Sort of off-topic: when javyn mentioned Ser Jorah and his commitment to his wife I thought to myself "eh? What wife?"
So I did a quick Google search and found this little gem: http://awoiaf.westeros.org/
I've read all the books, and so I thought I'd refresh my memory a bit by reading a few of the articles. I'm pretty sure I need to go back and re-read everything--there's a ton of stuff I either missed the first time around or have forgotten.
Anyway: this seems like a good place to catch up/get deeper explanations for things if the show gets confusing.
