I don't see much point in creating Sasha scenes more or less with just different head. Creating a new worthy scene for her involves lot of skilled drawing and time consuming animation. I doubt we have enough time and skills for that.
I would go with making player think that she has a sex scene and just get different excuse in each dialog branch. Of course not everyone will like this sort of prank.
Regarding bug report, I would like to get HTH beta v0.3 bug report and suggestions first because I see it almost ready for release. I would like to get it finished finally.
