Grey's Anatomy is all new again this week with "Moment of Truth."

Looking ahead to the following week and the start of May sweeps, as season eight winds toward a dramatic conclusion, ABC has released photos from the May 3 episode, "Let the Bad Times Roll."

In this installment, the residents agonize over their oral boards, reliving every answer they gave during their exams, while Arizona's close childhood friend comes to Seattle Grace in search of medical help.

At the same time, the doctors work on a patient who is missing one third of his skull; and Julia asks Mark to start a family with her. Meanwhile Catherine tells Richard that one of his residents has failed.
