Mr. Spencer - Holden's history teacher lectures Holden after getting kicked out of Pencey. He forces Holden to read his final exam essay, symbolic of forcing Holden to face the truth. It doesn't go well.
Ackley - Holden finds Ackley's presence irritating. His presence in Holden's room torments him.
Stradlater - Holden calls Stradlater, his roommate, a secret slob. Outwardly he's different than Ackley, but in private he considers them the same. Stradlater represents the type of phony that Holden despises.
Jane Gallagher - Holden remains fascinated with Jane and fails to recognize his own cowardice in regards to calling her. He excuses himself for not calling by saying he's "not in the mood." She represents the ideal female, which stands in contrast to her going out with Stradlater.
