Ghost Whisperer (season 4) (2008)

In the fourth season, Melinda meets Eli James after a fire at Rockland University who, after his own near-death experience, develops the ability to hear ghosts. Melinda says goodbye to her close friend Rick Payne, who leaves Grandview on a research trip for the university. In this season, Jim is shot and killed. He does not "cross over" because he does not want to leave Melinda, and his spirit later enters the body of a man named Sam Lucas, who died in an unrelated accident in Grandview and crossed over. When Jim/Sam regains consciousness, he has no memory of being Jim. Melinda works to get him to remember his past life and her, and succeeds after much difficulty and skepticism on the part of her friends. They soon discover that Melinda is pregnant and that the date of conception was right before Jim died.

At the end of the season, Ned and Eli find the Book of Changes, a book written by the Watchers . The book tells them of past and future prominent dates, such as Andrea and Jim's deaths. One date is listed as September 25, 2009; Melinda's due date. Melinda learns from a Watcher named Carl that her child is destined to not only inherit her gift, but be far more powerful than her. Melinda and Jim decide to remarry and have a small ceremony on a snowy night, on the street where they first met.
