The second season of ABC’s *Scrubs* revival will feature several cast changes. Joel Kim Booster and X Mayo are leaving their recurring roles, while John Higgins and Keyla Monterroso Mejia join the cast; the changes are intended to create new comic and dramatic dynamics around J.D.

Booster’s Dr Kevin Park is being replaced by Higgins’s Chief Resident Grant, who will serve as a new rival positioned beneath J.D., echoing J.D.’s original relationship with Dr Cox. Mayo’s departure as nurse Raymond is due to scheduling commitments rather than the storyline, while Ava Bunn has been promoted to series regular as intern Sam Tosh, whose role will explore how people increasingly seek medical information through social media and ChatGPT.
