The Catcher in the Rye Edit
During Pencey's match against Saxon Hall, Stradlater goes on a date with Jane Gallagher, a childhood friend of Holden. He also asks Holden to write a descriptive composition for him for his English class.
When Stradlater returns from his date, he tells Holden how he and Jane ended up in the car he had borrowed from coach Ed Banky, though he does not give much detail about it. In a seemingly fit of jealousy knowing Stradlater does not value Jane's character as much as he does, Holden instigates a fight where the two end up bloody.
According to Holden, Stradlater is a "Year Book kind of handsome guy" who has a good build, with broad shoulders and practically the same height as Holden (6'2½"). Stradlater is described as a "sexy bastard" who has a way to charm girls that Holden had personally known two girls to whom he has given the time to. Holden also mentions that he always walked around their dorm room in his bare torso, and that he was madly in love with himself.
Although vain in his appearance, Stradlater is a "secret slob", according to Holden:
One redeeming quality Stradlater has Holden mentions is that he can also be very generous "in some things".
