The CW has announced that Justina Adorno is joining the cast of the extraterrestrial drama in a recurring role when the show returns for its second season in early 2020. Making her first appearance in episode 2 of season 2, Adorno plays Steph who, according to the network, is a “witty, sharp-tongued, well-educated young woman, who isn’t afraid to express her opinions — even though they tend toward controversial in some circles. Steph never apologizes for being her entire self.” Sounds like she’ll fit in nicely.
