I like the fact that the discussions we can actually read have nothing in them that would directly help us understand what Mary is saying or what he's hearing. It's all either unrelated or only hints at what might've been said. It's a great way to add some voices and characters to the story without undercutting the basic premise.
Also, can we get a mod in here, or can one of the arguers be the better person here and take the conversation to DMs? A public forum like this is not a good place to resolve arguments, by it's very nature. Much easier to talk stuff over and resolve things in private. And this just isn't the place for the discussion anyhow, chapter discussion threads are supposed to remain about the manga as much as possible. Once you're not even discussing the chapter indirectly and are just fighting each other, it's really time to pack it up.
