ASoIaF (questions and spoilers)

I'm about halfway through A Clash of Kings, and I have two questions I must know the answers to:

Does Joffrey ever get any sort of comeuppance? 'Cause he's a total bastard.

Do the dragons in this series have forelegs or are they like wyverns and do they talk eventually?

Well, to be honest, they aren't IN the fourth book, because the fourth book focuses on King's Landing and the Riverlands.

The Fifth book will mostly be the North and Daenerys. As I recall, in the third book they're getting big enough to fly under their own weight.

I don't really think there is any particular THING that makes you hate him more than Ned, it's just that he maintains a steady level of total dickness.

Do you hate Tywin yet?
