Mentioned earlier about Arya laughing at her aunt's death - she wasn't laughing at that directly - she was laughing that the mighty Hounds plan fell through..
I think the Hound dies this season... I hope not, but I'd guess he is a character that doesn't get to season 5.
Yah, Arya's comment about him not walking as fast as he usually does made me think the same thing.
I was half expecting the mountain to confess, then Oberyn throw the spear at Tywin. Didn't expect that outcome at all. I have no doubt they'll still save Tyrion somehow, just don't see how.
Yup, that scene was the warning that Hound is out.
Honestly, with the amount of curveballs from the show, I think it is almost probable Tyrion dies... Majority think he somehow survives, for that reason I think he goes. They always do the opposite of what you expect, since we all expect him to survive, he dies.
I think the opposite. I think so many people expect him to die because it is Game of Thrones, who's not afraid to kill main characters, that it will actually be surprising at this point if he does live.
It's not about main characters and minor characters. It's about static characters and dynamic characters.
Ned Stark, main though he was, was static. Honor, duty, honor, duty, rah, rah, rah. He stood for something, and was a likable and sympathetic character, but his character "arc" was flat. He didn't change from the moment we met him till the moment his head started to roll. Robert, same thing. Robb, same thing.
Authors don't kill off their dynamic characters. Not till the very end, anyway. Because it's their ever-changing character arcs that drive the story. That's what it means when you hear a story called "character based" instead of "plot driven."
Tyrion's a dynamic character. He was a cowardly, aloof, drunken, intellectual whore monger, and the shame of his family. He's become a lot more than that. He's led armies, found (and lost) true love, engendered the sympathies of his golden-child brother. His character is one of the ones driving the story, so he'll live to keep driving storylines in the future.
The Hound's a dynamic character. Arya's a dynamic character. Sansa's a dynamic character. Dany's one. Jon is. The crippled kid is.
If you want to worry about anyone's fate, worry about Cersei (who has been pure, malevolent evil since we first met her), Littlefinger (raw, unthrottled ambition), Tywin (family pride and power lust), and any other major character you don't see growing. Those are the players GOT seems to like to slaughter.
ETA: I'm torn on Jamie.
