Ghost Whisperer Episode 4.08 Heart & Soul

At the hospital, Melinda stands vigil by Sam Lucas, the man whose body Jim inhabited after watching his soul cross over. While Jim's interference allowed "Sam" to survive his accident with minor injuries, neither of their memories are present in "Sam" now. Melinda is certain that given the time, Jim will regain his memories in Sam's body, allowing them to be together again. Eli and Delia start to worry that Melinda is losing her grip on even the bizarre reality they all share, and Eli reminds her that even if Jim did inhabit Sam's body, memories generally don't survive the transformation of either reincarnations or "walk-ins." Undaunted, Melinda continues to spend time with Sam, who will almost always appear on screen as Jim.

When Sam and Melinda start to put the pieces of his old life back together, Melinda must help convince his parent that he needs to follow his own instincts to regain his life. She must also cross over a ghost who witnessed Jim "steal" Sam's body, which she does by helping Sam's family. Finally, Delia is truly convinced that Jim is in Sam's body, after she runs in to him at an appointment only Jim would keep. In order to keep Sam close and give him a reason to stay in Grandview, Melinda offers him a job renovating and living in her garage.
