Nikolas took a job painting a church, and ran into Lorenzo Alcazar, whom he couldn't remember. Lorenzo offered "Connor" a job, knowing full well his true identity.

Connor and Mary became engaged and renewed their vows in Mexico, a place Connor was attracted to for some reason.

Emily was there at the same time and saw him. She confronted him and realized that Nikolas believed that he was Connor. She didn't tell him anything.

However, Nikolas was disturbed by memory flashes and underwent hypnotherapy. Attracted to Emily, he made love to her. He returned to Mary after she tried to kill herself.

When Emily learned that Mary was trying to become pregnant, she threatened to tell Nikolas the truth. Mary lied to Nikolas about Emily's place in his life, portraying her as an ex-girlfriend still obsessed with him.

When Nikolas found out the entire truth, he was angry with Emily for not cluing him in. She confessed that she didn't want to drive him away. He felt betrayed.

Nikolas is Institutionalized

Now Nikolas knew who he was, but he still couldn't remember anything. Helena had him committed so he could be declared incompetent, and she could get her hands on his fortune.

She had him continually drugged in the institution; she also he did the same thing to Emily. Nikolas saw Emily and the two escaped.

Before they did, Nikolas had a sudden jolt, so strong that he leaned against the door and started to slide down to the floor.

As he did, he remembered his entire life. He and Emily were finally together, or so they believed.

Mary's real husband, Connor Bishop, the Nikolas lookalike, in fact was not dead as thought and surfaced in Port Charles.

Like Mary, he was somewhat deranged, and before Nikolas knew it, Connor became involved with the couple after Helena's "death" over a cliff on Nikolas and Emily's wedding day. 

Nikolas claimed it was self-defense. Connor blackmailed the couple, because he knew that Nikolas threw Helena over a cliff after he got the knife away from her. His plan fell apart when Nikolas confessed what happened to the authorities.

Everyone Goes to Prison; Emily is Attacked; Nikolas and Courtney Hook Up

Connor went to prison. So did Nikolas, but not before he and Emily married and shared a beautiful night together. Nikolas received a harsh sentence of life without the possibility of parole.

Desperate to free him, Emily, knowing that Helena was still alive, decided to flush her out by getting Connor Bishop to pose as Nikolas. She found Connor and he agreed to help, in part because of his interest in Emily.

Emily coached him in all things Cassadine; in the course of events, Connor raped her. Helena came out of hiding, and Nikolas went free.

Unable to handle the rape, and refusing psychological help, Emily was unable to make a go of her marriage to Nikolas.

Nikolas found solace with Courtney Jacks, who was going through unhappiness in her own marriage to Jasper Jacks. Elizabeth Spencer was carrying their child, and Courtney was feeling left out.

Courtney and Nikolas fell in love, and she and Jacks divorced. When she conceived a baby, Jax believed the child was his and wanted a paternity test. He bribed the technician to change the results in his favor.

Ultimately, the child turned out to be Nikolas', and he named the child Spencer. Courtney later died of a virus.

The MetroCourt Crisis; Emily Dies; Nadine

Eventually, Nikolas and Emily reconciled. After the MetroCourt crisis, during which Emily's father Alan Quartermaine died, the perpetrator, Mr. Craig, actually Jerry Jacks, injected Nikolas with a poison.

Craig held the antidote. He wanted Nikolas to help him get a new identity and set him up in a new life. Nikolas had no choice but to agree.

Robin, Patrick, and Emily searched for the antidote, finally locating it and giving it to Nikolas when Jerry Jacks was away. It worked. Nikolas made a complete recovery from the poison. Or had he? He began to go through memory loss and rages, though infrequently at first.

On the night of a huge ball Nikolas threw at Wyndemere, a storm occurred. The guests could not leave, and there was a blackout.

The guests began to be murdered systematically. Nikolas was searching for Emily, and they finally found each other in the ballroom. Nikolas was knocked unconscious, and when he came to, Emily was dead.

Devastated, Nikolas later began to have visions of Emily and was able to speak with her. He later learned that he had a brain tumor. It could be removed by surgery, but with the removal, he would no longer be able to see Emily.

Nikolas was sorely tempted not to have the surgery. With the help of a nurse, Nadine, he finally agreed to it. He and Nadine had a brief involvement, but in his heart, he was still in love with Emily. Nadine wanted more, so the couple broke up.

Emily: The Sequel;The Nikolas-Elizabeth Affair

Then Nikolas was faced with Emily: The Sequel. She had been rescued during a terrible fire at General Hospital.

Unlike Emily, she wore heavy eye makeup, and seemed earthier than Emily. Her name was Rebecca Shaw.  Nikolas' aunt, Alexis Davis, was certain that Rebecca was a plant of Helena's. Nevertheless, Nikolas fell for her.

In truth, Rebecca was Emily's twin sister, separated from her at birth.  She was in Port Charles on purpose.  She and her lover, Ethan Lovett, were after the Cassadine and Quartermaine money.  They planned to use everyone's grief over Emily so that Rebecca could get her hands on their assets.

