I am sorry to come back to this old and often-discussed question, but on my last playthrough, I suddenly realized that some dialogs point to the possibility of Gorion's ward being a shorty:
- The famous line of Imoen about ÿou grew fast", with the key-word "relatively" which could mean that indeed Gorion's ward grew but is still short
- One of the sentence of Tarnesh, when he speaks about the size of Gorion's ward, which fits what he was told. If he stressed the size, this may mean that it is peculiar - or small or big.
So I think this could leave open the possibility of Gorion's ward being a shorty. And of course, due to the age problem, the only real possibility is a Halfling.
What do you think ?
In fact, it seems to me that those sentences were placed intentionally to allow for the possibility of a shorty, but are fuzzy enough to leave open all the other possibilities. At the end of the day, what is important is the role playing of the character. I personally love playing Halfling female, even if I am a pretty tall man. A psychoanalyst would love this btw...
