besides if brandon + ashara really equaled jon, there would be no reason for ned to hide him from robert to the point where he dishonors his own name.
Good point.
Ned doesnt hide Jon from Robert though, he just doesnt entertain small talk about his baby mother.
The flaw in that for me if that he seeds Ashara up before his brother dies why hide it? Brandon was supposed to wed Cat. It could be that he loved Ashara, who killed herself.
So he either doesn't lie, and/or will not free himself from the lie by snitching on his brother.
Or dishonoring both the name of the dead women he loved or the mother of his northern children. This ties in with Neds character and involve being honorable on all counts
Another indicator often overlooked are the Direwolf pups they found, who are all siblings, for all the Stark siblings, aint no cousins of the Starks running about with Direwolves.
We know Ned is haunted by the promise of protecting a child and feeling he failed, how can this have anything to do with Jon,??
Ned isnt worried about Jon at all, defo no where near enough to be haunted in the way he clearly is in the first book. So it doesnt make sense that Jon is Lyanna's boy. Even if Jon is Brandons which I also doubt, Ned cosigned for Jon to go make a lifelong pledge to Nights Watch with his bad ass First Ranger Uncle, so is just moving from one Uncle to a next.
Jon is Neds son, Ned aint losing no sleep over Jon. Ned raised Jon, at Wintefell. The kid is about that Winter Life Jon can look after his self, oh yeah and has his own fukkin Direwolf.
But if Dany is his niece, think about it. He thinks of the promise he made to Lyanna when in the crypt with Robert, on the way to Kings Landing and more than once haunted by the whole thing whilst at Kings Landing, especially after the big argument with Robert and the council over
killing Dany.
