Woaah, that's a lot of thoughts! First of all, I want to say that many of the things you didn't like will only make sense once the entire game is out. As they say, it's hard to judge an unfinished story. That said, I completely understand why some moments might have felt confusing to you! ^^
The only thing I can really say is... keep following the story and pay VERY close attention if you want to understand the story.
Also, you sure this is actually out of character for the MC? How much deduction have they used in previous chapters? Have they really been taking an active role and initiating all of the discussions? I’d recommend replaying the first two chapters to refresh your memory, because things are faaaar more complicated than they seem muhehe! 😉
It's okay, I completely understand! MtG still has a long journey ahead of it, along with plenty of answers to many of the questions people have. I'd love to reveal all my cards and explain everything right here and now, but where's the fun in that? So for now, I'll stick to my terrifyingly slow-slooooooow buuuurn 😈
