Jon Snow (to Ned): Lord Stark? There are five pups… one for each of the Stark children. The direwolf is the sigil of your House. They were meant to have them.

Bran Stark: What about you?

Jon Snow: I’m not a Stark.

Robb Stark: What is it?

(Jon finds another little direwolf – white one)

Theon Greyjoy: The runt of the litter– that one’s yours, Snow.
