News of Meredith’s (Ellen Pompeo) dishonesty in the clinical trial comes to light, leading to unanticipated consequences for both her and others. Did Alex (Justin Chambers) reveal her deception to advance his chances at becoming chief resident, or did he really feel what she did was wrong? What the Chief (James Pickens, Jr.) and Derek (Patrick Dempsey) — and Alex — don’t know is that what Meredith did was to ensure that the chief’s wife (Loretta Devine) would get the Alzheimer’s drug and not the placebo. Will that change their minds?
Then, Cristina (Sandra Oh) finds herself in a compromising situation, which forces her to decide between her career and her relationship. And Owen (Kevin McKidd) posts his decision for chief resident, while Teddy (Kim Raver) makes a surprising choice regarding her love life — and her future.
The season finale of Grey’s Anatomy airs Thursday, May 19 at 9 p.m. on ABC.
