ABC.com character bio:

Maggie came to Pine Valley because of the death of her twin sister, Frankie. She wanted to uncover how Frankie was really murdered. Frankie and Maggie were not close growing up, which is why no one even knew Frankie had a twin. While Maggie was looking into Frankie's murder, Vanessa drugged her and held her captive, and admitted to killing Frankie. In the end, Maggie was rescued by her cousins, Dr. David Hayward and Leo du Pres, after Vanessa left her to freeze to death.

Maggie immediately grew solid relations with her cousin, David, who did his best to fill the fatherly role in Maggie's life. David's wife, Anna, also grew close to Maggie. While David housed Maggie and sent her to school, he also inspired Maggie to become a doctor just like him. And as David has gone through the loss of his brother and child, Maggie has been there to support him in return.

The other and most important relationship Maggie has built in Pine Valley is with Bianca Montgomery. The roots of their relationship began prior to Maggie's arrival due to the fact that Frankie and Bianca were on their way to becoming a romantic couple. As a result, Bianca was immediately attracted to Maggie, and hoped she would be open to a relationship. For a while, Maggie was unsure about how she felt about most things in life. After finding out her twin sister was gay and that she had a whole new family to get close to, Maggie needed time to process. Maggie needed for Bianca to see her as an individual, not as Frankie. At one point, when Bianca asked Maggie about being in an intimate relationship, Maggie remained ambiguous, and stated she needed to test the waters first because she was still attracted to guys. Maggie's sexuality was the big question on Bianca's mind for months afterwards, but at the very least they were each other's closest friend. Maggie accompanied Bianca to the prom in an effort to show her support. Eventually, Maggie told Bianca that she was not gay, but that she'd always be Bianca's friend.

In college, Maggie met fellow pre-med student Henry Chin in science class. The two were immediately attracted to each other, but Henry was under the impression that Maggie was involved with Bianca. After Maggie explained that she was straight, Henry and Maggie began seeing each other, much to his overbearing mother's chagrin (Henry's mom wanted Henry to be with another Asian girl and to focus on his studies). Maggie and Henry fell in love and lost their virginity to each other. During their relationship, Maggie discovered that Henry had a passion for music, especially the guitar. She encouraged him to pursue his talent; she even made a tape and had it played at an Amateur Night. Unfortunately, Henry's mother disapproved of his dream to be a musician and further pushed him to become a doctor and to avoid Maggie. During a final exam, Henry felt so much pressure, his mind went blank and he cheated off Maggie, with Maggie's consent. The professor accused Maggie of cheating and Henry refused to confess, not wanting to ruin his future career. Maggie, meanwhile, faced expulsion because everyone believed she had copied off of Henry's paper. Maggie broke up with Henry after this betrayal. In an effort to win her back, Henry finally confessed and even consoled her during the death of her baby cousin.

Henry and Maggie decided to try just being friends, and Maggie helped Henry move into Myrtle Fargate's boarding house, after he was kicked out of his own home for being expelled from school. Now free to pursue his music, Henry joined a rock band and left Pine Valley to go on tour. Before he did, he and Maggie shared a heartfelt goodbye.

Maggie was the first person to whom Bianca admitted being raped. Maggie was the first to know about Bianca's pregnancy, as well as being one of the first to know that Bianca planned on keeping the child. When Michael Cambias (who had raped Bianca) avoided punishment, Maggie bought a gun and planned to kill him. As she stood outside Michael's condo, she saw two mysterious figures dragging a large bag from Michael's condo, causing Maggie to flee.

Maggie found herself growing more uncomfortable and jealous of Bianca's relationship with Lena Kundera. As Bianca made plans to leave the country, Maggie impulsively kissed her. Maggie covered and claimed the kiss was friendly, but she remained jealous of Lena and Bianca's closeness. Perhaps in an effort to avoid her feelings she began casually sleeping with Jamie Martin.
