Carnegie Mellon's drama faculty told her to consider directing instead. She graduated in 2017 anyway, moved to New York with no connections, and was about to take a day job when the Hill House casting call arrived. As Nell Crain in Mike Flanagan's 2018 horror series, she built a full arc out of a ghost who doesn't speak for most of the show, including a climactic solo monologue that critics couldn't stop writing about. Flanagan cast her as the lead in Bly Manor. Netflix then put her in You as Love Quinn, a character who spent one season hiding that she was a killer.
The Netflix horror wave that made her famous has crested, and she's not trying to recreate it. Her 2024 Broadway debut in Sam Gold's production of An Enemy of the People was a deliberate pivot toward legitimacy. Disinherited, an FX pilot from Better Call Saul creator Peter Gould, has her and Kiera Allen playing sisters thrown into a world of generational wealth and buried crimes. Forbidden Fruits, a comedy horror ensemble film, opened in theaters in March 2026. She's building toward something more durable than a streaming brand.
After CMU told her to consider directing, she spent six years building a career on Netflix instead. Then in 2025 she directed her first short film, Get Lost. Make of that what you will. She also originally read for Beck in You, not Love Quinn. The showrunners moved her to Love Quinn after noticing her chemistry with Penn Badgley, and that accident of casting gave her a character with a murder arc instead of a victim role.
