Why Marienne From You Season 4 Looks So Familiar

Once Gabrielle started booking larger roles in bigger productions, she started to use her real name instead of her stage name. In 2016, she landed a one-off role as a clown named Wackie Jackie in the Disney Channel spy comedy led by Zendaya, "K.C. Undercover." In that same year, Gabrielle followed "K.C. Undercover" with a small role on Nickelodeon's superhero sitcom "The Thundermans," in which she plays Hacksaw, the daughter of thief and owner of Games of Scones coffee shop, Chainsaw.

However, fans would likely recognize Gabrielle from her breakout performance as the recurring character Gaia in the sci-fi CW series "The 100." Her long stint on the show began in Season 4 of the series in the role of Flamekeeper, the guardian of a precious A.I. known as the Flame. As part of a cult known as the Grounders, the Flame held the collective memories of all of their previous leaders. Gabrielle played Gaia from Season 4 through to the series finale in Season 7, in which her character is one of the few who remain alongside series protagonist Clarke Griffin (Eliza Taylor) after the Transcendence.

While playing Gaia, Gabrielle continued keeping busy with a one-off role in an anthology series called "Dimension 404" and a four-episode stint in Season Two of the Hulu survival horror series "Freakish." The show centers on a group of high school students who must band to survive a zombie infestation following a nearby chemical plant explosion. Gabrielle plays Birdie, a teenager who was a part of an experiment before being rescued.
