Plane crash / Lexie dies

Tragedy struck when many members of the staff were involved in a horrific plane crash. Some fared well in the crash, other didn't. Other than what we assume is a dislocated shoulder, Cristina seems to have made it through okay. Arizona's leg is in pretty bad shape and at one point she went into shock. Meredith seems to be okay, but has a nasty cut but on her leg and the back of the head. Derek was far off in the woods with his hand trapped in-between some mangled pieces of metal. He did what he had to do; he smashed his own hand in order to free it. He made his way to the others where Meredith and Cristina have to do some crude impromptu surgery to try and save his hand. Mark seems fine at first, but it became very apparent he wasn't. Mark's chest was filling with blood. To save his life, Cristina and Meredith took a plastic tube and performed a procedure to drain away the blood. Mark is alive for now, but may not last long if help doesn't arrive soon. Poor Lexie didn't make it. She was found trapped under a large piece of the plane after the crash. There was nothing anyone could do. Her last moments were of her and Mark holding hands; expressing their love for each other.
