Grey's Anatomy returns two weeks from this Thursday, on March 15.

In "One Step Too Far," Derek encourages a hesitant Meredith to work with him again in neurology. Picking up where we left off last week (see review and Round Table), Cristina becomes increasingly suspicious of Owen's every move.

Meanwhile, Jackson's mother, Catherine Avery, returns to Seattle Grace with a urology fellow and develops an interest in Richard. Finally, Alex tries to deny the fact that Morgan may be falling for him. Should be very interesting.
