Ok hi tumblr I never post but I wanna drop my 2 cents in on ch 335…so spoilers ahead.
BASICALLY, we all know that Hagakure being the traitor was underwhelming (maybe a bit surprising at best) but she makes the most sense to be the traitor.
((EDIT: LMAO THIS AGED BAD. BUT ILL STILL LEAVE THIS HERE BC ITS STILL AN INTERESTING THINK PIECE))
Out of everyone in 1A, she’s had the least screen time, the least amount of interactions with everyone, and she’s always the one not a part of the action. She is literally detached from us as an audience and the class. She’s been kept at a distance from us on purpose. We were never meant to pay her any mind and that’s what makes her such a good candidate to be a traitor.
With Denki (the most popular choice for being the traitor) he’s never really given us any reason to not trust him. He’s actively engaging with his classmates, he has a close relationship with the main cast, and he was key in helping fight in the war arc. Plus we get to see him get really close with people like Jiro, Kirishima, and Bakugou. We as an audience formed a connection with Denki and we know that he cares a lot about his friends. (This all can be said for Kirishima as well)
Hagakure on the other hand has never given us a reason to trust or not trust her. She’s always been in the background.
But that’s not all, what’s been pointed out by many people are two key events in the early arcs: the USJ incident and the mall incident.
In the case of the USJ, Todoroki comments he never heard or saw Hagakure where he was fighting. Which ok fair enough, he didn’t see her. But we’ve also seen her talk so people know she’s around (I.e the early training arc). So why wouldn’t she want to make herself known so Todoroki doesn’t accidentally freeze her?
As far as the mall incident goes, she’s the one who points out that they should go there in the first place. And what happens? Izuku is conveniently approached by Shigaraki. How would he have known to be there?
So yeah. Those are my two cents. I’ll probably add in if I think of anything else.
