I think Tyrion does deserve a happy ending. He is by no means perfect, you're certainly right about that, but as far as characters in the series go, he's one of the nicer ones.

But even there, I recognize your point, and I agree wholeheartedly with all the rest. Particularly the Daenerys bits. That's why I was so happy with the Tyrion chapters, I think, because he recognized that being a slave might actually be a better lifestyle than that of commoners in Westeros, or at least not one that is in any way inferior. Thoughts like that, and his whole general personality, gave me some semblance of hope that a dose of Tyrion would make Daenerys finally a decent character. But considering how Daenerys does all her thinking with her vagina, and Tyrion thinks with his cock half the time as well, perhaps he won't be able to make her process any new thoughts after all.

Btw, do you see Daenerys as some kind of alternate universe Egwene clone?
