Evil twins of destruction, merely getting fun out of torturing and killing humanity. 18 loves the destruction but 17 loves to get more enjoyment out of it.
18: I think it's time to put them out of their misery, 17.
17: Why are you in such a rush? Let's just try to enjoy ourselves. If we wipe out all of humanity now, then the fun ends and there's nothing left to do, right? I'm 17 and this is my sister 18.
