Meredith: "What's wrong?"
Derek: "There is no food. I'm hungry."
Meredith: "I just ordered pizza."
Derek: "For breakfast?"
Meredith: "We've been up for 39 straight hours. It's dinner, it's a very very late dinner... Oh, that cheese is old."
Derek: "I'm hungry, I might die."
Meredith: "Don't eat the old cheese. Come and sit down by me and put your head down."
Derek: "I could put a little salt on your nose and take a bite."
Meredith: "Pizza will be here any minute."
Derek: "We'll be okay. Just the two of us, if that's what you want."
Meredith: "I love you."
(the doorbell rings)
Meredith: "Pizza!" (goes to answer to door)
Derek: "Don't start eating that pizza without me... Meredith?"
Meredith: "Derek?"
Derek: "Yes?"
Meredith: "Isn't that our baby?"
Derek: "Yes. Yes it is!"
Janet: "She's yours."

Victims of a sudden impact are some of the hardest to treat. It's not just the collision that injures them. It's everything after. The centrifugal force keeps them moving, tossing them from vehicles, throwing them through windshields, slamming their internal organs into the skeleton. Their bodies are injured over and over again. So there's no way to know how much damage has actually been done. Until they stop.

You can't prepare for a sudden impact. You can't brace yourself. It just hits you. Out of nowhere. And suddenly, the life you knew before is over. Forever.
