Hey, I just posted what the guy wrote! I saw the episode and that was a surprise. It was really to show the following I suspect:
1) she wasn’t kidding when she said she had been fighting longer than the people around her (she’s quite old).
2) how dispirited she is that Stannis is dead.
(Maybe she gives her life in episode 2 or 3 to bring back Jon Snow just like Beric Dondarrion did for Catelyn Stark/Lady Stoneheart in the books?)
LOL!!
I still cringe thinking of that scene!
I think you might be right about the Red Witch. She might resurrect Jon, knowing that this would be her end.
