I thought it was an amazing episode. I first hour or so I was so tense, sitting on the edge of my seat. I work in a hospital and I didn't want to come into work today (completely irrational I know but a couple of my coworkers who watch the show said the same thing)
The only thing that really didn't 'fit' for me was Bailey not looking for other ways to get Charles out. I thought she would have tried a bit harder with that. Overall really well done episode though.
