Do you think Ned would have tried to put AeJon on the throne after Robert was killed, had LF not betrayed him? I'm curious what his plan was before everything went to **** and he lost his head. Would he have considered AeJon his trump card so to speak?
I think by the time Robert died Jon had already taken his vows.
When you think about it, it was kind of crappy of Ned. He was only going to let Jon know he was the rightful heir after Jon foreswore all titles by taking the black. This would protect Ned from ever having to choose between Robert and his children or Jon Snow. That is great, but it completely deprived Jon of his birthright in exchange for spending the rest of his life freezing his balls off.
In the books, Ned is corresponding with Stannis and I believe his intent was to put Stannis on the throne.
