Storyline
As an adult, Josh comes to Pine Valley, and Erica Kane, not yet knowing that Josh is her son, hires him as a producer at her talk show "New Beginnings". In order to steal Erica's job, Josh begins to sabotage Erica, even going so far as to drug her, and frames Amanda Dillon in his place. His devious intentions are eventually revealed, and he is fired as producer of Erica's talk show, with Erica hating him.
In late July 2006, not long after Greg has been killed, Josh finally discovers the truth about his birth at the opening of the nightclub ConFusion. He is devastated and decides to leave town. Erica tries to explain to him that she does not hate him and her reasons for making the decision to have an abortion all those years ago, but Josh does not want to listen to her.
Throughout the whole Greg Madden ordeal, Josh develops a close relationship with Babe Carey Chandler, who convinces him to stay in town. Josh gradually falls in love with Babe and has a one-night stand with her. However, despite her rocky marriage to JR, she chooses to stay with her husband, leaving Josh heartbroken and more willing to fight for her love.
Josh connects with his half-sister, Bianca Montgomery, whom he loves, but is not above using to get what he wants; however this characteristic does not faze Bianca, and it allows her to share with her older half-brother that her girlfriend, Maggie Stone, cheated on her while they were in Paris. Like most everyone else in the Kane-Montgomery family, Josh proves to be extremely protective of Bianca, especially where her happiness is concerned and is acrimonious towards Zarf/Zoe, whom he thinks would hurt Bianca.
Josh's relationship with his other half-sister, Kendall Hart Slater, though not at first as close as his relationship to Bianca, also becomes stronger. He is sometimes seen as somewhat of a protector of Kendall as well, and is able to connect with Erica at times, the two having found a certain comfort with each other.
Josh leaves Pine Valley after Babe is apparently murdered by The Satin Slayer. However, after the funeral, Babe is seen waking in a hidden room in Zach Slater's casino and Josh asks how she feels. Josh, Kendall, Zach, Joe, Jeff, and Jack, all aware that Babe is still alive, keep this fact a secret in order to keep her out of harm's way. Once back in Pine Valley, due to Josh's constant unwanted involvement in Babe's matters, Babe tells Josh to get out of her life. Some time afterward, Josh has a fling with a woman named Hannah Nichols.
Before he becomes boss at Chandler Enterprises, he is briefly involved with Greenlee Smythe. Due to having tricked the Chandlers out of their fortune, Zach is able to do what he wants with Chandler Enterprises. He names Josh as Chandler Enterprises' new boss. But when Adam Chandler regains control of Chandler Enterprises, Josh becomes the former CEO of the company.
In June 2008, he has a one-night stand with Greenlee. He leaves in September 2008 due to being cast out of the family by Zach when it is revealed that he stole money from Zach's casino. Though Josh apologizes for the theft and says that he was going to pay Zach back, Zach will not forgive Josh and makes Josh's life "a living hell" while Josh is on the run.
Josh returns on January 14, 2009. He visits with a comatose Kendall, telling her how much he loves her and that he will make Zach pay for sending him into exile. A day later, after stealing ten million dollars from the casino, he takes Reese Williams (Bianca's new lover) hostage to ensure his escape. Erica and Bianca try to talk him out of the crime, but Josh refuses. Once Reese breaks free from Josh's grasp, Zach raises his gun at Josh. Josh, in turn, raises his gun at Zach. Zach does not hesitate in shooting Josh. As Josh is dying, he professes his love for Erica and Kendall and says that he just wanted a second chance. He soon dies. Zach orders the paramedics to keep Josh's heart pumping in order to save Kendall, who needs a heart transplant. Josh is put on life support and pronounced brain dead. It is Erica's decision whether or not to let the doctors do the heart transplant. She is torn on the matter, but there is no time to spare, as Kendall will soon die. Erica gives permission for the surgery and says goodbye to Josh with Bianca.
