Season 2
Ygritte encounters Jon Snow and Qhorin Halfhand when they capture the wildling watchpost she was at. All her fellow wildlings are eliminated, leaving her to be executed by Snow, but he cannot bring himself to do it. His hesitation allows her to escape, but Jon recaptures Ygritte, thereby separating from his brothers. With night approaching, Jon refuses to make a fire, forcing them to sleep out in the cold. Ygritte convinces him to huddle next to her to share body warmth, after which, much to his irritation, she makes sexual advances towards Jon.

In the books
In the Song of Ice and Fire novels, Ygritte is a wildling spearwife in the force led by Mance Rayder. She is described as skinny, but well-muscled with a round face and a pug nose. Her most distintive feature is her crooked teeth and her fiery red hair. The wildlings consider red hair and those who have it to be 'kissed by fire', a sign of great luck and fortune.
