User blog comment:Superdawnfan/People Thought To Make Great Main Villains But Wouldn't/@comment-11883116-20161126214918/@comment-30651472-20161126223358

He is more of a loose cannon, but he still targeted most of his energy to Harold unlike Jo.

I can definitely see Eva being a henchman (not like Scarlett though) because of her interactions in Total Drama Drama Drama Island and willingly giving the case to Justin. In that sort of instance, the main antagonist, possibly Jo, would call her a mean nickname and/or punish her on account of her uselessness to complete her task. Even if she could usurp the main antagonist, I'm not sure that she would fare well late in the game (though she did do well in No Pain, No Game). Socially, I'm not sure she would be able to pull off a move like that, though I don't believe she would be as blind as Lindsay and Beth in TDI (minus their outbursts) since she is overly blunt, malevolent and bitter towards her fellow competitors.
