"You wouldn't dare! John, I'm warning you, if you throw me into the sewage, you're dead!"
"Watch me! You think you can control me, you pathetic remnant soul? I don't need you to tell me anything! You've been playing mysterious games, not even revealing who you are. Do you think I'm easy to bully?"
John half-squinted his eyes and flicked open the Eternal Alchemy Bible in his palm, threatening, "I've realized I've been way too gentle with you. How did I let a dead soul manipulate me?
Do what you want, you can choose not to cooperate. I'll accept not learning alchemy. But I'm not letting you control me anymore! No more of your conditions!"
"You insolent brat! Do you know who I am? How dare you speak to me like that?"
"Yes, like this! If you won't cooperate without threats, I won't humor your whims. You can choose to stay silent. I'll just put you in storage!"
With that, John crushed a teleportation scroll.