Rebecca was supposed to seduce Nikolas, but the heart wants what the heart wants, and she liked Lucky better. Nikolas and Elizabeth were jealous, and one night, they kissed so that Lucky and Rebecca could see them. 

Eventually Elizabeth reconciled (again) with Lucky, and Nikolas and Rebecca got together. Rebecca fell for Nikolas and broke up with Ethan. Lucky learned about their scheme and told Nikolas, who played dumb and then dumped her. 

In truth, he hadn't stopped thinking about Elizabeth since they kissed. Rebecca left Port Charles and met a new man on the plane.

The feeling was mutual as Elizabeth fell back on an old pattern of wanting whomever she wasn't with -- this time it was Nikolas. They began to see each other in secret. 

When Lucky found out, he was destroyed and ended his engagement to Elizabeth. Nikolas and Elizabeth, filled with guilt, stopped seeing one another.

Elizabeth became pregnant, and Helena figured out that Nikolas could be the father. Though the father was Lucky, Helena paid off a lab technician to list Nikolas as the father.

What revenge!  To have a Spencer raised by a Cassadine.  When Aiden was born, Nikolas and Elizabeth endeavored to get along for the boy. Their relationship had become uncomfortable due to Lucky's anger. 

Brook-Lynn Ashton is Hired by Nikolas

When Brook Lynn Ashton returned to town, Nikolas hired her as an escort to attend business functions with him. Elizabeth was horrified when that platonic relationship became sexual. It didn't last long as Brook again left Port Charles to pursue her on and off music career. 

Tragedy struck when Elizabeth and Lucky lost their son Jake in a hit and run. Elizabeth finally told Lucky that Aiden was his son, which Nikolas refused to accept. 

He was so upset that he left town with his son Spencer.  He wanted to pursue a life of his own, away from the ubiquitous Cassadine-Spencer feud.  He and Lucky patched things up and said a heartfelt goodbye.

When his sister Lulu was kidnapped, Nikolas returned to Port Charles.  As he was trying to explain to Luke and Laura what he knew about the kidnapping, he was shot in the chest and required surgery. 

When he was finally able to talk, Nikolas revealed that his father, Stavros, was alive and came after Lulu.  Helena had saved Stavros after his second death and placed him in yet another cryogenic chamber, on Cassadine Island, to bring him back. 

Nikolas, on learning that Stavros was alive, played nice to get some information regarding his plans. Stavros wanted Lulu.  Nikolas left the island and returned to Port Charles to warn his family. 

But he was too late. Stavros had already taken her. Lulu was rescued, and Stavros killed for a third time.

Nikolas found that he was still in love with Elizabeth, but she wanted to move on.  She was beginning a relationship with A.J. Quartermaine.  Nikolas was determined to win her back.

Tracy Quartermaine was fighting A.J. for control of ELQ and offered to team up with Nikolas against A.J.  He agreed.  It didn't last long because Nikolas realized that Elizabeth really wanted to be with A.J. 

Nikolas decided to move on from Elizabeth. Then he met the beautiful Dr. Britt Westbourne, a pregnant, single woman.  The father of her baby, whom Nikolas believed to be Patrick Drake, was not involved with the pregnancy.

Nikolas had Britt move into Wyndemere so she could receive good care during her last weeks of pregnancy.  She admitted that she had lied about the baby's paternity. 

Nikolas was angry but before he could throw her out, she went into labor!  He forgave her and had her stay at Wyndemere. They grew closer, even after he found out that her parents were Dr. Liesl Obrecht and Cesar Faison.  

The way Nikolas figured it, they both came from rotten families. That gave them something in common.

When her baby, Ben, was kidnapped, Nikolas went after the kidnappers. That's when he found Robin Scorpio still alive.  She had been taken by Jerry Jacks and Britt's parents. 

Faison, Liesl, Britt, Robin, and Nikolas all wound up together at Wyndemere, with no one to know that Robin was alive until she finished putting together a serum to cure Jerry Jacks of plutonium poisoning. 

That ordeal at last was over, and Britt and Nikolas were a couple and even became engaged.  He found out soon enough that Britt's baby belonged to Dante and Lulu; Liesl Obrecht had stolen one of their embryos.

When he found out, it did not go well for her.  Britt and her father eventually left Port Charles. And with her mother now Chief of Staff, anything is set to happen.

Nikolas is now in the clutches of Hayden, who came to Port Charles pretending to be the wife of Jake, who is in reality Jason Morgan. She was exposed at the 2015 Nurses Ball.

Despite the fact that Nikolas wants nothing to do with her, he can't stay away from her, and the two of them are engaged in a heavy sexual relationship.

Hayden knows the truth about Jake, and she knows that Nikolas knows, too, and hasn't told anyone.  It's time for a little blackmail. Hayden knows what she wants. And it's the hunk in bed next to her, the one with the estate, the title, and the money.

We'll see what happens next.
