Delia Banks joined the main cast of Ghost Whisperer at the start of season 2. She and her teenage son, Ned, lost their husband and father Charlie three years prior to their appearance on the show. Delia became a real estate agent after Charlie's death. The character is portrayed by Camryn Manheim.
Delia meets Melinda Gordon after Melinda calls Delia about Ned having tried to shoplift from Melinda's antique store. Delia tells Melinda about how stressful her job as a real estate agent is, so Melinda offers her a job to help work at the antique store, which Delia accepts. They begin a friendship, though Delia does not know about Melinda's gift at first. In the episode "Delia's First Ghost" Melinda has to tell Delia about her gift because Charlie's spirit is haunting her. At first Delia calls Melinda crazy, admitting that she had seen Melinda talking to herself and was worried. Delia even goes as far as to tell Melinda not to expect her at work again. By the end of the episode Delia learns, with Melinda's help, that Charlie is only haunting her because he wants her to be safe. While still a little skeptical of Melinda's gift, Delia tells her that she will open the shop the next morning.
Delia remains skeptical concerning Melinda's gift in season three, but discusses the various ghosts that Melinda encounters to help Melinda with them. When Melinda was stalked by a lawyer, Shane, he tampered with Ned's records because Delia was trying to get him into private school. Nevertheless, when Shane was caught Ned's records were untarnished and Ned got in. In episode 5, "Weight of What Was", Delia travels along with Jim and Rick into a series of underground tunnels and alleyways from a much older Grandview to find Melinda. With the help of a ghost named Tessa, they manage to locate her and get her to safety. In "Bad Blood", Delia's need to find a rational explanation for every situation, including ones involving ghosts, is brought up. Delia tells Melinda that she will try harder to accept the notion of ghosts. In the episode "Heart and Soul", Delia's need for a rational explanation nearly destroys her relationship with Melinda, but a conversation with her son and a moment with "Sam" at a basketball court provides her with faith in Melinda's gift. She now believes that Jim is living in Sam's body. Sometime between season 4 and the 5 year leap she opened a ester building next to Melinda's shop.
