The fifth and final season of Ghost Whisperer, an American television series created by John Gray, commenced airing in the United States on September 25, 2009, concluded May 21, 2010, and consisted of 22 episodes. The series follows the life of Melinda Gordon (Jennifer Love Hewitt), who has the ability to see and communicate with ghosts. While trying to live as normal a life as possible—she is married and owns an antique store—Melinda helps earthbound spirits resolve their problems and cross over into the Light, or the spirit world. Her tasks are difficult and at times she struggles with people who push her away and disbelieve her ability. In addition, the ghosts are mysterious and sometimes menacing in the beginning and Melinda must use the clues available to her to understand the spirit's needs and help them. Ghost Whisperer'''s fifth and final season aired in the United States (U.S.) on Fridays at 8:00 pm ET on CBS, where it received an average of 7.78 million viewers per episode, becoming the least watched season of the series. Plot In the fifth season, five years have elapsed since the events of the previous season, and we are introduced to Jim and Melinda's son, Aiden Lucas. We learn that he can see the "Shinies and the Shadows", two opposing groups of ghosts that Melinda is unable to see. The Shadows are revealed to be the negative part of spirits that get left behind when they cross over, and their motives involve acquiring the Book of Changes. Melinda, Ned, and Eli, with the frequent help of Delia, work to keep the book safe from the Shadows. Throughout the season, Melinda struggles to keep Aiden safe and help him with his gift. He has frequent run-ins with the Shinies, who are presumed to be the kind group of spirits and are attracted to shiny objects. The Shadows show tremendous power throughout the season, forcing President Bedford, the president of Rockland University to blow up Delia's real estate office. At the end of the series, Melinda and Jim try to protect Aiden by convincing him that ghosts don't exist (at the advice of Carl the Watcher, later revealed to be under the influence of the Shadows). The Shadows gradually begin to take possession of Melinda's body. Aiden is told by Carl that he must go to Melinda's store. Jim, Ned, Eli and Delia follow with him.
