On the April 26 episode of Grey’s Anatomy, it's the "Moment of Truth" for the residents.

Meredith, Cristina, Alex and their cohorts travel to San Francisco for the oral boards, a critical moment in their careers that may also dictate whether one or more cast members return for a ninth season.

Accepting a job at another hospital makes for a convenient "out," after all. While it's unclear if anyone will leave Seattle, expect the old Cristina to return and Mer to battle a health issue during the boards.

Meanwhile, sparks fly when Richard and Catherine (Debbie Allen) bump into each other at a hotel, and Alex feels guilty about being away from the hospital when Tommy's health takes a turn for the worse.
