Michael Mosley and Kerry Bishe have landed two starring roles on Scrubs.

Mosley, who guest-starred on The Mentalist last season, will portray Drew, a scruffy and attractive older medical student that is getting his second shot at school after a significant meltdown a decade earlier.

Bishe, meanwhile, will play Lucy, the show's new narrator, according to creator Bill Lawrence. She was most recently seen on Royal Pains.

The character is a 22-year-old first-year medical student. She's beautiful and the first in her family of commercial fishermen to go to college.

Last week, Dave Franco was also cast on the new season. He'll take on the role of Cole.
