If Grey's Anatomy has any fans left, tonight's two-hour fourth season finale is supposedly the night you've been waiting for!

Just kidding. The show still draws millions of loyal viewers. Yet it's been a long time since something interesting happened on it.

Well, that supposedly changes tonight. Meredith (Ellen Pompeo) and Derek (Patrick Dempsey) are going to be getting together for good.

We know this because the show's own creator and producer, Shonda Rhimes, has already said so publicly. We don't get it either.

Anyway, here's a photo from tonight's show. Meredith is holding what looks like champagne, ready to celebrate ... something.

More than three years later, will a terrific episode finally bring Meredith and Derek together - or will the hit medical drama jump the shark for good?

Also, Alex and Izzie may or may not get together, and there's another love triangle involving possible girl-on-girl action. Gotta love Grey's Anatomy!
