Parenthood Exclusive: John Corbett Returning For Major Arc

Sarah’s (Lauren Graham) about to get some juicy new material for her next play: John Corbett is returning to Parenthood as her recovering alcoholic ex Seth for a multi-episode arc, TVLine has learned exclusively.

His comeback coincides with the return of Jason Ritter as Sarah’s on-again, off-again boyfriend Mark, setting off what exec producer Jason Katims describes as a very complex triangle.

“Just when everything seems to be going well between Sarah and Mark, Seth shows up and he’s kind of in a darker place than he’s been,” Katims explains. “And so you see Sarah really having to struggle with wanting to help him and be there for him, but also at the same time [be fully present] in this relationship with Mark that’s really good and healthy.”

Katims says he was inspired to bring Corbett back after he “did such a great job with the role” last season. “Even though there’s so much pain in the Sarah/Seth relationship, there’s also a lot of love still there,” he adds. “So this year we wanted to do a story that sort of takes that relationship to another level.”

Corbett is coming off the final season of Showtime’s United States of Tara.
