A scene from the February 17, 2011 episode of Grey's Anatomy shows Mer and Cristina sharing a moment. These two will always be best of friends even if friendships ebb and flow.

We love 'em all. Each and every one. Here's a shot from "P.Y.T. (Pretty Young Thing)".

Owen and Cristina share a moment. Any moment featuring these two is prety much guaranteed to be awesome.

We can't get enough of these three.
