Full disclosure: I hate titles.
Whatever surprise endings are coming forth on a certain episode of a series, like Grey's for example, doesn't have to be wrapped around (in my opinion) in a seemingly intriguing three-word-sentence.
Anyhow, in the world wide web, titles are an absolute big deal. So to keep your mind guessing, (much like everybody else) here's that title of Grey's Anatomy season 10 premiere: "Seal Our Fate".
Theories? Feel free to speculate below!
