I think that was mentioned in an interview somewhere too.

I didn't see her as the same character who had written the diaries - although they've changed those recently and now gell better with the character on screen. I know what you mean about different people appearing different ages, but she just seemed too consistently young to me (then I am ancient and will shortly be hitting people with a stick and saying "when I were a lass.."). I couldn't gell her level of niavetiy with the life she'll have lead in the road house - a roughish bar full of hunters who she hustles? - as younger she did totally work for me though so I can work that in my head if I have to :D
