That was dope how the Red Woman brought Jon back after she lost all faith and no longer believed. Exactly like how Thoros ressurected Beric Dondarion.
"I've always been a terrible priest. Drank too much rum. Fucked all the whores in King's Landing. It's a terrible thing to say, but... by the time I came to Westeros, I didn't believe in our Lord. I decided that He, that all the gods, were stories we told the children to make them behave. So I wore the robes, and every now and then, I'd recite the prayers. It was just for show. A spectacle for the locals. Until the Mountain drove a lance through this one's heart. I knelt beside his cold body, and said the old words. Not because I believed in them, but... he was my friend. And he was dead. And they were the only words I knew. And for the first time in my life, the Lord replied. Beric's eyes opened."
