I did not notice that the Hound was foul mouth. I only know he acted heroically with Sansa in two different occasions. And with Arya, he treated her with affection and caring. He was naturally a protective man and that appealed to me and despite his rough edges and that he wanted Arya,so he could get a reward, he was one of the few characters in GoT that when he died, I wished the story could have changed.
What a great actor to boot! I hope he gets more roles in the future that showcase his talent.
LOL he said the C word a couple times, the F word a couple times, called Brienne the B word. Anyways, I also loved how he acted chivalrous towards Sansa and also how he cared for Arya but didn’t like to let it show. Since the show writers aren’t sticking conclusively with the book material who knows? Maybe there WAS a maester hiding behind one of the bushes and Hound returns wounded, but alive next season:)
