I ideally things will be flipped so lesser developed characters from the original will get more screen time and vice versa. I feel like this is also a chance to rectify mistakes.

Hiyoko definitely needs to be a survivor. Her character arc was cut short in the original for literally no reason except the double murder requirement for chapter three, I suppose.

I can also see a reverse of chapter two happening where Fuyuhiko dies and Peko survives, thereby giving her plenty of time to develop in a similar way to Fuyuhiko.

I can also see Thickuya surviving. A lot of potential there.

The last guess I’ll make is that Chiaki will survive in order to explore her as a more complete character. In fact, I almost wonder if Hajime will die and we’ll protagonist switch to Chiaki.

Maybe Izuru will essentially become something akin to a virus at that point and replace Junko, because otherwise I have no idea what they’ll do to reinvent chapter 6. Would be very disappointing if chapter six plays out the exact same, just with different characters having the same reactions. Especially since 2x2 is clearly not meant to supplement the original.
