So what do you think about Ned and Wylla?
Jon Snow was born after Robb Stark. Robb was conceived on the Catelyn's and Ned's wedding night before he left for battle.
Wylla was milk mother (wet-nurse) to both Robb and Ned Dayne. I don't think Ned would have known her early enough in the war to have a child with her and as I said, I don't think Ned would have violated his marriage vows, especially so early in the marriage.Warning: Spoiler! (Click to show)
I believe in R+L=J.
I also believe the "Promise me Ned" vow he took was what caused him to deceive his wife and make her believe, along with everyone else, that he had fathered a bastard conceived after his wedding. The evidence is circumstantial, but somewhat detailed and sprinkled throughout.
Lyanna was in a bed of blood when Ned found her. That's been used other times to describe the birthing bed. Arya is described to look like Lyanna. Jon is described to look like Arya.
The other Stark children share more features with Catelyn. Targaryen traits are also recessive traits in the Westrosi genetics, so Starks would dominate them. No different than Barratheon's all have black hair, Targaryen's who marry the other Paramount families lose their Targaryen traits. Dornish may be the only more recessive group. So Jon Snow looks like a Stark, not a Targaryen.
Targaryens not only practiced incest, but also polygamy. I think Lyanna married Rhaegar. I think the affair started when Lyanna fought as the Knight of the Laughing Tree and Rhaegar found out and fell in love with her. See the story that Jojen and Meera told Bran before they got to the Wall. Lyanna was a great rider and practiced with swords and lances instead of lady activities. The Knight was small and had mismatched armor- stolen by Benjen, I believe. Benjen went to the Wall in the shame in what part he played in his sister running away with Rhaegar.
Jon is the Prince Who Was Promised; The Song of Ice and Fire; Azor Ahai reborn.
He will be born again (A Dragon awakened from stone) when his frozen body is burned by Melisandre in a pyre at the Wall. She has been looking for King's blood to awaken the dragon from the stone. Rhaegar's son has King's blood.
Melisandre keeps looking into her flames asking to see Azor Ahai and keeps seeing nothing but Jon Snow, because it's not Stannis, it's Jon she's asking to see.
