Valentin emerged in June of 2016. He first claimed to be Theo Hart, a native of Cassadine Island and a fisherman. He quickly revealed his true identity and shot Nikolas in order to usurp the family fortune.
When he turned up in Port Charles, Valentin continued to use the name Theo Hart. He used the alias when he met and had a one night stand with Nina Reeves. For both though it was love at first sight.
A major point of contention in Valentin and Nina’s romance and first marriage was Nina’s jealousy of Anna and Valentin’s past. Valentin was once enamored with Anna when they both worked in the WSB, but she rebuffed him after a one night stand and his love turned to hatred. He later learned it was Anna’s twin Alex he slept with.
Another problem for Nina and Valentin’s relationship was the arrival of Cassandra Pierce. She and Valentin had a past and she attempted to blackmail him into helping her run drugs in Port Charles. She also discovered where he had hidden Claudette Beaulieu, the surrogate who carried his daughter Charlotte. She further blackmailed him using that information.
Valentin’s past secrets continued to cause trouble for him and Nina. Years ago, Valentin learned Anna was pregnant with Faison’s child and gave him up for adoption to protect him. Still angry with Anna/Alex, he was able to locate the boy, Peter, and returned him to his father Faison. This ultimately led to Peter hating his father and the accidental death of Nina’s brother Nathan West decades later. Nina ended her marriage to Valentin over his numerous secrets.
Valentin has often made use of The Nurses Ball to perform songs to try and prove his love to Nina. In 2018 he performed The Book of Love.
In one of his many attempts to woo Nina, Valentin romanced Nina in Morocco where she was on a Crimson photoshoot. When an invaluable diamond necklace went missing, and Valentin mysteriously recovered it, Nina was suspicious.
Obrecht became fixated on torturing Peter for the death of her son Nathan. She was able to pull Nina into her scheme. While hiding Peter in the Cassadine stables a fire broke out trapping Nina and Peter. Valentin ran to their rescue.
In an attempt to win Nina back, he brought Sasha Gilmore to Port Charles to pose as Nina’s long lost daughter, even orchestrating several fake DNA tests. What was supposed to end with Sasha leaving shortly after the truth came out resulted in Sasha becoming entangled in the lie and Nina’s life.
Obrecht discovered that Sasha was not Nina’s daughter and Valentin orchestrated the whole scheme. In return for him convincing Peter to hire her as a medical writer for The Invader, she kept his secret. She also knew the truth would destroy Nina.
In 2019, Valentin performed Nothin Without You. It was another attempt to woo Nina and show her how much he loved her.
At the Metro Court Halloween costume party in 2019, Valentin and Nina attended as Marc Antony and Cleopatra. The couple was making their way back together.
After overhearing the truth about Sasha at Nina’s bachelorette part, a conflicted Lulu finally blurted it out at his second wedding to Nina, bringing it to a halt. Sasha took the entire blame for the scam in an attempt to protect Valentin, but Michael also knew the truth and that Valentin was the mastermind.
Cautious of being hurt by Valentin again, Nina still felt a strong love for her step-daughter Charlotte. Charlotte desperately hoped Nina and her father would be able to re-marry.
The night of Valentin’s third attempt to wed Nina, Ava confronted him on the Cassadine turret. Ava had been working with Nina and Nikolas to stop Valentin. Fed up with Ava, he shoved her off the turret, which was seen by his daughter Charlotte.
Valentin was over the moon when Nina agreed to marry him on New Year’s 2020. However, he had no idea she planned to break his heart at the altar, already knowing that he was the one who orchestrated the Sasha lie. Before she could, Nikolas Cassadine returned from the dead carrying Ava, who Valentin had just shoved off his castle into the waters below, in his arms.
Valentin was stunned to learn he was not the son of Mikkos Cassadine, but the illegitimate child of Helena and an unknown man. She passed Valentin off as Mikkos’ to punish him for his numerous affairs. When the truth came out, he lost the Cassadine fortune and was visited by Helena’s ghost.
Valentin had once gifted Alexis Davis, aka Natasha Cassadine, with her mother’s watch for helping him out with some legal troubles. After Valentin learned he was not a Cassadine, it was Alexis who comforted him and offered advice.
When Nina began to move on with Jasper Jacks, Valentin was unable to accept it. The Cassadine fantasized about shooting Jax dead in his office.
Valentin and Lulu had fought for years over their daughter Charlotte. Eventually, Valentin realized he was not raising her right, and she was learning to scheme and plot just like him. He decided to give Lulu full custody, but Lulu along with Nina made him realize Charlotte needed him. They finally agreed to get along and share custody for their daughter’s sake.
Currently, Valentin has hired Martin Gray to help him purchase up enough shares of ELQ so he holds the majority and thus control of the company. The plan is part of his revenge against Michael Quartermaine, who dared stand up to him in order to protect Sasha Gilmore.
