The TV show hasn’t talked about Arya’s warging into her wolf Nymeria(?).
You could have Arya mind control/blend with the wolf and rip Ramsay out in the show, getting vengeance via a vicious dog for the rape of Sansa.
The series probably won’t even start to get its act together against the White Walkers, their version of muslim immigrants.
And i bet they minimalize any future ice wall scenes, would be viewed as a Trump wall. Or they destroy it in some fashion, because i think the writers and directors are going to take politiical sides, obviously anti Trump.
This is a popular series, it would make a good platform to subliminally influence voters.
