I had to make a post on Sandra Oh, who has made me very speechless from Season Seven of Grey's Anatomy (under a cut)
The OR scene in 7x02 "Shock to the System" I actually had tears in my eyes, then further that Cristina gave the ring back to Owen, I thought to myself that was a quick marriage that ended. But was very please that Owen wouldn't give up (like he did in Season Five) the way he busted into Meredith's house just to get Cristina back. Then Meredith making that grown up speech to him topped it off =)
I'll leave you with my fave scene from the episode =] (under the cut for those to remain spoiler free)
