Joshua the Ghost, appeared in the episode "The Tale of the Jagged Sign", he was portrayed by Daniel Brochu (credited as Danny Brochu).
The time is not known, but it can be assumed at least 70+ years prior to the events taking place in "The Tale of the Jagged Sign", Joshua was in a
loving and committed relationship with his girlfriend Marjorie. He once gave her a beautiful music box, it was two doves sitting together on a tree branch. Also he made a symbol of a dove like angel as a sign of their love.
He and Marjorie used to climb the mountains in the nearby woods. There they would have privacy and hang out quietly in the secret place at the top of the cliff. He and Marjorie wanted to marry, but since they were still so young at the time their parents wouldn't allow them. He and her made a plan to meet one morning at their secret place. Then they would make their plan to run off together and get married.
Marjorie's parents somehow found out and stopped her from going. Joshua was hurt and believed she chose not to come, so he wanted everyone to know how much he loved her. So he climbed up to the ledge at the top of the cliff. Then he began to draw the symbol of their love for everyone to see. The cliff was too steep and dangerous and before he could finish drawing the symbol, he fell down. He died thinking she chose not to come and rejected him.
People living in the country, started a rumor that the place used to an ancient burial ground. They would say that years someone was murdered there and the sign just appeared the next day. They also said that the unfishined sign he drew was the jagged sign; a sign and mark of the dead man. If one was to stare at it for too long they would awaken the ghost and it would possess them and then lure them up and have them fall to their doom. Joshua was seen at the top of the mountain. Possibly he haunted the the cliff on top, and was still waiting for Marjorie to show up. He was seen often enough for people to believe him to be the ghost.
One day in the 1990s, many years later two girls named Claudia and Kate climbed near the top of the mountain. When they got there Joshua mistook Claudia for Marjorie. Then he started waving for her to come over to him, and wherever he could he would draw the jagged sign thinking it would get her to return to the cliff.
Around this time Marjorie has grown very elderly and her health and her memory was beginning to fail her and was soon to be headed for a nursing home.
One night he was seen outside in the cold night air, he frosted up Claudia's window and made the jagged sign draw itself on the window. When she looked out he waved for her to come over to him again. When she didn't he illuminated with an aura and then vanished. Possibly he was partly an angel or an apparition now but it's uncertain.
Eventually Claudia and Kate climbed to the top of the cliff, when he saw them he finally spoke and asked Marjorie what took her so long to meet him and asked her whether or not she loved him. Kate revealed the truth to him and explained why Marjorie never showed up and told him him she kept the music box all these years and still loves him.
His heart was touched to find out she still loved him. Then on Kate's advice he decided to go see her and declare his love for her. Doing this his Jagged Sign symbol completed itself to represent a dove like angel. Just as he meet with her, she passed away. Then their young ghosts walked off together in the woods, he and her waved goodbye to Claudia and Kate and vanished. Then it was assumed that he and her ascended into the afterlife.
