When the Chief starts spending night after night at the hospital, Adele assumes the worst. We laugh at Miranda's reaction when Adele asks her, "Are you having an affair with my husband? You're more married to that man than I am." Callie helpfully explains that Richard is Miranda's "work husband" and that she's his "work wife." Adele accepts Miranda's promise that she is not the one sleeping with her husband, but now Miranda is on a mission to find out who the other woman really is. We're in disbelief when she confronts the Chief and tells him she knows it's Izzie! "It's why you ignored the DNR, it's why you fired her, it's why you two were screaming at each other in here," she says. Richard explains that he's not having an affair, he's simply got too much on his plate. In fact, he's handing over all his surgeries to her, effective immediately! This is after he's committed a serious error during surgery—one his "work wife" fixed and kept a secret.
We're assuming that Richard's just married to his job, but we're shocked when we learn the truth: He's been drinking! It explains everything: His mismanagement since the merger, the car accident, and the surgical error. We wonder what Meredith (who's back at work) will say to Derek about her suspicions.
