Richard has completed rehab but he won't get his job back until the board approves. In the meantime, Derek offers him a spot as a "general attending surgeon," and he refuses. But he does take Derek up on his offer to be part of the lecture series.
Miranda starts off the series with a case from 2003. We flashback to when she was an intern with long braided hair and called herself "Mandy!" Her resident couldn't stand her, since Miranda was clearly better at diagnosing. Richard notices the animosity and tells her, "Surgery is a shark tank. Make sure you're a shark too, not a minnow."
