Quoted from vicjw66:

How will they bring the captured wight back through the wall? Benjen Stark (who is half wight) could not go south of the wall due to the wall's magic preventing the undead from passing through. The only way to bring a wight to Kings Landing is by killing a human north of the wall, then bringing his corpse through the wall before he turns undead. Correct?

Quoted from Lethal_Inc:

No way Jon Snow is Targarian. Do you see any blond or white skin?He is the son of Robert Baratheon and Ned's sister, whatever her name was, and the true heir of Westeros. We'll see....

Quoted from Lethal_Inc:

Just because the "mad King" raped her doesn't mean Jon is there child. It is possible that Jon is Robert's true son and was hid for the same reasons, actually more from Cercei. There is no concrete evidence yet so don't be so certain. Robert told Ned multiple times that he loved his sister. Just sayin...Jon has darker skin and black hair like the Baratheons and Starks. Like I said, we'll see. Jon and Dany are hookin up and then that would be incest according to you guys.
