So, Tyrion is played by his sister once again. No surprise really. You'd think he'd know better by now. Maybe he does know? And what was the deal with him creeping outside the door while Dany and Jon were in the sack? It is definitely looking like he might be the betrayer, but I just can't bring myself there yet. Especially since his love is definitely for Jaime, not Cersei, and Jaime just rode off into the sunset.
On that note, we see just how terrible the wight mission was. No new ally, and you gave the NK the ultimate weapon.
We explicitly found out that Jon is a legit Targ. Will he have his long needed talk with Bran now that everyone is converging on winterfell? Or will they divert and head further north now that the Dead are coming? I hope they don't leave that hanging out there as it will add a new dynamic to the Dany and Jon saga. Jorah definitely tried to keep them from being on the same boat together, and of course, the aforementioned Tyrion creeping.
We finally got a straightforward time estimate from KL to Winterfell. 2 weeks on horseback.
Sam's reaction to Bran was great! I may actually end up liking this Sam guy after all.
Rhaegar, his ex-wife, and first 2 kids were killed shortly before Jon was born. The war was started because Rhaegar "kidnapped" Lyanna, so the deaths happened after they were married.
I believe the ice dragon breathes ice breath not ice fire breath. It looked like it made the wall so cold and brittle that it crumbled under it's own weight instead of melting it.
No way Tormund and Beric are dead. Beric still has to accomplish something, otherwise being brought back to life a dozen times makes no sense. And, you just can't get rid of Red Beard yet.
The Littlefinger end was satisfying. I was hinging there for a minute, like, ok girls, don't tell me he still has you crossed.
