Spoilery opinions (I only watch the show):
I want Jon to join the army of the White Walkers and slay his former comrades. Especially the second-in-command.
I was happy to see Sam and Tyrion stay away from the action. Although Sam killed a White Walker, and Tyrion survived a lot, they aren't cut out to be champions. They have different strengths.
I think Arya should've either killed her assignment, skeedaddled, or both. I think Arya would be better off on her own.
Sansa and Theon are totally committing Self Delete.
Cersei is totally going to use her Frankenstein to get revenge.
