While at the Brady Pub, Rafe realized he and Arianna were being watched. However, they were both shocked when they discovered just who was watching them – Gabriela, their younger sister. “Gabi” explained that their mother had sent her to Salem to check in on her siblings who seldom phoned home.

Although Rafe was happy to see Gabi, Arianna was hesitant to let her stay when Gabi announced she’d be visiting for an extended period while on winter break from school. She also mentioned their mother was visiting their grandmother for the holidays and wouldn’t be at home to care for her. Rafe didn’t want her to be alone and, with a little coaxing, Arianna set Gabi up in a vacant room above the Brady Pub.

Gabi made quick friends with the other teens in Salem. She also became smitten with Chad Petersen-Woods. They soon began to date, but Chad abruptly ended things when his ex-girlfriend, Mia, told him that she wanted to get back together. Gabi was upset by the breakup, but remained focus on school, her part-time job at the Brady Pub, and keeping up with her siblings’ hectic lives. Over time, Gabi formed a close friendship with Will Horton and even went to a Salem High formal as his date.

In the fall of 2010, Gabi was devastated when Arianna was killed by a hit-and-run driver. She leaned on Will for support, but was shocked to find out that a distraught Arianna had ran into the street after a fight with him. Will explained his actions and they quickly patched up their friendship. Soon afterwards, they shared their first kiss. As their relationship slowly blossomed, Gabi was there to support Will when his brother, Johnny, was diagnosed with cancer.

Will and Gabi's relationship continued to go well and they decided to take their relationship to the next level after graduation. The two spent the night together. But, soon after Will became distant. Gabi tried many times to get Will to sleep with her again, but she sensed that something was different in their relationship. She finally made the decision to end their relationship in the fall of 2011.

To take her mind off the break-up, Gabi took a job as a receptionist at Quinn's Intensity Day Spa. She also began to have feelings for her ex, Chad; and proceeded to try to break up Chad and Melanie.
