The sitcom's 11th season is the first without Angus T. Jones as Jake, but the Harper gene pool is a deep one as Amber Tamblyn joins the cast as Jenny, Charlie's long-lost, out-of-wedlock daughter who shares her late father's love for alcohol--and women. An aspiring actor, Jenny quickly bonds with Walden (Ashton Kutcher) and her uncle, Alan (Jon Cryer), and eventually moves into the beach house. In other developments, Alan and Lyndsey (Courtney Thorne-Smith) embark on a sex-only relationship until she starts dating Larry (D.B. Sweeney) and Alan falls for Larry's sister, Gretchen (Kimberly Williams-Paisley); Walden helps a former employee (Odette Annable) with her software start-up; Berta (Conchata Ferrell) mulls retirement; and Evelyn (Holland Taylor) gets ready to tie the knot with Marty (Carl Reiner).
