The episode starts with the Doctor stepping into a fairy circle, causing him to vanish and locking the Tardis. I'm not a huge fan of this season's "magic is real" vibe, but so far it tracks.
A woman appears and follows Ruby around. She ends up in a pub where she asks about the fairy circle. After a long build up explaining just how serious the fairy circle is, it turns out no that's just racist. Pretty funny, and it works with the magic theme. So how does the fairy circle actually work then? No fucking clue, they never explain it. As far as I can tell it just exists for this bit.
So this woman makes everyone near her hate Ruby. Everyone. Why? Who fucking knows. They never explain why. It just does. It leads up to a politician getting scared and ruining his career. Again pretty clever. But again no explanation is ever given as to how or why this happens.
Then Ruby dies. And when she dies she becomes the scary woman. Then she goes back in time. How? Why? No idea. It just happens and you gotta deal with it.
So apparently the Doctor stepping on a fairy circle that doesn't do anything makes him vanish for no reason, creates an old copy of Ruby that follows her around for no reason, who scares everyone for no reason, then when Ruby dies undoes everything for no reason.
This. Makes. No. Sense.
Pretty sure that's been established.
If the Doctor isn't around, security measures lock it down, even preventing the use of keys.
I took that as a reference to how people don't believe in it, but that doesn't stop it from being real.
Dr Who magic isn't Tinkerbell magic, people don't need to believe in it for it to work.
I think it's not that she "says" anything, it's that standing next to an old her, and looking at present her "breaks their brains" due to fairy magic and perception filter being crammed together. They likely still just see the blur, but subconsciously the paradox ducks with them. Like how when multi doctor episodes happen, the younger versions forget it.
Everything weird is because of the intersection of magic and time travel fields... Someone getting thrown back into time isn't that off the wall. Especially if viewing her life and the fairy circle as two never ending loops.
It's Dr Who mate... Unbelievable things happen every episode, but will likely eventually be explained by really advanced tech
So as far as this season supposed to be supernatural...
That's not new, in Dr Who the British royal family are all werewolves and vampires are real just aliens.
Any sufficiently advanced tech is indistinguishable from magic. Even the Doctors tech is often confused with magic. It's entirely possible all the "magic" is going to be tech from some alien species (maybe more than one) living among humans for a very long time even under the Doctor's radar.
This year I think they're just waiting instead of explaining it away with timely whiney bits until later in the season when it all gets tied up with a bow.
When the fans have to make up explanations for an episode with no textual evidence, that’s good storytelling. I’ve had people tell me that the woman stays at 73 Yards because that’s the range of the TARDIS’ perception filter, but if that has ever been mentioned on the show, I’ve missed that little tidbit. Do people notice the TARDIS at the end of their street, then un-notice it halfway down the road?
It’s Doctor Who mate… even the most mysterious entities have a motive and rules. The Midnight monster is never explained, but we understand how it works, and what it wants. In Listen, it is never confirmed if the creature exists but that is tied into the story of the episode, and we still understand the concept behind the monster. In this episode things happen because they look creepy, and then it ends with what amounts to an “it was all a dream” twist.
Kate mentions this at the café as the distance where a person with 20/20 vision can’t make out any facial details anymore. But there never was mentioned any relation to the TARDIS perception filter.
