Ryan's ex-fiancee Annie and ex-best friend Mark return to town, married. On the surface, they seem to want to apologize and bury the hatchet but their actions reveal other intents. For Ryan's sake, while promoting true forgiveness, Cassie continues the ruse of being his girlfriend. As a gas leak moves the town ball to Gray House, John remains nervous about revealing his relationship to Ashley, Anthony (earlier catching Nick and Grace together) successfully dupes Nick into thinking Grace spilled his secret to him, and Sam (confused by Cassie and Ryan's resent actions) allows Stephanie to presume his romantic interest in her.
