Admittedly I wasn't that into "Game of Thrones" during the first two seasons. I watched here and there, but was by no means a full fledged fan. Enter Season 3 - - I've been hooked, but found myself asking my boyfriend "who's that?" far too many times.
In an effort to up my knowledge on the back story (and annoy him less lol), I found the "Idiot's Guide to Game of Thrones" put together by the Screen Junkies.
Game of Thrones airs Sunday nights @ 8p on HBO. Do yourself a favor and watch it!
