Geoff: After you start to feel thirsty, you find yourself feeling impatient, maybe even a little sick. And your pulse starts to go up, then there's the headaches, dizziness... when it gets bad, your vision will blur and you'll find it hard to walk and talk. Your tongue swells up, your skin shrivels, you twitch, you go deaf and then you die.
Elizabeth Dunn: Have you ever loved anyone so much you didn't care what happened to yourself? You just had to be with them. If they look at you, your heart stops. If you feel their breath on your skin, you just ache. Have you ever craved anyone so much you didn't exist any more?
Dr. Philippa Horwood: No.
Elizabeth Dunn: I have.
