In Season 1, Alan and Evelyn get along better. It is Season 2 that there relationship becomes much like Charlie and Evelyn's. Evelyn has mentioned on several occasions that Alan was always the 'good son'. In "Castrating Sheep In Montana", Evelyn tells Alan that they were through, but that didn't last long. In "Nice to Meet You, Walden Schmidt", she tells Alan he's going to move in with her. Although she says on several occasions that he can't (After he moves back into the beach house, too; I Changed My Mind About the Milk, I Think I Banged Lucille Ball).
