Chances are if you're a Game of Thrones fan, you couldn't help but notice how quickly Gendry ran back to the Eastwatch in Sunday's episode. And also how quickly the raven he instructed them to send reached Daenerys at Dragonstone, and how quickly she and her dragons showed up to rescue the group of men beyond the Wall.
Yes, the show has fire-breathing dragons, and yeah, Arya Stark can turn into anyone just by wearing that person's severed face, and sure, the dead can walk (while others can be brought back to life), but it's the speed of Gendry, the raven, and the dragons that seems to be keeping a lot of viewers from suspending their disbelief.
Looking at a Westeros map, both a messenger raven and the three dragons cross almost 1000 miles verrrrrrry quickly...— Matt Baldwin ? (@thisbrokenwheel) August 22, 2017
