[General horror] How to pick a Final Girl/Guy

Hi, everybody. How are you all doing?

As a hideously deformed monster who was raised in a root cellar by his possibly insane grandmother, I was thinking I’d spend my summer stalking a random group of generically attractive high school seniors, brutally murdering them one by one in various creative ways – possibly involving farm equipment, I haven’t quite worked out the details yet.

Obviously my hideous spree of carnage will end when one of the last couple of survivors, ideally a wholesome yet emotionally troubled youngster who has managed to overcome past trauma in order to survive the horrors I have perpetrated, finally gets lucky, discovers my weakness (hint: there were no mirrors in the root cellar), turns the tables, and kills me.

But there’s a problem. Modern youth culture isn’t something I’m exactly in touch with, and I'm not sure how best to pick out which of the teenagers I should be stalking and menacing, but not actually killing until all the others are either dead or injured. I mean, according to grandma (who was kind of old-fashioned about stuff in general, and especially sex stuff), it should be a beautiful virgin, but that seems weird and sexist and all kinds of gross to me. Plus these days, at least if the media are to be believed, the odds of *any* of them being virgins are pretty slim.

So what kind of qualities should I be looking for in the teenagers while I'm watching them from the woods, following them to their cars, hiding in their attics, etc? What behaviors would mark somebody out as having the necessary qualities to be my Final Girl (or guy. I mean, I'd prefer a girl because I'm an old-fashioned kind of freak of nature at heart, but I don't want to narrow the field unnecessarily).

I don’t want to suddenly find I've dismembered the one member of the group with the right combination of moral purity and personal courage to finally end my reign of terror, but I also don’t want to hold back on the brutal slaughter of his or her less likable, but undeniably more interesting, friends.

It might be hard to spot, but pick The one that has The biggest potential for self growth. That way, you will make them discover their own badassery and will to live, and If you both survive this, it will make The next time you meet that much more intressting, when this battled harden survivor must try and protect The next group from your attacks, which will most likely take place is a asylum. People dont want helpless virgins saved by luck anymore, they want heros that stand victorious against The odds! It also gives you The opportunity, as a monster, to improve yourself and push your limits. If you are lucky, you and your newfound nemesis will get locked in a cycle of battle and growth, which just makes both of you more and more powerful. 

No, dont find a virign, find a Ripley.
