On the verge of her wedding to Jim, Melinda is visited by a ghost that may endanger her baby, in the May 15 season finale of 'Ghost Whisperer'.
It is time to wrap up "Ghost Whisperer" with the season finale on May 15. In "Book of Changes", wedding bells ring for Melinda and Jim. But when a ghost pays Melinda an unexpected visit, she worries for her unborn baby.
The significant of the Watchers will be revealed in this episode. Show runner P.K. Simonds explained previously how the Book of Changes relates to their abilities, saying "Over the very, very long span of time that they've been watching, (the Watchers) have observed that history tends to repeat itself."
"That gives them a certain ability to make a pretty good educated guess about what the future is. They are able to know something about what's taking shape, let's say, in a character's womb. And yes, it's possible to know certain things about the gift that might be growing."
It had been revealed that Melinda's baby will play a huge role as her "apprentice" for the fifth season.
