Lucas Horton is a fictional character on the American daytime soap opera Days of Our Lives, portrayed by Bryan Dattilo.

In late 1992, Days of our Lives began to introduce a new teen scene to appeal to younger viewers featuring long-time characters Sami and Carrie Brady, and the arrivals of Austin Reed and Jonah Carver.

In early 1993, the show decided to expand by introducing Jamie Caldwell, Wendy Reardon, and Lucas Roberts.

[7][8] Executive producer Ken Corday spoke out on the firing, stating that it was simply to give the character of Lucas a "rest".

[11] Executive producer Corday later confirmed that Dattilo's stay on the soap could be extended for an unknown amount of time.

And then when I got home and read the episode, where I really didn't say much and nothing happened, I thought, 'If that's going to be my last episode, I don't want to go out like that.In May 2011, the soap announced its choice to reinvent the series and fire its current head writer Dena Higley for former Passions head writers Marlene McPherson and Darrell Ray Thomas, Jr.[18][19] Speculation lead to rumors of Dattilo possibly returning to the series.

I am trying to take the job more seriously and make it about the work and not be the "comic relief" so much because people then tend to have you fall into that role everyday.

It's great to be back and to figure out where I fit in the best and where I can plug myself in the best.In June 2018, it was reported that Dattilo will be exiting the role of Lucas; making his last appearance on November 15, 2018.

He quickly befriends Sami Brady (Alison Sweeney) and the two start scheming to break up her sister, Carrie Brady (Christie Clark) and her boyfriend Austin Reed (Patrick Muldoon), because Sami wants to be with Austin and Lucas wants to be with Carrie.

Lucas is shocked to learn that he is the illegitimate son of Dr. Bill Horton (Edward Mallory) and that Austin and his sister Billie Reed (Lisa Rinna) are his maternal half-siblings.

After Lucas' mother Kate is apparently killed in a plane crash, he learns that Vivian is involved and blackmails her into finding Sami and bringing her home in time to stop Austin and Carrie's wedding.

After being injured in a fire purposely lit by his mother in the Kiriakis Mansion, Lucas is sent away to a rehab center due to his alcohol addiction.

Kate has Sami and Brandon drugged and put into bed with each other, where Lucas finds them together on the morning of the wedding, and he is devastated.

Lucas joins the team to rescue his half-brother Philip Kiriakis, unaware that Sami (disguised as Stan) has infiltrated the group with a plan of her own.

Back in Salem with Philip's rescue successfully accomplished, Lucas and Sami again grow close and get engaged.

Later, Lucas accepts a job with his former stepfather, Victor Kiriakis, and travels to California to investigate a possible takeover of High Style.

Sami begins a short relationship with her neighbor EJ Wells, who she later discovers to be a son of Stefano DiMera.

She is disgusted, immediately referring to his proposal as rape, but unwillingly submits to save Lucas' life.

This time the test reveals that the girl, Allie, is the daughter of Lucas, and the boy, Johnny, is EJ's son.

Lucas tells Kate that he hired a nurse to watch Johnny and Allie and went to the church and shot EJ.

Lucas returns to Salem in early 2012 at Sami's request and announces that he is engaged to a woman named Autumn.

Though Lucas initially believes he can deal with it, he has trouble adjusting and discourages Will from dating Sonny Kiriakis (Freddie Smith).

Lucas is furious when Sami tries to help EJ prove his innocence in Stefano's apparent murder and breaks up with her.

Lucas also supports his sister, Jennifer Horton (Melissa Reeves) after the death of her husband, Jack Deveraux (Matthew Ashford) but doesn't approve when she reunites with Daniel.

Lucas, Justin, Kate and Sonny rush her to the hospital, and the wedding is ultimately put off due to her diagnosis.

Lucas nose-dives into alcoholism, and he ignores the appeals of his mom Kate, sister Jennifer, and his Aunt Maggie to get help and enter rehabilitation.

Eventually Sonny and Sami find Will, and despite having lost all memory of his life before being strangled, Will decides to return with them to Salem, where he and Lucas are finally reunited.

However, Will's return is no magic bullet for curing Lucas' alcoholism, and he crashes his car whilst driving under the influence and ends up in hospital.

Lucas rekindles his romance with his ex-wife Chloe, including inviting her to a date at the ice rink.

While in jail, he deals with Orpheus' schemes and later aids in Harris Michaels' effort to stop Clyde Weston's drug ring.
