Ewen Keenan while rescuing Elizabeth Webber from Dr. After Susan's murder, Alan took Jason home to be raised under his roof. Initially, Monica was reluctant to welcome the motherless child into her home, but she eventually grew to love him deeply. In , Jason returned home from boarding school and took his place in the family fold.
Before long, Jason became involved with fellow classmate Karen Wexler. She was a troubled young woman with an alcoholic mother and a secret life as a stripper in Sonny Corinthos' club. Their relationship ended, and Jason found new love with Keesha Ward.
Their relationship flourished until one tragic night. Intent on stopping A. The accident that followed left Jason with permanent brain damage and no memory whatsoever of his family or of Keesha.
After the accident, Jason couldn't stand the way people looked at him, always hoping to see some glint of recognition in his eyes. He pushed both his relatives and Keesha away, went to work for mobster Sonny Corinthos, and changed his name to Jason Morgan, after his adopted paternal grandmother's maiden name. The one person who was able to get through to Jason was his old high school classmate Robin Scorpio.
What began as a friendship turned into a deep and abiding love, but there was a complication: He eventually ended their affair but remained Carly's friend. Life changed for Jason again when Sonny handed over control of his empire to Jason, and Carly named Jason as the father of her unborn child. Jason knew he was not the child's father, but he agreed with Carly's lie after she confessed that the pregnancy was the result of a drunken one-night stand with A.
After Carly gave birth to her son, Jason took the child into his care when she left town, suffering from postpartum depression. Robin told Jason that she didn't believe it was right for him to keep the truth from A. Robin helped Jason care for the child, who he named Michael after his mentor, Sonny. Carly returned to town and moved in with Jason, and they briefly enjoyed parenting together until Tony Jones kidnapped Michael.
Michael was returned unharmed, but Carly shot Tony in the courtroom and was sentenced to a psychiatric care facility. While she was gone, Robin and Jason moved in together and raised Michael until Carly returned. Jason had arranged for her release, and she moved in with Jason and Robin.
This arrangement did not last long because Carly and Robin constantly argued. Ultimately, Robin left, but not before telling A. Jason did not approve of the plan, but he realized how deeply he cared for Carly while she was married to his brother. They made plans to be together until Carly misinterpreted a dance between Elizabeth and Jason, and she retaliated by sleeping with Sonny. Jason found them together and left town. He returned briefly a few months later and learned that Sonny and Carly had entered into a relationship, and he gave them his approval.
Jason returned about a year later and began dating Liz Webber. He also followed Sonny's order to keep watch over Sonny's sister, Courtney Matthews, who was married to A. She had a stalker, and Jason helped determine the stalker was actually her husband.
Jason and Courtney developed feelings for one another, and once they were both free, they started dating in secret because they feared Sonny would not approve. The longtime bickering friends married so they wouldn't have to testify against each other. The charges were eventually dropped, and the couple annulled their marriage.
Then Courtney and Jason got engaged. On the day Courtney and Jason planned to marry, a pregnant Carly was kidnapped. Jason suspected that Sonny's half-brother, Ric Lansing, had taken her, but it was months before Jason obtained proof that Ric had Carly.
By that time, Luis Alcazar's brother, Lorenzo, had kidnapped her. To appease Lorenzo, Jason and Sonny began running drugs through their operation, per his orders, all the while planning to free Carly. Unbeknownst to Jason, Courtney discovered she was pregnant. She kept the news to herself because of his ambivalence about having children during such a dangerous period.
Luis took Courtney and exchanged her for Carly, but Courtney managed to escape. In the process, she miscarried. Jason and Courtney finally exchanged vows during a trip to France, but their married life got off to a rocky start with little privacy and little time for just the two of them. When Carly lapsed into a coma after she was accidentally shot by Sonny while giving birth, Courtney took care of Carly's children, and Jason took care of Sonny's business.
Courtney became increasingly intolerant of the violence in their lives, and she and Jason separated. Courtney and Jason were continually pulled together by their involvement in the lives of Sonny and Carly, and they did not immediately file for a divorce. Ric used the crisis as an opportunity to remove Jason from Sonny's life and arranged for Jason to be handcuffed inside the burning building.
