I like how Betty forced Monica to shave herself. She looks a lot better that way.
But, I've noticed from playing some early saves (to unlock gallery pics) that she's depicted as being shaved (like while she's in the shower or coming out of bed), even when that rule hasn't been given to her yet. This is essentially from playing a new game, before there's been much story progress, and in some shot's she's shaved. So, maybe the dev needs to put some checks in to determine if she should appear shaved or not, depending on if that shaving rule has been given? Just a thought.
I already said I like Monica that way. But, it's a bit odd to see these nice pics, and then her once again with hair.
