Charlotte Ritchie is joining the season four cast of "You" as Kate, who, according to Deadline, is a gallery director and the daughter of a bohemian single mother who's "smart, independent, suspicious, [and] misses nothing." In other words, she'll probably be giving Joe a lot of trouble come season four.
You know Charlotte from the British series "Ghosts" and Netflix's "Feel Good", and she recently wrapped production on "Wonka" with Timothée Chalamet.
