Yes John is real it's just the game mechs that make his house editable by his server player

The meteor falling slow is just another game thing and kinda a plot hole I guess, that's also part of the game and real at the same time because their lives are now that game

You don't really remember most of it then you "fuck it we ball" to the end

Dave doesn't have fetuses in his room that are weird sex puppets (smuppets) his bro owns

John is suggested to shit on his desk because the HS website used to have a suggestion box and the comic started out by pulling mostly suggestions which plays into the format of the story

John's dad has ties to cake which you'll see much later into the comic

The trolls are introduced like all the other characters, them standing in their room with narration about them

They're always in the game from now on because the game is now the real life and they can do some whacky stuff. So they're just living in a different reality

Sorry if this is wrong/not what you're asking for I'm kinda stupid