Nikolas Cassadine found Jason and saved him. After the brush with death, Courtney and Jason reevaluated their relationship, but Jason realized that a life with Courtney was not meant to be after she knocked Jason out to prevent him from killing Alcazar. They finalized their divorce, and Jason learned that Sonny's ex-mistress, Sam McCall, was pregnant with Sonny's child. Sonny and Carly had just reconciled, and Sam planned to give her child up for adoption.
Jason volunteered to help Sam and allowed her to move in with him; he offered to take care of her and the baby. While Sam and Jason adjusted to living together, Carly remained suspicious of the claim that Jason had fathered Sam's child and believed that Sam was hiding something. Carly uncovered that Sam was wanted for murder in Florida and that she had been convicted of setting her mother's house on fire while her mother had been inside.
Jason eventually discovered that Sam was covering for the person that had accidentally set the fire, her mentally challenged brother. Sonny arranged for the charges to disappear, and Jason found a specialized facility for Sam's brother to reside. The rest of Sam's pregnancy continued relatively quietly until Sonny asked her to induce her labor early so that Sonny's other daughter, Kristina Davis, could use the unborn child's stem cells to cure her leukemia.
Sam refused the request, but later went into premature labor after a heated argument with Kristina's mother. Sam was rushed to the ER, but the baby was stillborn. Sam remained unconscious after the birth, and Jason was the only person to hold the baby. When Sam awoke, Jason informed her of her baby's death and helped her understand that the baby's death had been no one's fault and that the baby's life did mean something, because her stem cells had saved Kristina's life.
As Sam began dealing with the loss of her daughter, she and Jason grew closer. They made plans to marry, and they met a pregnant teenager and believed they would be able to adopt her child. However, the young mother changed her mind and took her child back. Soon after, Faith Roscoe kidnapped Sonny's three children. Sam and Jason worked together and tracked A.
Soon after the fall, A. Sam encouraged him to see a doctor. As the incidents increased in frequency, a desperate Jason resorted to taking experimental drugs -- despite the threat of serious side effects, which included death.
While the drugs helped Jason begin to recover memories, his health quickly declined. Sam turned to Robin for help. Robin had become a leading researcher, specializing in experimental drug therapies, but Jason needed surgery. Robin arranged for Patrick Drake to go to General Hospital and perform a high-risk surgery. It was a gamble that paid off.
Jason made a full recovery, much to Sam's delight. Their love was stronger than ever, and they looked forward to a happy future. Unfortunately, Manny Ruiz stood in the way. Manny Ruiz, the homicidal son of a mobster, was instantly obsessed with Sam McCall. Manny shot Sam while she was in Jason's arms. While Sam lingered in a coma, fighting for her life, Jason convinced himself that the only way to really love Sam was to let her go so that she would never again be hurt by the violence in his life.
Sam emerged from her coma but was deeply hurt by Jason's decision to walk away from her. She turned to alcohol and engaged in a one-night stand with Ric. Unbeknownst to Sam, Jason saw her and Ric together. He returned home and started drinking until Elizabeth stopped by to visit. Jason reached out to Liz and kissed her.
One thing led to another, and they spent the remainder of the night making love. By the next morning, both realized that a relationship would never work. The next day, Jason and Sam each confessed what they had done but decided to forgive each other and give their relationship another chance.
Soon, however, Elizabeth realized that she was pregnant. It turned out that the condoms that she and Jason had used were recalled by ELQ because they were faulty. Jason asked Elizabeth to marry him if the baby turned out to be his, but Elizabeth turned down the proposal. She didn't think their marriage could work because they both loved other people.
A paternity test revealed that Jason was the father, but Elizabeth decided it was best for everyone to believe that Lucky was the father instead.
Disguised as one of the gunmen, Jason did nothing while his father, Alan Quartermaine, suffered a massive heart attack. The gunmen forced Emily to make the choice between releasing Elizabeth, who was experiencing painful contractions, or getting Alan medical attention.
Elizabeth told Emily to choose Alan, who was allowed to leave.
