Oh I know. The color of the hair has always been important to certain houses, it's sort of a branding mark for many of them (Lannisters, Targaryns, etc) so I just thought it was interesting how the one thing that made it unlikely for Jon to be Targaryen, the lack of white hair that all other Targaryens were known to have, was lived out through his dire-wolf, Ghost. None of the other dire-wolves were white haired, only the one given to Jon, which in hindsight makes much more sense now as a thematic device. Before this reveal the only thing that sort of connected was the fact his name was Snow, and snow is white, thus why he got the white wolf, but being a Targaryen changes the dynamic.
Interesting. Before the reveal, I assumed Ghost was given to Jon due to an Albino, runt's status in a pack of wolves is the lowest tier - similar to Jon's status as a bastard.
