, longest laughs of my life and confirmed I was going to loooooooooooove CapaldiDoc in a way I hadn't loved any other new series Doctor.

When all there was was Series 8 and I asked three people (including MaryAnn Johanson the Flick Filosopher, who loathes most of Series 8 and 9 — I don't know what she thinks of 10) which Capaldi stories to start with, the one that came up most often was "Robot of Sherwood". Johanson also recommended "Time Heist" where…

It was so pricey that the rest of Series 1 effectively had to "pay" for it with lower budgets than they might have had otherwise.

Yes, that too. I didn't hate "Hell Bent", and I don't see where a simple revenge story some fans seemed to expect would have worked. But it would have been more interesting and moving to have a story in which the Time Lords, Ohila, Me, etc., were forced to confront the sadistic evil that was done to the man whom…

Yeah, it was curious about the keyboard. Maybe it had Braille on its keys? Raised letters/icons? I don't know much about what's possible there.

Meanwhile, down in the vault…I find it odd that the Master/Missy would have the ability to psychically sense the Doctor being injured or killed, especially from afar. Why would she needed to have been observing him via the tablet in Series 8 if she had Force sense? And what about the Time Lords in the final arc of…

I really want to see something like that. Or, as butterfly-in-the-well on Tumblr has suggested, the Sonic White Cane!

About it being unusual for the Doctor to lose an argument…it's true it doesn't happen THAT often, but sometimes it feels like poor Twelve keeps getting chewed out by everybody. Heck, last season's finale was all about a poor, mentally damaged man — who just wanted the woman he loved back and justice for his suffering…

It will be really interesting to see how the show handles the blindness issue. On a character level, what will happen when Bill realizes her friend effectively maimed himself for her sake — how do you deal with that kind of sacrifice, even if he would never ask for it to be repaid?
