ABC released this scoopy tease for the Feb. 26 episode: "Meredith and George suddenly find themselves at odds at work. Meanwhile Bailey, although technically still on maternity leave, finds herself treating Addison for an unusual feminine issue, and Alex finds himself oddly jealous when Izzie pays more attention to Denny." And although no episode date was listed for this, Meredith learns that the Alzheimer's apple may not fall far from the tree.
