"Chicago Fire" may be the first time Mayo has portrayed a firefighter. However, this isn't the first time she's ever worked on anything created by Dick Wolf. In 2011, Mayo landed her first TV role in "Law & Order: LA," a spin-off series that traded in east coast crime for the west coast. Mayo played a character named Anna in the episode "El Sereno." The episode centered on a mass murder at a primarily Hispanic office. "Law & Order: LA" didn't have a long span on television as it was canceled after one season. Still, as the first role for Mayo, the actor remembers being grateful for the opportunity.
As she said in an interview for Fangirlish, "I remember feeling so excited that I had booked a job. It had been over a year of me auditioning for TV and film and not booking anything, so when I finally did, it felt so surreal and very exciting."
Mayo's current role as Stella on "Chicago Fire" truly brings her career full circle, but if she had her way, she'd love to revisit "Law & Order." She noted in an exclusive Looper interview that as far as dream crossovers for her character, she certainly wouldn't mind if Stella went to work with Olivia Benson (Mariska Hargitay) of "Law & Order: SVU." Our fingers are crossed for that "Chicago Fire" and "SVU" crossover special.
