Here is a teaser from E!'s Spoiler Chat:
Lee in Atlanta: Will Cristina and Owen on Grey's have a new addition to their family this season?
We just asked Kevin McKidd if there might be a season-ending Cristina-Owen baby surprise, and he told us, "That's an interesting idea; I never thought of that. It's interesting because there have been having a lot of discussions about that, heated discussions about that. So it's possible. But I'm not saying it's definite."
