On the end of GA, George failed, yet he and Callie are trying to get pregnant. Plus, Christina, the strong one of the group, is an emotional wreck because Burke, who isn't coming back btw, left their wedding. Plus, now Meredith's sister is in the mix. And who all thinks that McDreamy is going to hook up with her? So anyway, I'm confused as to how the whole thing is going to work out.
