John Corbett heads back to 'Parenthood' for Season 5 guest spot
According to TVGuide.com, Corbett's Seth will appear in Episode 13 when Amber (Mae Whitman) gets into an argument with another patron at the restaurant where Seth works. It makes sense that Amber would want to reconnect with her father, especially since she's in the middle of planning her wedding.
Corbett previously appeared on "Parenthood" as the troubled Seth during Seasons 2 and 3.
"Parenthood" airs Thursday nights at 10 p.m. ET/PT on NBC.
