Always throwing in confusion. It was expected. It was not unexpected at all for the viewers to know that chaos would rule a story lines.
-- Alex -- Yet another finale in which Alex is thrown under the boat. He finally gets someone but within 2 episodes that relationship abruptly cuts off to which Alex does something rash. Textbook from season 1. This development was made for 2 reasons.
1) set up for some Meredith implosion (described below)
2) to get rid of the ob attending, who was unconvincing as a doctor at every level. Better suited for a cheesy role. I saw that after couple episodes and so did the show's casting crew.
-- Meredith -- Her life was already complicated and merely settling down. Once again her life gets screwed and everything goes back to square 1. Boring. The extra work and family fiasco was excessive. Teddy falls for the to-be-dead-soon guy? I can't even remember that guys name. The character they attempt to creat never existed. A borderline attempt at creating someone and an even further attempt at manufacturing a last minute relationship from thoughts of pity for no reason at all. She was set for Germany and pulled a 180.
-- No wedding -- Instead another mass casualty. There was absolutely no point to yet another mass fatality situation. This was introduced because the whole Torres situation resolved in a disappointing, sped up wedding in which everything she used to stand for was thrown aside for a backyard celebration. The religion issue played out. Understandable, but the crash and wedding flew by. Remember when Izzie had half a season for a wedding dress? Thought so. They could have done a lot more this season and brought in the parents as well.
-- Yang -- Though its true Christina never wanted a kid, the way it was presented was good. The development covered for the resolved Owen PTSD season. Good start to her story.
-- Chief Resident -- The only piece that made sense in the episode was April become C.R. she's always been the levelheaded resident and the only one who delegated and does any job beyond the incessant desire to cut.
