Mandy Moore is scrubbing up for another medical show, the season finale of "Grey's Anatomy,"
Details of the May 20 episode are being kept top secret, but it will be two hours, and TVguide.com reports that Mandy will play a patient named Mary treated by Chandra Wilson.
It's a nice return for Moore who has been quiet of late. And a familiar medical setting. In 2006, Moore guest-starred on two episodes of "Scrubs" which coincided with her dating of "Scrubs" star Zac Braff.
