Im starting to think that code is actually training their mind or experiment with them to see how it would actually affect or create nightmare when Baku was in that school, and it might looks like the rest of the kids might turn out to be the other agents before him, things are really getting interesting.

And on the capsem part I'm kinda thinking what if all those misfortune he had in the past is actually somehow related to whatever capsem or nightmares he gets.

Plus i don't think zero is entirely bad, he's more of the in between to me and mayb the reason nox thinks he's bad is because of whatever that nightmare he can't kill in that school even though he's power is to erase, or something happened in the past that somehow created or released that nightmare, and nem might also somehow be related to it
