Jack offers to show Jenny around when Jenny arrives in town from Indiana. Despite Janet's distrustful concerns, Jack is on his best behavior in showing Jenny around town, a complete gentleman. However, things take a turn when Jack, having been relocated to the couch rather than his own bedroom, takes some medication before sleeping and accidentally winds up back in his own bed with Jenny! After Janet blows up in anger at Jack, she and Jenny argue about big sis Janet being overprotective of her and not trusting her; they eventually make amends, and the misunderstanding about Jack being in bed with her is sorted out and cleared up before Jenny leaves for Indiana again.
