The Bailey story made up the majority of the drama of this episode. Jackson decided to call in the CDC after her second patient died. Although many of the board members were actually on her side, Bailey felt isolated and attacked, especially after she overheard Richard claiming it was all her fault.

This plot worked for us. We especially liked Bailey's interview with the CDC agent. The way the show interwove flashbacks in the early part, and Richard's present-day surgery later on, was inspired, and Bailey's distress when she thought the infections really were her fault was heartbreaking — as was her intense fight with Richard at the end.

Meanwhile, Jo decided to move in with her boyfriend, much to Alex's distress. But his attempt to make nice with said boyfriend accidentally backfired when he revealed Jo's hard-knock backstory, which she had kept a secret. Now she's furious at him ... and he realizes he's in love with her. Whoops.

In Owen news, Ethan's mother collapsed and died, and his grandmother proved to be emotionally fragile. When Cristina saw how much Ethan meant to Owen, she realized she's losing him. Sad, but we're glad their difference over children will finally get addressed.

Other things that happened: Meredith pestered Cristina to promise to be in the room when she gives birth (funny), April and Matthew reunited — but not before Jackson emphasized he'll never regret sleeping with her, and a family reunion gone wrong provided a fairly lighthearted side case that had bigger implications when a wannabe journalist got too inquisitive about Bailey.

Overall, it was a solid start to the end-of-the-season push. We give it 4 stars. What about you?
