Yeah, Lin is a smarter, less head over heels Jenny :)
She wasn't actually meant to be a speaking character; like the other two gym girls she never got a talking head initially. But as I was rendering her I totally loved her look, and she convinced me to write her as a character of her own.
Snowdrop's quest-line's actually really good; it's probably my favorite so far. It starts off mindlessly enough, but it turns a little darker halfway through.
