Why I am a die-hard believer that Whit is the mastermind
You know I was going to make an entire structured theory thread about it but Tumblr decided to be a little bitch and remove all my writing so I'll just kinda throw a messy list of evidence here.
Notice how Veronika's summary of Forever Dead is suspiciously similar to the secret dialogue
Notice how the main character's gender is pointed out
It's also interesting how the mysterious dialogue in the beginning who seems to be related to the hidden text (the idea of not being able to remember anymore link those two) seem to often mention the fact that they're grieving the loss of someone.
That someone most likely being Mai who seems to have suffered a tragic fate due to Teruko, which can explain the mastermind's hatred of her.
Guess who's character is linked with grief ?
(I know this is most likely about his mother but there is nothing contradicting the fact that he could be idolizing multiple dead people)
Wow it's interesting how these secret texts about Mai seem to be really idolizing her.
We can also add how the person who wrote the note to Xavier is very clearly the mastermind and how Whit's tool is a Stationery (it's spelled Stationary but i believe its a typo) which is commonly known as writing and other office materials.
Which includes paper, pens, ink, highlighters and other tools for writing
It's even made worse by the fact that the note seems to be written by a specific type of blue pen that we haven't seen anywhere in the series.
And even worse is that Charles, who knows Whit's handwriting, couldn't point out the writing is his as he couldn't access the scene of the crime due to his trauma therefore he couldn't see the note's handwriting.
It's really really interesting how the hidden text points out how they can predict everyone's behavior in a killing game and Whit's intuition is highlighted three times in this game.
Another suspicious thing is how the mastermind of the game talks about how they basically can predict anything that can happen. It's almost like how Whit jokingly predicted Arei's death.
Along with how Whit is the only one who has directly talked to the audience (him showing the papers) or how he's nudged the killing game into more interesting directions/avoided it from going off the rails.
Other exemples would be him defending Teruko/Charles in the first trial, him not revealing David's secret until the last minute (as well as the note that suspiciously pointed to Eden), him not trying to help with the fight in episode 4, him insisting that Charles and Teruko talk about their family life (aka nudging them to talk about their backstory which would entertain the audience) and other stuff i don't feel like adding.
It's also important add that Mono-TV and Whit also have similar personalities. They both don't take anything seriously and make constant jokes about the killing games, Mono-TV and Whit also act constantly incompetent and like they're a lot dumber than they actually are.
Another thing is that it's interesting how Whit opens up about his secret so easily, even though almost everyone's secrets are something they're at least flustered about and at worst completely ashamed by. If he was the mastermind, it would make sense that his secret wouldn't be anything that could ruin his character and that he could just admit easily.
Also another point, the mastermind character talks about a time when they cared so much about people and how it hurt them so much when they died. Which you can see that caring nature shine through a lot with Whit as it's possible that Whit's personnality is not actually a lie but more so a reflection of how he used to be before he went through all this alledged horrible stuff.
We can also note how the mastermind has to be one of the students and how there is an extreme likelyhood that Mono-TV saying it isn't bait because it's not actually told to the students but to us. Why would Mono-TV tell it to us and not to the students if it was a lie meant to make the game more interesting, wouldn't it be more entertaining to reveal to the students of a fake mastermind among them to get them to kill one another more easily. It's why I have no doubt someone in this class has to be the mastermind behind it.
Mono-TV also seems to not have any contact with the person controlling him which would make sense if it was someone in the killing game as they would have a hard time communicating without being caught.
(It's a stretch but it would make more sense if Mono-TV didn't know if the mastermind was one of them as if the mastermind was behind the scenes there would be no reason why it wouldn't interact with Mono-TV, although take this with a grain of salt as he could be lying)
And just really there aren't a lot of other options for the mastermind that would be compelling unless they introduce a mysterious new character.
It could be the mysterious red haired girl but everything hints towards her being dead or hurt and it being the cause for the killing game rather than her being the one behind it. There is some decent evidence that it could be her but I genuinely don't think so considering it again feels a little too obvious and doesn't work with how the story/secrets present her.
(It's just not very compelling to make your ONE mystery character the mastermind and again it would be weird considering Mono-TV telling the audience the mastermind is in cast doesn't make sense logically as he would have no reason to try and trick the audience)
Not a lot of characters in this cast can be really put into the mastermind category as they are either too obvious (teruko, veronika) or too farfetched (eden, hu etc...).
I honestly am a die hard believer that Whit is the mastermind however what's interesting to me is not If Whit is the mastermind but more so the Why ?
Which honestly might be a question for another time...
But yeah this is why I 95 pourcent believe Whit is the mastermind
If anyone has anything more to add I would be really interesting in seeing what other people have in terms of evidence.
