Many "Game of Thrones" fans have been a bit perturbed this season by the apparent discovery of teleportation in Westeros, with characters jumping across the continent in the blink of an eye, and Sunday's episode seemed egregiously fast.
In what felt like a few hours, Jon and his Fellowship of the Wight had trekked north of the Wall, a zombie polar bear attacked, the Night King's army found them, Gendry ran back to the Wall for help, a raven flew to Dragonstone to deliver that message, and Daenerys arrived with her dragons.
Alan Taylor, who directed "Beyond the Wall," admitted the timing is "a little bit hazy."
"We tried to hedge it a little bit with the eternal twilight up there north of The Wall," he told Variety. "I think there was some effort to fudge the timeline a little bit by not declaring exactly how long we were there."
He was aware that fans would take issue with Gendry becoming a track star and what seems to be the fastest raven in Westeros.
"They seemed to be very concerned about how fast a raven can fly but there's a thing called plausible impossibilities, which is what you try to achieve, rather than impossible plausibilities," he explained. "So I think we were straining plausibility a little bit, but I hope the story's momentum carries over some of that stuff."
And one Redditor figured out that the timing is entirely plausible.
Taylor doesn't mind fans checking the math. "It's cool that the show is so important to so many people that it's being scrutinized so thoroughly."
