Scott Foley Reprises Sean Kelly in Scrubs Season 2 After 2 TV Setbacks

Q: As classic stars return to Sacred Heart, what secret reason caused two major Season 1 revival actors to quietly exit?

There does not appear to be any publicly confirmed “secret reason.” The two notable Season 1 revival actors who quietly exited are Joel Kim Booster, who played Dr. Kevin Park, and X Mayo, who played Charge Nurse Raymond, and the reporting only says they are not returning for Season 2. The available coverage frames their departures as part of a broader Season 2 cast reshuffle rather than a disclosed behind-the-scenes controversy. ABC and the producers have emphasized other changes instead: Ava Bunn was promoted to series regular, Rachel Bilson’s role was expanded, and more original-series players such as Scott Foley and Neil Flynn were brought back into the mix. Trade reporting also suggests the show is rebalancing its ensemble around the core trio of J.D., Turk and Elliot, while keeping some newcomers and reducing others. In that context, Park and Raymond were dropped without an official on-record explanation. Booster publicly responded graciously on Instagram, writing that he was “so honored” to have been part of the show, which further suggests an ordinary creative or production decision rather than a known scandal. So the factual answer is that no hidden cause has been substantiated. The exits were quiet, but the public record points only to a creative cast adjustment for Season 2.

D23 footage on Aug. 15 showed Scott Foley, 54, returning to Hulu’s Scrubs revival in season 2 as Sean Kelly, his recurring role from seasons 1, 3 and 8 of the original series.
Foley had missed season 1 despite being invited back; he said Zach Braff asked him to return, but an earlier production call could not be matched with his schedule.
The new role follows two recent setbacks: Foley’s character Seth died in a May episode of Will Trent, and Prime Video canceled It’s Not Like That in July after one season.
Foley’s Scrubs return extends a long working relationship with creator Bill Lawrence, with the actor citing past collaborations including Cougar Town, Undatable and Whiskey Cavalier.
