'Parenthood': Jason Ritter will return late in Season 5
Jason Ritter will return to the NBC drama late in the season to reprise his role as Sarah's ( Lauren Graham) ex-boyfriend, TVLine reports. He last appeared in the Season 4 finale, when Sarah had to make a choice between him and Hank ( Ray Romano).
Ritter then went on to FOX's "Us & Them" opposite Graham's former TV daughter, Alexis Bledel. That show has wrapped filming after having its episode order cut, thus freeing him up to return to "Parenthood."
Mark will appear in the season's 19th episode, which will air in the spring. He comes back into the Bravermans' orbit via a chance meeting with one of the show's regulars -- whether that person is Sarah or someone else remains to be seen.
