I don't care for Jane, she seems like a self centered person and a bad friend so I wouldn't be interested in a friendship route. That being said, if fans really want it, it's no big deal if it gets in the game. I can only hope that if she does get a route it gets done after all of Isaac's routes since he's the reason I'm playing and I have no interest in Jane aside from her being a side character. Love the game! <3
