Fire emblem games tend to over-exagerate the gimicks of their characters, and apparently the messed up american translation of Fate doesn't help at that and replaced many diversified lines with generic things like that.

Which is a shame, especially when most of the time, their battle or daily life line don't change. I'm still sorry for the people marrying Cordelia in Awakening that are remembered in a regular basis that she still desperately wants to bone Chrom.
