Both Jordan and Mimi. I don't feel like Zach (which is ironically my name) has too much of a backstory to tell because it was pretty much Juniper giving him to Nina and that's about it, at least as far as I can tell.
Yes! Voting powers achieved! 1/74th of decision making influenced at the time of posting. I would have to say Mr. J. He has an interesting character, diving deeper into his past could be a lot more interesting, seeing that people are attracted to negativity. Go forth and elaborate!
I think the major question posed to us all is "Why is Jordan the way he is? Did something happen in his past that made his personality the way it is? We know he's a tough guy, but he has a heart (somewhat). Can you elaborate on this?" It will be fascinating to find out anything.
