I'm not sure how early she was scraped. If it was too early, there could be characters who are in the game because she isn't other than Halsin. There was another one who didn't make it in, I believe. They could have been intended act 3 companions instead of Jaheira and Minsk. Just as an example. They could even have had too much story in the upper city to be salvageable. I would be making random guesses
