It's Richard's first day back and he asks Derek for a "low-stress day." That all changes when doctor Harper Avery, who hands out prestigious awards in his name every year, arrives at the hospital with abdominal complications. He requests that Richard do the surgery. Although Derek thinks it's a bad idea, he agrees.
Cristina is abuzz to hear that THE Harper Avery is in the hospital and is desperate to impress him, which is why she bends the rules to perform an "ex vivo" lung surgery without Teddy's consent.

Richard confesses to Derek that he wants a drink and asks to hand over the surgery to Miranda. Derek surprises us by disagreeing: "Two months ago, you never would have told me you want a drink. You would have had one." He tells Richard to do the surgery, with Miranda assisting.
During the surgery, they discover the reason for the complication: Harper's own choice of sutures, which he's allergic to! Jackson is amused that Harper's condition is his own fault. Meredith tells him she knows what he's going through, but that if it were her mother, she'd go see her. "And I definitely would want to learn from her." Jackson not only goes to visit Harper, he introduces several of the staff to his grandfather.
