The Scrubs revival cast is undergoing a major shakeup with Neil Flynn back as a recurring star and Joel Kim Booster leaving. Ava Bunn, who played newcomer Sam Tosh in the first season of the revival, has been promoted from recurring to series regular. She told Deadline: “Both shows have been amazing and working with us to get those performers over to Vancouver [where Scrubs films]. "Now, the respected doctors inspire the next generation while balancing the ups and downs of working in a hospital. "Together with characters new and old, they are navigating this next chapter with laughter, heart and some surprises along the way."
