Finished this the day he posted it, but got distracted introducing myself and poking around when I came to put it up here, and forgot. It's here on my blog:

"The world is full of decay."
"We shouldn't add to it then."
"It's not our decision."
"Then who's is it?"
"You know."
"I don't know."
"No, you know. Don't make me say it."
"But I don't know!"
"It doesn't matter Charlie, we need to do our job."
"For a boss I don't even know?"
"Yes. Do as I say son."
"But not as you do, right? You do it. I'll walk home."
"You cannot do that."
"Why not?"
"You are not old enough to be on your own."
"Oh really? Then why did you lie to Mom?"
"I needed you on this mission."
"Don't you have a partner or something? I thought you were a cop."
"Not exactly."
"What are you than?"
"More like what are we, my son."
"I don't work with you. I'm thirteen. How could I sign up for this?"
"You did not. It is who we are."
"Couldn't Mom help you instead? She's great at killing things. You've seen the garden."
"Your mother will have no part of this."
"Than I won't either."
"You have no choice."
"Why? Because you say so?"
"No."
"Then why?"
"I cannot tell you. You must figure it out on your own."
"Is this some sort of test? I don't do well on those, you know."
"It is not a test. But everyone in our condition has to find their own reasons, their own why."
"It's so beautiful Father."
"I know."
"Can't I keep it?"
"No. Think of how much I am gone. Could we keep all of those? It would not be fair."
"Well, you always say the world's not fair."
"Take it son, your mother is expecting us for dinner."
"I don't know how."
"Touch it. You will see how."
"It's smiling at me."
"It does not belong here, son, do the job."
"I don't want a job!"
"You have as much choice in this as you did in your sex, boy, now do it. I cannot stand to hear it much longer."
"She's laying down, Dad, she knows what's coming."
"Always remember what it is son. Always."
"I don't know what she is! I just know she's beautiful!"
"You have to do it now son."
"Don't touch me! Murder her yourself!"
"Shake it off son. It will all be clear. Let her go."
"No!"
"You have to do this. You chose to care for it. I told you to close off your mind."
"I won't! You'll have to kill us both!"
"Please don't make me end it, my son. Find your power, end it yourself, please."
"You're choking me!"
"You must see reason. Take its life. They cannot be allowed to stay."
"But-she's-so-beautiful-her-mind-the answers-"
"Do what you have to do or I will have to."
"All-right-father-I-see."
"What do you see?"
"The poisoned-heart-it's-black-I'll-"
"And what do you see now son?
"The world is full of decay."
