In the eighth season of Seventh Heaven Lucy (Beverley Mitchell) and police officer Kevin Kenkirk (George Stults) begin life as a married couple but their relationship is threatened by the arrival of Kevin's contentious ex-wife, Mindy (Mindy Burbano) in "Peer Pressure." Mary (former series regular Jessica Biel, now a "guest star") reveals her own recent marriage to Carlos Rivera (Carlos Ponce) in "An Early Fall Part 2." "A Long Bad Summer Part 1" finds Simon Camden (David Gallagher) dealing with the fallout of a fatal car accident he was involved in. Matt Camden (Barry Watson) weathers his first year of internship in a big-city emergency room in "The One Thing." Elsewhere, the relationship between youngest Camden daughter Ruthie (Mackenzie Rosman) and troubled preteen Peter Pietrowski (Scotty Leavenworth) hits a snag when Peter's birth father, Vic (Bryan Callen), comes back into his life in "The Prodigal Father." Season eight ends with a two-part episode, "Little White Lies," wherein one couple considers breaking up, another tries to get back together, a third contemplates leaving Glen Oak for good, and yet another member of the Camden household prepares for motherhood.
