Speaking of last week's show (Noddin' Off) My "GoT" theory, that Jon Snow's Robert Barratheon's basterd's not Ned Starks, just got more plausible with the Red Woman's attempted seduction of Jon at Castle Black. She needed Kingly baby batter to produce another "smoke baby" (probably to pay Roose Bolton a visit in his sleep) but Jon wasn't havin' none of that. She stormed off but not before saying:

"You know nothing Jon Snow..."

Nothing of this true heritage she means. Also Lord "Pinky" Balish gives us the rest of his backstory later on. After Reygar Targaryeon kidnapped and raped Ned's sister, Robert Barratheon's intended... I believe old Robbie boy did the same to Reygar's wife. Jon Snow was the off-spring. Reygar's wife, a Martell, begged Ned or Ned through Robert not to have their offspring live an unwanted life ergo old trusty Ned took the kid in. As I said I've not read ANY of the books but this is just my theory.
