An Awkward First Meeting
Sami first met Lucas when she went backstage at a concert...and found him making out with the star she was there to see! Luckily for her, she got a second chance when Lucas' mother, Kate, gave her an internship. Sami thought Lucas looked familiar, but he had no memory of meeting her and was too busy trying to keep up his phony good-boy image with his mom to worry about it.
Partners in Crime
Sami soon discovered that Lucas shared her love of scheming her way to whatever she wanted. And what Sami wanted was older sister Carrie's boyfriend, Austin! Lucas was interested in Carrie, so he and Sami worked together to break up Carrie and Austin, unaware that they weren't just two friends doing each other an illicit favor.
Lucas Comforts Sami After She is Raped
Sami eventually moved on past both Lucas and Austin, setting her sights on Lucas' friend Alan, who happened to be obsessed with Carrie.

Lucas comforted her and later both confronted Alan and helped Sami get proof so that Alan could be convicted at trial.

Lucas continued to be protective of Sami after he learned about the rape, and when he heard some girls bullying her about it, he stepped in. One thing led to another and that night, Sami and Lucas made love for the very first time.
Who's Will's Father?
Soon after making love with Lucas, Sami discovered she was pregnant. She thought the baby was Austin's, but later found out it was not. Determined to hold onto Austin, Sami lied about the baby's paternity, but Lucas began to develop fatherly feelings for his "nephew" and Carrie spilled the beans at Sami and Austin's wedding. This led to a long period of strife between Sami and Lucas.

The Franco Affair
Sami was so determined to keep Lucas away from Will that his love for her vanished and was replaced with hate. Sami nearly lost her freedom -- and her life -- when Lucas caught her new boyfriend Franco attacking Kate and killed him, which Kate then framed Sami for. Meanwhile, Lucas fell for Nicole, and Kate paid her $5 million to break up with Eric and marry Lucas so that Lucas could get custody of Will now that Sami was out of the way. However, Lucas couldn't do that to Sami and rushed to try to stop her from being executed after she was convicted of murder and sentenced to death.

The First Reconciliation

Lucas believed her, but with Nicole's help, Sami proved her innocence and the wedding was back on.
The Stan Disaster
While Lucas and Sami were broken up, Sami's mental health deteriorated to the point that she began dressing as a man and called herself Stan. Stan was a troublemaker who sold painkillers to an addicted John Black and wreaked havoc in Salem. Unfortunately for Sami, when she and Lucas reconciled, Kate interrupted their wedding to reveal that Sami was Stan, causing the couple to break up once again.
The Third Break-Up
Sami and Lucas tried a third time to get back together after Will ran away because he was upset about his parents' aborted marriage. This time, however, Lucas learned that Sami had blackmailed Lexie into telling Carrie that Carrie couldn't have children and he again walked out on Sami.
EJ Rapes Sami
Some time later, Lucas and Sami managed to mend fences. By this time, Sami had kissed the evil EJ Dimera, unaware of his true identity, and then rejected him when she learned that he was Stefano's son -- and Kate's lover. Unfortunately, Lucas and Sami got trapped in their car during a snowstorm, and EJ came to the rescue. His help came with a price, however: Sami had to sleep with him or he would let Lucas die.

Soon after the rape, Sami discovered she was pregnant again, this time with twins. She hoped against hope that the twins were Lucas', but it turned out that her son Johnny was EJ's. However, her daughter Allie was Lucas', which meant that she was now bonded to Lucas through two children. Lucas, for his part, cared about Sami's welfare so much that he did his best to stall EJ while Sami was giving birth and even handcuffed EJ in the Pub to ensure he left Sami alone.

Without Lucas there, Sami had to move on, at least for the moment.
