Look what some good writing that doesn't for once focus on stupid relationship troubles or childish bickering can do. This is easily the best medical drama you can ever ask for, and no wonder something like 15 million people tuned in to watch this.
Writing aside, I was wowed by the way the story was told; the back and forth shifts in the scene between interrogation and the actual ER mayhem, the same story told from different points of view. And perhaps looking over the last 2 or 3 episodes, this was actually an amazing storyline to cease the war between Mercy West and Seattle Grace, and to start the bonding process between the docs. Although there isn't a single scene which I cant say I didn't enjoy, the last scene was actually the deal breaker. Cristina made an interesting point, which actually means a lot that what it conveys. While most doctors were blaming April for nearly costing their jobs, Cristina remarks that it could have been any one of them. They've all made mistakes, and unfortunately April's mistake triggered a chain of events that led to the death of the burn victim. The fact that none of their patients died was reason enough for them to keep their jobs, and not because they are better doctors than April.
Seriously, an awesome episode.
