S4E25 Strange Bedfellows (2)

As Sam and Janet's bond deepens, Diane's jealousy intensifies. Janet proposes that Sam let Diane go to completely cut ties with his past, but Diane catches wind of this and resigns before he has the chance to dismiss her. Meanwhile, Vera's sister Donna is in town, and Norm is anxious that she might flirt with him again, just like she did during her previous visit.
