According to TvLine, Jason Ritter is will reappear in the Parenthood series.
Ritter, who has come and gone for a few episodes, was last seen at the end of the fourth season of the series.
In that episode, Mark (Ritter’s character) was left out because Sarah (Lauren Graham) made her choice between two romantic interests, her fiance (Mark) and her boss, Hank (Ray Romano). Sarah chose her boss, but at the beginning of the fifth season, their relationship ended.
The actor will come back in the 19th episode of Parenthood, which will air on April 24. For now, he is only scheduled to appear in that episode.
