Re: Jon Snow
Regarding Wylla (sp?): Robert makes some reference to a time when he and Ned supposedly went wenching in their youth; Robert remembers her name was Wylla, Willa, Millie, or something like that. Perhaps it was in Dorne at the conclusion of the war. In Robert's mind they were wenching... He was probably drunk as a skunk... We know of Robert's affinity for bar maids... Soooooo, it would have been easy enough for Ned to lie to Robert about a roll in the hay with some local girl named Wylla... and when Wylla shows up later with a babe at the breast, Ned is proven to be the father of the child, no further questions.
Theorycraft, this has been discussed on this website and others.
Now the questions are: Did Ned really go wenching or is Wylla a participant in the cover up of Jon's parentage?
If Ned + Wylla = Jon, fine, Jon is the ******* son of Ned Stark as we've been told all along.
If Ned + some other local girl = Jon, then why involve Wylla and not the real birth mother?
If some guy +Wylla = Jon, why on earth would Ned get involved?
If Jon is the son of someone dear to Ned, then Ned might need to lie and create a cover story for Jon. Lyanna, Howland, Ned's men, and perhaps Robert were the only people that we know of whom Ned loved and were down in Dorne near/at/after the end of the war. If it was Howland's *******, Howland could have done as he pleased with him. If it was Robert's *******, why did Ned favor him above all the other bastards that Ned met in his life? If Jon is the ******* of one of Ned's men, giving him a job would be more than enough... why adopt him as a ******* son and cause friction with his wife?
Imo, Lyanna is the only one that makes sense. First, Jon looks like a Stark, not a Reed, not a Baratheon, nor a Dornishman. Second, Ned never remembers anyone else extracting a promise from him, ie Howland saying, "Promise me, Ned. Take my ******* son away so he won't grow up a frog eater."
Third, Ned was always about fulfilling his duty... in this he was like a Tully. Ned dutifully fostered with Jon Arryn at the Eyrie. Ned dutifully followed Robert in the rebellion and did not press any claim to the Iron Throne. Ned dutifully wedded and bedded Brandon's bride after Brandon's murder. Ned dutifully did not slay Jaime Lannister, Gregor Clegane, Amory Lorch, nor Tywin Lannister because of Robert's commands. Ned dutifully took up the lordship of the North and the position of Warden. Ned dutifully waged war on Balon Greyjoy and took Theon as hostage. Ned dutifully executed traitors, renegades, and turncloaks with his own hands. Ned dutifully accepted the postion of Hand.
I'm not saying Ned was an automaton. His conscience guided him in matters duty, love, honor, family, politics, and war. But with his beloved sister (I get the feeling that Lyanna was the one that held Rickard, Brandon, Ned, and Benjen together) on her deathbed, would Ned consider her last wishes of paramount importance. Would he have had the courage to refuse her? He certainly did not have the courage to refuse Robert on his deathbed. He let both of them die in peace, rather than cause them further anguish. In both cases, he took the burden of facing the truth and bearing the heavy burden upon himself.
If Robert + Lyanna = Jon, why did Robert not take the only piece of Lyanna he had left to King's Landing? If Ned and Jon Arryn talked Robert out of this, why does Robert not wish back fondly on Lyanna's son when he talks of how much he dislikes his own sons?
If Rhaegar + Lyanna = Jon, then we have another possible head for the dragon, we have a reason for Ned's use of Wylla, we have reason for Ned's deception towards his wife, and we have reason for Ned letting Jon go to the Wall. Ned knew the Wall and it's brotherhood well. He knew Maester Aemon served there.
I can picture Ned thinking that the last Targaryen ******* could serve honorably defending his old kingdom. Declaring Jon's true parentage to Jon, could only bleed the realm and end in the death of Jon (Ned's foster son) or in the death of Robert (Ned's childhood best friend). I see Ned think that letting Jon believe he's a half-Stark is alright... it is the truth, if not the whole truth.
