Maite Perroni, who portrays Becca — as well as her identical siblings Alenia and Tamara — in "Triptych" got her start as an actor in 2004. That year she began appearing as a character named Lupita on a telenovela titled "Rebelde," about six students at a private school who form a band. As is typical for a telenovela, "Rebelde" aired for hundreds of episodes, in over 100 of which Perroni appears. She then went on to appear in at least 100 episodes of six subsequent telenovelas that aired in Mexico between 2007 and 2016.

After this period in which Perroni was a regular telenovela star, she gradually transitioned into becoming a reoccurring actor on Netflix dramas. Perroni notably stars in Mexican thriller series "Dark Desire," which premiered to Netflix in 2020 and concluded upon the final episode of its second season in 2022. In "Dark Desire," Perroni portrays Alma Quintana Solares, a professor who has an extramarital affair that incites much of the intrigue that follows throughout the series. Perroni also appears in a single episode of "Who Killed Sara?," another Netflix thriller.

Given her large body of work and recent prominence on Netflix series, then, it's entirely possible that in the wake of her work as Becca on "Triptych," Perroni will persist as a mainstay of the streaming service moving forward.
