Gillian Sveck is James' sister. Gillian is a college student who is gullible and allows herself to model the behaviors of those she admires, especially her language professor. Gillian and James are not particularly close as Gillian is self-centered and seems to be most concerned with her own problems. However, Gillian is only one of a few that James feels comfortable around and sharing his feelings with. Gillian too seems concerned enough about James that she does offer some advice about college to him.
