It's interesting. Martin layers symbolism and foreshadowing very thick. My tip has always been the direwolves, who are pretty sure indicators of what will happen to their Stark. I think of Arya and the way her wolf was "driven away." I think of Sansa and Lady being sacrificed, basically, to the Lannisters. Bran's wolf being kept isolated... etc.

Jon has the only white wolf, and it was found "after the fact." White, to me, was a big hint at the Targaryens. If you remember, Ghost also matured faster than the other direwolves. He's quiet-- doesn't make sounds-- which indicates secrets, to me. Even his name references what remains after death (Jon's parents).
