I found a screenshot of the letter that Jorah wrote to Khaleesi in Episode 2 assuming it's going to be his last night:
So much love <3
I think Brienne actually killed the Hound when they fought and the Lord of Light brought him back, like he brought back Jon Snow and Beric.
If that's true, then are all Hound, Jon, Beric etc. ...
It might be. :)
