When I first saw her I thought the same thing, my initial thought of her was and I quote my own thoughts "Wow that chick at the far right looks like total trailer trash, totally different from Bree and Sasha art style wise"... Then I played the game, encountered her and... she actually is trailer trash LOL... So it fit for me...
For a while Aubrey and Anna also looked very different for me as they seemed more "cel-shaded graphics vs Sasha and Bree's more 2d hand drawn style... eventually they all grew on me... The ones I think I still struggle with but might also grow on me are the church girl, and the ex's little sister, they look like from a different game for me... then again they both showed up for like half a scene only...
