Cole Aaronson

Cole Aaronson is one of the fresh-faced med students thrown into the teaching hospital's halls during Scrubs' final stretch, still finding his footing under the watchful, weary eyes of the veteran doctors. He's eager, a little green, and trying to prove he belongs among people who've already seen it all.

Dave Franco brings an easy, understated charm to a role that could have been forgettable filler among the show's late-run cast shuffle. He plays the newcomer's nerves and ambition with a light touch, letting small reactions do the work rather than pushing for big laughs, which fits neatly into Scrubs' loose, hangout rhythm.
