10 of 13 I mean, seriously?! I edit out one spoiler just to find this same title in the HNQ with another spoiler?....... I don't want to know of an rescue incorporated with Dany that takes place at the wall... All this was allready spoiled by this title to me jsut 12 hours after episode is available to me...

Was these characters' rescue achieved in a plausible time?

In Episode 6 of Game of Thrones Season 7, "Beyond the Wall", Jon and the group that went beyond the Wall to bring back a wight to King's Landing find themselves surrounded by the dead. Just before this happened, Jon asked Gendry to travel to the Eastwatch-by-the-Sea and send ravens to Dany in Dragonstone to help them out beyond the Wall.

Even if the TV show is running the time a bit faster, episode wise, it would still take a bit of time for:

Gendry to travel back to the Wall. A raven to get from the Wall to Dragonstone. Dany riding off to beyond the Wall to help Jon and company. Given there's a lot of geographical distance at play here, how much time passed between Gendry splitting from the group and Dany getting to them?
