I really do not want to look at it again, so there might a word or two that are different, but it's basically the chat that has been posted here several times from other media, he doesn't really say kid, he said "I want to ... something little" which sounds even worse. And he says he will film it and document how he is torturing her. The other person says "cool". And in the end he says "yeah, but now do it and not just talk about it, hehe".
This is a very dangerous and sick sadistic psychopath. Disgusting.
