Why is every character in Mystery so retarded? They know X is hiding among them so what do they do? They give X a bomb detonator to threaten Eva with.
And when Shouma says X wore a long, black poncho. They still couldn't figure it out when there's only ONE FUCKING CHARACTER WEARING A PONCHO.
And to top it off, they don't even figure it out through deduction, they just see X leaving from a secret door and go "OH MY GOSH IT'S X"
God I hate this fucking route.
