OK, it's been a while since I played the game, and I'm not one of those anal people who memorize every word, but, if I remember correctly . . .

The first time you see Krile, it is in Galuf's memory, and she is 6 or so then. When you actually meet up with her, she has the same sprite. So, I can see how people would misunderstand.

Either that, or she bears some weird unknowable resemblance to Eiko.
