"Kian, wait!" I've left Mathew in my study. He looks confused, but there was nothing else to say. I have to catch up with Kian. We need to talk.
He's reached the bottom of the front steps. I race down the corridor - a pretty great impression of Doctor Who's companion, I think - and slam open the door. "Kian - wait!"
"Haven't you done enough?" he says, turning those dead eyes on me. Oh, man, I've done something terrible.
"We need to talk."
"I think you've said everything that needs to be said," says Kian, looking at me with animosity. And then it explodes. "Don't you know how it feels to discover that everything you've ever faced was only invented by an author? Don't you know how it feels to realise that none of it mattered? Don't you know how it feels to have been bloody spied upon for your whole life?"
"I haven't spied on you!"
"You've watched - you decided my every move! You know my thoughts and dreams, my hopes and fears. I call that spying!"
"I'm sorry - I didn't mean to ruin everything. I've been so stupid..." I stare at the floor, but force myself to meet his eyes. "I didn't mean to blurt it out like that. You had to know."
"No, I didn't." For a second his anger flares, but he calms himself. Now he is merely sad. "Can't you imagine what it will be like for me to live my life knowing that I'm going to die?"
"Everybody is going to die," I point out, but it's too late for that now. I point to a vending machine, back inside the safe, glass doors of the building. "Can't we discuss this over a cup of hot chocolate?"
I can see from his expression that he doesn't have a clue what I'm saying. "Forget it," I sigh. "I'll see you around."
"No you won't," he says. "I'm dead."
"Ah, but you appear in Oona's dreams in the third one..." I grin, but it quickly fades. "Not the same, is it?"
Kian shakes his head and starts to walk off.
"I can rewrite the final scene! It doesn't have to happen!"
"No," he says, turning. "It will happen. You said it yourself - everybody has to die at some point."
