In the novel The Catcher in the Rye, why was Holden nervous about Stradlater going out with Jane Gallagher?
Holden talks about Jane Gallagher and thinks about her throughout the entire novel. He is obviously in love with this nice, sensitive girl, but he is too shy to try to win her affection--or else he has too much of an inferiority complex to believe she would be interested in him as a steady boyfriend. Holden is "nervous" about Stradlater going out with Jane because he knows Stradlater all too well. He is quite sure that Stradlater will do his best to seduce Jane, as he does with every girl he takes out on a date. Holden uses the term "nervous," but actually he feels jealous, possessive, and protective. He respects Jane too much to think of trying to seduce her himself, and he hates to think of an unscrupulous phony as Stradlater taking advantage of the girl he loves. Characteristically, Holden does not fully understand his feelings and can only think of the word "nervous" to cover a number of unpleasant and conflicting mixed emotions.
In chapter four of The Catcher in the Rye, Holden learns his handsome, popular (but tremendously irritating) roommate, Stradlater, is going on a date. Holden soon discovers this date is, in fact, Jane Gallagher, who Stradlater refers to as "Jean." Holden has feelings for Jane, whose eccentricities—like keeping all of her kings in the back row in a game of checkers—he finds endearing.
Holden is nervous about his going out with Jane because of Stradlater's sexual experience. He does not want Stradlater to make a move on Jane because he fancies her for himself (despite being too awkward to do anything about it). He also worries she cannot handle Stradlater's advances due to the fact that she may have been abused sexually by her stepfather.
Holden, overall, sees Stradlater as a big phony who only cares about getting Jane into bed and does not appreciate her for the special qualities she possesses.
Holden Caullfield does not want Stradlater going out on a date with Jane, because in Holden's mind Stradlater is a total phony. Holden perceives that Stradlater is only interested in sex, not Jane personally. Stradlater does not even know her name! Holden does, though, and cares about Jane as a friend; he guesses that Jane has possibly been sexually abused by her stepfather, and worries that Stradlater's smooth-talking ways might be too much for her to handle. Holden also wants to rescue her from Stradlater's evil clutches, because of what Stradlater is-- handsome, popular, well-built--everything Holden is not. Holden would like a relationship with Jane for himself but is too socially awkward to achieve it.
