So I have a habit of making theories about stuff. Even this-

(Warning: Spoilers Ahead)

SO I've been thinking about how seven died.

He died from the poison because he performed his forbidden action.

The story the group came up with was "the killer tried to stab him with the knife causing him to perform his forbidden action which was hitting someone"

Makes sense, right?

WELL IF YOU'RE AN OVER THINKER LIKE ME, THIS RAISES TONS OF QUESTIONS.

Seven was stabbed in his back. He's a pretty big guy, the cut wasn't very deep, and last time I checked there aren't any vital organs in your back. So there is no way the killer could have expected to kill seven just by stabbing him. It would not kill him fast enough, and they would get noticed right away.

In order for that kill to have been successful like it was, they would HAVE to of known what Seven's forbidden action was.

Same with how Joshua died.

The killer pushed him into a wall, and Joshua's forbidden action was to touch a wall.

Which leads me to think that

1) Seven and Joshua had the same killer

2) Their killer knew their forbidden action before hand.

But if any of you have watched the council of voices, you know that the group decided to keep their forbidden actions to themselves and not tell anyone else what they were.

So how could their killer have known their forbidden actions?

The only thing I can think of is that it was because the killer gave them their forbidden actions. Aka, the killer must be Zero.

Now I have no clue who Zero could be.

It could be one of the participants from the nonary game or somebody from the council.

It's highly unlikely that's it's someone who hasn't been introduced, due to "The Bad boyz's" Discovery of an extra set of prints coming back from the council building than there were going in.

ANYWAY THESE ARE JUST MY THOUGHTS AND THEORIES, THEY ARE PROBABLY SUUUUUPPPPEEERR WRONG AND I'M JUST OVER THINKING BUT WHATEVER THIS WAS FUN TO WRITE.
