You sound silly right now...there's a thread just for the book readers if your so frustrated. Otherwise, half of the fun of watching a show is figuring out the twists and turns.
Have you watched the show? You and Tical be asking questions that are plane as day in the show. Has nothing to do with book readings. A lot of the info I have it from watching the show, and reading on the internet. Hello in the show Jon Snow takes a vow/oath. WTF does that mean to you? An oath to something means forever. Did you miss when the deserter had his head chopped off? That imagery means for fucking life dummy. Jon Snow options in life are limited due to him being a bastard. What do you guys not understand. Only way he can do something as a Stark is if he is legitimized. Also remember he was raised by Ned STark who taught him honor so he would never go against his oath as a Nightswatch. I ain't read no book but I know enough about it.
