BROTHERS AND SISTERS is going to look very different this fall. In addition to the already announced cast departures of Rob Lowe (Robert McCallister) and Emily VanCamp (Rebecca Harper, who will appear in several episodes to wrap up her storyline), Michael Ausiello of Entertainment Weekly says sources confirm that Balthazar Getty, who has played Tommy Walker throughout the series, will not be returning to the show. Getty was in a reduced number of episodes last season and his departure is being billed as a “creative decision.” Tommy’s absence will be explained in the fifth season premiere, which will be set one year after the tragic events of last season’s finale.

The season premiere of Brothers and Sisters is Sunday September 26 at 10pm/9 central on ABC.
