Caitlin. I already liked her and Darach in Gen IV, but I didn't think much of it. Seeing her again in Gen V was a nice surprise and it kinda made me like her even more.
As elegant and strong as Cattleya (Caitlin) was in Black/White, I would've preferred if Kokuran (Darach) had appeared with her in those games. Cattleya just wasn't the same without her butler.
