What Happened to Rex on Days of Our Lives

Longtime fans remember Rex Brady on Days of Our Lives as an alien, but now he’s just Roman’s son. And if that’s not weird enough, the character returned to the soap, but played by the actor who used to play Brady! Don’t worry, we’ll help it all make sense for you… Rex was originally played by actor Eric Winter from July 2002 until his departure in July 2005. The character returned to DAYS in October of 2018, recast with Kyle Lowder, who viewers will remember as Brady Black from 2000-05. (The role of Brady has been played by Eric Martsolf since 2008.) It was just a short stint, with Rex leaving town again in August of 2019, but the character has continued to resurface for visits to Salem in the years that have followed. After a stint in 2023, Lowder reprised the role again in April 2025.

The character of Rex was introduced alongside his twin sister, Cassie, back in July of 2002, when there was a meteor shower and they were discovered wearing foil outfits on the side of the road by Belle Black and Shawn-Douglas. Nicknamed the “Gemini Twins,” the pair were originally believed to be aliens as they also spoke no English. However, they quickly learned, and Rex wound up having quite a superior intellect.

After a while, genetic testing revealed that they were the twin offspring of Tony DiMera and Marlena Evans, conceived through scientific means. Rex struck up a relationship with Mimi Lockhart, and she was there to support him when he learned the real truth about his parentage. It turns out that Rex and Cassie were actually created from the sperm of Roman Brady and an egg from Kate Roberts! 

The revelation changed Rex’s attitude, and he became moody and violent, worrying his friends. And when people started dying around Salem, he became the prime suspect. Tragically, he was then devastated when his twin, Cassie, became one of the Salem Stalker’s victims. Thankfully, all the murdered Salem residents turned out to be alive on an island, and it was all just an elaborate charade.

Rex broke up with Mimi when he discovered that she had aborted his baby without telling him, and then left town with his sister. The twins were mentioned briefly in late 2017 as part of Dr. Rolf’s mad experiments, but in 2018, Rex returned home to Salem once more, revealing his engagement to Sarah Horton. But that engagement was broken off when Sarah found out that Rex had cheated on her with Mimi, and the baby Bonnie was passing off as her own was actually Rex and Mimi’s! When Mimi and her daughter left town, Rex went with them, but he soon returned, begging Sarah for another chance. She had become smitten with Eric, but when he lied that he wasn’t that into her, Sarah forgave Rex and they became man and wife.

However, she was still very much drawn to Eric and ultimately gave in to her feelings for him, so a heartbroken Rex quit his job at the hospital and left Salem in 2019 to move to Chicago and start over. But less than a year later, Sarah didn’t realize she would later run into her ex in Paris, of all places! Realizing she’d abducted Kristen DiMera‘s daughter, whom she’d believed to be her own for a year, Rex tried to convince her to do the right thing. But Sarah tied him up and refused to listen, abandoning him to be rescued after she’d tried to leave the country!

In 2021, Sarah was about to marry Xander Kiriakis, and Rex was startled when she threw herself at him, not realizing it was actually Kristen in disguise! He was caught with “Sarah” by Xander, who blew up and attacked Rex. “Sarah” claimed she still loved Rex, but he was later heartbroken when she dumped him, too, and left Salem again.

Rex came home in December 2021, pleasantly surprised to find Kate and Roman reunited and enjoying a romantic dinner together. However, everyone seemed confused when he explained he had no idea where Sarah was! As he returned to Chicago after the new year, Rex still had no idea that Sarah had been kidnapped by Kristen. He also missed out on her return and believing she was Renee Dumonde for a time. Though Rex did step in to confirm Sarah’s alibi when she was suspected of murdering Abigail.

When Kate, Marlena, and Kayla all fell deathly ill in September, Rex returned to Salem in the hopes of helping save their lives. He suspected their illness was the same that Roman had suffered previously and asked Dr. Rolf for help in developing a cure, but he was unable to assist. Rex next visited at Christmas to follow up with Kate and make sure that she was definitely cured. Tragically, the three women relapsed, and Rex sadly declared Kate dead. After having rebound sex with Rex, Sarah confessed she was having Xander’s baby, and he offered her a job at his hospital in Chicago, which she quickly took.

Unfortunately, in May 2023, when Bonnie went to the Windy City for a visit, she saw Sarah’s baby bump and didn’t believe Rex’s claims that the child was his! Later, Sarah rebuffed Rex’s affection, admitting she still wasn’t over Xander, no matter how much she wished she was. As Sarah worried about the secret coming out, Rex offered to marry her so that he would legally be the baby’s father. When Philip returned and confessed he was still in love with Chloe, Re begged his brother not to go after her for fear that a single Xander would be more dangerous. But after Victor’s funeral, Sarah went into labor and gave birth, passing out before she could confess to Xander it was his daughter. Unfortunately, Rex was the one who blew the secret when Chloe overheard him confess the truth to Philip, and she quickly told Xander, who crashed the wedding, though not before Rex and Sarah exchanged vows. Rex was insistent that Xander would never be Victoria’s father, but when Sarah admitted she wanted a divorce, Rex realized he could never compete and went back to Chicago.
