You were a Robert and Cersei's daughter, a princess, it was your first visit in Winterfell. While feast in Stark's castle you sit with your family and with Starks. You were kinda bored looking around the mess hall. After some time you decited to get some air. You walk out of the hall and walk to big door. When you get there you saw someone already standing there, it was Jon Snow Ned Stark's bastard and next to him white direwolf pup.
