Interesting piece of foreshadowing

[Livesundersink]

I was re-reading Game and i came across this quote in Jon's last chapter

Jon was not afraid of death, but he did not want to die like that, trussed and bound and beheaded like a common brigand. If he must perish, let it be with a sword in his hand, fighting his father's killers. He was no true Stark, had never been one... but he could die like one. Let them say that Eddard Stark had fathered four sons, not three

Considering the manner in which members of the Stark family are killed or perceived to be killed, it strongly hints at Jon's betrayal long before it occured
