I have a theory of how SnP may twist/justify Harper being a miserable cunt. If she writes Harper as the "Evil" system member, or the persecutor, that makes it excusable, surely. There's no real positive way to portray Harper. He was a sexpest on meeting Kai formerly, he belittles Piper's role and ability to recall information, he actively will abuse that knowledge to get out of explaining Quinn beating up Kai. Something rubs me wrong, too. There's an air of superiority or maturity to Harper that feels more like he's written as an adult. The other characters act like children, including Quinn, but Harper doesn't and is actively malicious. I hate this guy.
EDIT: grammar
