Someone also made a prediction that Dany would be traditionally subservient to her male oppressor Jon. Oops 
I found the episode lots of fun and also totally preposterous even within the fantasy rules. Seems like that’s what they’re going for, cranking it up to 11 by the end.
At the ice battle I thought the one they bagged was another WW. I thought somebody even suggested killing him to take out more undead like the first one did.
