after the first season ends. so many questions comes to mind..

first how will bran's character will be built up..
arya's gonna join her bast@rd brother lord snow in castle black?
robb will lead us all!!

frigin dragons!! dragooooonsssss!!!!!

why did Lord Eddard of house Stark dieeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

that's why most of us went on to read the books, can't wait for the next season to air, it's freaking torture!

and the dragons are really cool, i mean REALLY REALLY COOL!

usually in a TV series i'll find 1 or 2 characters or actors that i hate (especially the actors) but GOT doesn't really have any, i even love the bad guys...

Don't worry. That does not mean much.
4th book and 5th book run simultaneously.
Some characters does not appear in 4th book but appear in the 5th. Some otherwise.
