 Cox and Kelso still have some issues since Cox punched him a week earlier, and Kelso is still squeaking. Although JD is now starting with the third year; he still needs Dr. Cox s help identifying a patients problem, so the four of them do every single test trying to figure it out. Elliot has some issues with her self confidence, so she buys a car, she meets Sean again, and she goes into a transformation moment that changes both her looks and behavior, so she provides some big help to JD in his patient s problem.
