Stephanie reveals her past and the sisters prepare for a dinner party at their house on tonight's episode of Grey's Anatomy, airing at 8 p.m. ET/PT on ABC.

In "Old Time Rock'n Roll," Owen suggests the interns learn a vital lesson on how to break bad news to patients' families, and Arizona's 90-year-old patient reassures her that she's destined to find love again. Meanwhile, the sisters completely forget about the dinner party they're hosting for everyone.

In the sneak peek video below, Maggie wakes up immediately regretting her one-night stand with the intern. She tells DeLuca to get out of the house without anyone seeing him, but of course he runs into Amelia in the hallway. Maggie's hot hookup isn't going to remain secret for long.
