10. Season 7: "Unaccompanied Minor"
In one of the least memorable season finales ever, Meredith (Ellen Pompeo) is granted surprise custody of Zola after making enemies out of just about everybody in the hospital. Everyone tells a white lie, sometimes… and Meredith's was trying to save the life of Richard's (James Pickens Jr.) wife, Adele (Loretta Devine). We still think everyone overreacted about this one.
