After several rabbis cancel, Charlotte finds a trans rabbi to officiate Rock's "They Mitzvah". At the ceremony, Rock refuses to participate, claiming to not identify with any particular group, religion, gender, non-gender, or anything else. Charlotte, a Jewish convert who never had a Bat Mitzvah, takes Rock's place.
After discussing Rock's gender identity with school personnel, Harry and Charlotte are left confused. Charlotte is dismayed when both Lily and Rock want to update their shared bedroom to reflect each one's individual tastes and ages. Charlotte panics after Lily walks in on her and Harry having oral sex.
