Yeah, if I had to choose I'm usually on Team Arya but she's such a gigantic bitch to her sister, at a time of extreme duress for everyone, that I lean towards Sansa this time around. Who the fuck cares if she wrote a stupid letter under duress 5-6 years ago? Hello, the Army of the Dead is coming. No time for the petty grudges of your sisterly rivalry.
And travel times obviously are of no consequence in this show anymore. If Euron can sail across the continent in one episode, it's not out of the impossible for Gendry to sprint back to Eastmarch (smithing builds up cardio, yo), the raven to reach Dany, and Dany to rush halfway across the continent herself with 3 dragons in, what, two days at most.
I'm more amused by the fact that these guys went beyond the Wall... with no mount, no food, no supplies of any kind save from Thoros's apparently bottomless flask. I mean, having these characters interact was fun as hell, but the entire expedition is just stupid beyond words.
Also yeah, Jon should have died of hypothermia the moment he got tossed into that lake. Especially considering he just spent at least one or two days freezing his ass in one place with no food and no fire.
