Marcus: I got the letter. Thanks.
Fiona: Oh, my God. I'd forgotten.
Marcus: You forgot? You forgot a suicide letter?
Fiona: Well , I didn' t think I'd have to remember it, did I? Did you read the part where I said I'd always love you?
Marcus: It's a bit hard for you to love me when you're dead, isn't it?
Fiona: I' m sorry. I can understand why you' re angry, Marcus, but I don' t feel the same as I did yesterday, if that' s any help.
Marcus: What? It's all just gone away? All that?
Fiona: No, but at the moment, I feel better.
Marcus: The moment's no good to me. I can see you feel better at the moment. You just put the kettle-on. But what happens when you finish your tea? What happens when I go back to school? I can't watch you all the time.
Fiona: I know. I have to look after each other, the two of us.
Marcus: Suddenly , I realized: Two people isn't enough. You need a backup. If there are only two people and someone drops off the edge, then you' re on your own. Two isn't a large enough number. You need three, at least.
Fiona: Three what?
Marcus: Nothing. But I'd had a great idea.
