Eli's dad, Ray, unexpectedly dies when he's brought to the ER by Casey, his business partner's daughter. Melinda is there, dropping Jim off and runs into Evelyn, Eli's mother, who is a ghost and hasn't crossed over. Together, Melinda and Eli try to discover why Evelyn is so insistent on getting her husband into the light and why she's still hanging around. They quickly surmise that Ray was having an affair with his business partner, Anne, and, to Eli's horror, they realize that Casey and Eli might be half brother and sister, which really puts a damper on their burgeoning relationship. Upon further investigation, with the help of Aidan's drawings, Melinda is shocked to find out that when Evelyn died of a brain aneurysm she might not have been alone. Ray is insistent however that it was Evelyn who was having an affair with Anne's husband, Don and though he's forgiven her, he's angered to find out that the affair might not have been over and Don was the one with Evelyn when she died. So he begins to torment Don. At Ray's funeral, Melinda brings everyone together and the truth comes out that Evelyn was indeed having an affair but with ANNE, not Don. They would meet at their shared lakehouse and one night, when Anne went to meet her, she found Evelyn, on the floor, dead of a brain aneurysm. She didn't want anyone to suspect of their affair since there were candles and flowers around, so she cleaned everything up and ran off, calling the caretaker, pretending to be a neighbor so someone would find her. Everything is forgiven but rather than leave Eli alone and bereft, Ray and Evelyn decide to forgo going into the light for now and be there for Eli.
