After a little tease about where we're going to end up at the end of this week's episode, we pick up where we left off last week with everyone pretty much on the edge of death. Lexie is covered in Seth Green's blood, Derek is elbow deep in Mary's brain without a navigational system, The NAZI's blood pressure is bottoming out, and Ray is still upside down in an ambulance. This is where we find out who will live and who will die.
