My first thought in this episode was the realization of just how stinkin' many characters and storylines are going on at once. The break was so long I forgot about so much. Legitimately forgot all about Owen and Amelia splitting up until just now.
I was one who wasn't sure about Jo's DV storyline. I am torn 50/50 on it. On one hand, Matthew Morrison is perfect in his role. I mean he was so good at it. Camilla was pretty good too, which is a shock to me. The actual story, though, was a bit meh. Meredith in the OR stole the show for me. She had no time for Paul's crap, and I loved that. I expected a confrontation between Paul and Jo, but the locker room scene fell flat. That this man, who was a complete charmer and snake in disguise, would come back just to confront her in front of his current fiancé and Meredith wasn't believable to me. Also, add me to the people who are a little confused about Meredith being the one to help Jo this way when she has never even pretended to like her. This episode just made it a little more clear to me that Jo is a character pretty much there for Alex. She had a standalone story line and they had to pull people out of the woodwork to help her out with it because the writers never bothered to give her any relationships with anyone but Stephanie and Alex. I also realize that Meredith being there for Jo is more for Alex than it is for Jo.
Maggie and Jackson is still not good. I am not warming up to it. I've never liked Maggie and, as time goes on, I like Jackson less and less. They just don't have very much chemistry.
