During a recent visit to the TVGuide.com studios, we put the actress to the test. We named off her castmates well-known roles (and a few less recognizable characters) that her costars played before joining the CW spy drama. Did Q know that Devon Sawa starred in Casper as a kid? Or that girls swooned for Shane West in A Walk to Remember? And who once played a girl named Jenny in Hot Tub Time Machine?
