Sarah Braverman isn't done with Mark quite yet.

According to TVLine, Jason Ritter will return for season 4 of "Parenthood" as Mark, Sarah's (Lauren Graham) love interest after Season 3 of the series ended in Mark proposing to Sarah.

“As far as I understand, they want to keep me around, and we’ll do as many episodes with me as we can all do,” Ritter told TVLine of the NBC series, adding that won't be a series regular. "There are so many regulars that I think that they would probably drop people before they’d add people."
