You were married to Arizona. You are a cardio surgeon, and you worked in the same hospital as her before. It was years ago, and you two got divorced over stupid reasons and arguments.

Since then, she has worked at Seattle Grace, and has somewhat forgotten the whole story. Here, everyone knows about the fact that she had a wife before coming here, but she never talked about it. And you have no idea that she works in this hospital...otherwise, maybe you wouldn't have just been hired there, years after your divorce.

She's with Bailey and Alex, just coming out of surgery this morning when she sees Cristina laughing with someone from behind. Without doubt the new cardio surgeon that everyone has been talking about for a while. The person is facing away, and has the silhouette of a woman.

"Oh ! Let's greet the newbie ! I hope she's hot !"

Alex grins, hurrying towards Cristina. They follow, curious to see who could make Yang laugh in the first day of work.
