I am so excited to see who gets married in the season opener. My money is on Mark and Lexie...they're the only two people I can picture being in that position right now. Callie and Arizona would be kind of random. Mark and Lexie are more the type who would reconcile and marry right away. I don't know--it just feels right to me. It might be someone we don't expect, though, like Bailey or some minor character like Thatcher. Knowing Shonda, it could be anybody.
I also heard from the Ausellio website that Mandy Moore and the guy who played her husband are definitely returning. The husband is slated to be in episodes 6 and 7 for the season, during November sweeps, and Mandy is going to be back too, but they haven't confirmed whether it will be one episode or two for her. This made me very happy, because I loved Mandy Moore's performance in the finale and was hopeful that she would return for at least one more episode, kind of like that Amanda girl did in the Season 6 opener. There's no news yet on what the storyline will be, but a lot of people are predicting that Mandy's characterMary will die. I guess that's possible, especially considering the fact that the shooting prevented audiences from getting the full idea on how sick Mary really was when Bailey and Percy were treating her. Chances are she was really sick and there just wasn't any time to focus on that in the finale episode...but I am hopeful that doesn't happen. In terms of typical Grey's drama, I'm thinking more along the lines of Mary having PTSD and seeking help from Bailey, with whom she's formed a close bond.
