"Don't tell anyone, but, I don't know why I've asked. I really don't know. Something's wrong with me, sometimes. I - I should do something about that, but I just don't know what. I don't want to worry my friends. I'm sure you understand."

"Stockpile? Huh. As long as it's not from killed people."

Now that was rude, probably, unintentionally, but that was all him, since they're now talking about the subject anyway.
