Common 2P! Traits
It is common for the Second Player to be portrayed as murderous, sociopathic and possibly insane. To most, they are a darker version of the original Nations. However, because the Original Nations can be portrayed the same way by the fandom, how much hold this has depends on the person making the story. Wy will whack you with her cane, and probably try to stab you.
