Professor Payne reunites with his ex-girlfriend, Nina, who is presumably in Grandview on business. After they go out, Payne is surprised to discover that Nina has a brilliant young son, Elliot. After some quick math, Payne deduces that the boy may actually be his son, a theory that Nina quickly confirms. She tells him she never knew how to tell him about Elliot, but now she needs his financial help to get Elliot in to a school for the gifted. Melinda, feeling something isn't quite right, does some sleuthing and discovers that Elliot is not Payne's son, and demands that Nina tell Payne the truth. Busted, Nina comes clean, but insists that the money really is for Elliot's education. Throughout all of this, Payne's dead wife, Kate, comes back to haunt him, demanding that they address their unfinished business so she can finally cross over. Ultimately, Payne forgives his wife for cheating on him in life, she forgives him for putting off having a child, and he decides to help Elliot with school, despite Nina's deception.
