A live one, at least. She washed a lot of dead bodies in Braavos.
Or wearing the face just magically gives you the appearance and voice of that person. It may just be a change in how people perceive you, rather than a physical change.
That’s kind of what I’m thinking. Anyone directly seeing or hearing a masked Faceless Man perceives them as who they’re target, but if cameras existed the resulting picture would be a very macabre one of someone wearing a leathery human face mask. I wonder what would happen if you looked at one of their reflections in a mirror.
Why would a photograph necessarily overcome or be unaffected by magic?
And to be specific, I don’t even consider the masks used by the Faceless Men to literally be masks or even the actual faces of dead people, not by the time they’re ready for use anyway.
They have so many physical properties that masks or faces can’t have—they don’t deteriorate or tear. They can be stuffed into a bag without altering them. When they’re put on a mannequin head, they resume the shape of the face of the original owner, which is not what a person’s skin by itself would do. They will fit on any Faceless Man’s head, regardless of that person’s size or shape.
We’ve seen some scenes that suggest that a Faceless Man can wear one over the other, in who knows how many layers.
These are magical items through and through. They don’t follow the rules of physics and don’t have the properties of a real mask or human skin.
I suspect that when we see a Faceless Man literally removing a mask, that might just be a representational depiction of what’s happening, rather than a literal act.
That’s how I interpreted it. It’s dark magic.
I just re-watched that opening scene. After Arya removes the Walder mask, she appears to still be much taller than Frey’s wife standing beside her. But as she turns away, she appears to step down, as if she had been standing on something and hadn’t actually been as tall as Walder. This implies she wasn’t physically transformed. On the other hand, as she walks out of the hall Walder’s robes are swimming on her, indicating that his clothes were not part of the illusion.
Similar in a way to the glam Melisandre uses?
We don’t know what causes the long winters. There is a possibility for a scientific explanation when a legend mentioned in passing is based upon a kernel of truth.
In season 1 episode 2, Daenerys is asking her handmaidens about dragons; Doreah conveys a story about their origin she heard from a trader of Qarth: once, the world had a second moon, it wandered too close to the sun, cracked from the heat and out from it came a thousand dragons.
Our moon plays a large role in keeping the tilt of the earth’s rotation axis stable, the result are regular seasons.
If the AGoT-planet (if it is a planet) had two moons, and one was destroyed, its axis might have become unstable, which could cause more extreme seasons. The loss of the mass from one moon could have changed the orbit around the sun. The orbit could have become more elliptical, which would explain the longer seasons.
But IIRC, Martin has denied this explanation.
The theme of “Ice & Fire” points toward a dualistic nature of the forces in conflict; the Red Priestesses believe that this is true in the world and beyond it.
The origin and nature of those forces could be pure fantasy or a technology so advanced that it showcases Clarke’s 3rd law.
If we are dealing with forces that are locked in a struggle for … what exactly (?), the white walkers and the dragons could be their most powerful agents within the world - even though the origin of the first white walker seems to point toward, well, an experiment gone horribly wrong.
Yet, it is curious that the Children of the Forest had any interest in creating a weapon with the qualities the white walkers show - or gained that knowledge by themselves. It’s not in sync with their nature. And apparently, they only knew the steps toward its creation, but not what it meant to put it into their world. Unintended consequences caused by desperate people, or intended ones by someone else?
Both themes are mirrored by the actions of various characters in the show.
Given its location, you’d expect it to be a colder place. Well, maybe it’s located near the Westerosi version of the Gulf Stream.
Ah, yes, the Dracocentric systems. They are most interesting! 
Finally watched it last night. I though it was good! Not action packed like the last two episodes, but that’s OK. Jon needs to lose the man-bun, though. That is sooooooo last year. I crack up every time the Red Headed guy makes some comment about Brienne. He’s just a love sick little puppy!!
The problem I have with trying to explain the weird seasons as caused by an elliptical orbit or some other phenomena is that we’ve been told that the lengths of the winters and summers are unpredictable and last for years. I would think any astronomical cause would be on a regular cycle. And I would think the maesters in the Citadel would have noticed the pattern.
We don’t know anything about the planetary system there. Could be a lot of reasons for an irregular orbit. I’m thinking maybe their sun has small companion, like a brown dwarf, that occasionally affects the orbit of the planet. Tilts it a few degrees every few years, and occasionally the orbits line up so that the planet gets tilted a lot. And then eventually the planet rights itself again. That’s a lot more possible than, for example, dragons and zombies.
Like Elephants.
And Turtles.
Clearly a Wizard did it.
Now that Brienne and Sansa are in the same place, does Sansa know that Arya is still alive and was last seem with the Hound?
Why the chains in the library?
How does Varys get from Merreene to Dorne and then back in time to get on a ship heading for Dragonstone?
The chains are there to keep the books from disappearing. Back when libraries were the only repositories of knowledge, books were priceless. So they were chained to the shelves. That kept people from shoving them into their doublet and going off to sell them for mead money.
See post 99.
Off-topic, but you reminded me of something I just read, about a dude in more recent times (the 1980s), who posed as a college professor and went around looting rare books from college libraries. Apparently made off with $100K+ worth of books that way.
Didn’t that already happen? Or am I remembering wrong?
Brienne told Sansa about Arya and the Hound way back in Episode 2 of Season 6, just after rescuing her from the squad of Bolton men sent to find her.
