John Reese:
I was supposed to save you, but I was too late. You've ingested polonium, Doctor. You're dying.

Dr. Richard Nelson:
This is insane. How do - who are you?

John Reese:
Nosebleeds, jaundice, hair falling out. It's radiation poisoning.

Dr. Richard Nelson:
I'm aware how radiation affects the body, but how do you know all this?

John Reese:
You were poisoned a few hours ago, which means, in less than 24 hours, you will be dead. I'm sorry, Doctor.

Dr. Richard Nelson:
I-I don't understand. How - Who would want me dead?

John Reese:
You would know better than I. Look, you can stay there and die in that bed, or you can get up and help me find the bastard who murdered you.
