Scrubs season 2 starts, Ava Bunn promoted, two exits

Production has officially begun on the second season of the revived "Scrubs" series, bringing a series of cast changes as the show prepares for its return this fall. The core trio of Zach Braff, Donald Faison, and Sarah Chalke will reprise their roles as Dr. John "J.D." Dorian, Dr. Christopher Turk, and Dr. Elliot Reid, leading the new installment.

A significant promotion sees Ava Bunn elevated to series regular status for the upcoming season. Bunn plays Dr. Sam Tosh, a medical intern who uses social media to solve problems and works alongside J.D. The season will also feature the return of several original cast members in recurring capacities, including John C. McGinley as Dr. Perry Cox, Judy Reyes as Carla Espinosa, Neil Flynn as The Janitor, and Robert Maschio as The Todd. Christa Miller will guest star again as Jordan Sullivan.

The new cohort of medical interns, introduced in the first revival season, will also return. These recurring characters are played by Jacob Dudman (Asher Green), David Gridley (Blake Lewis), Layla Mohammadi (Amara Hadi), and Amanda Morrow (Dashana Trainor). Other recurring players include Vanessa Bayer as Sibby and Michael James Scott as Dubois.
