Can someone tell me what the sheriff's son and his girlfriend have contributed to the development of the story? They take up a lot of screen time but what exactly is the purpose of their roles? Because it really doesn't make any difference with or without them as far as the story goes.

Annnnnnnd even more questions. Great. Also, nothing in this episode made any sense. The randomness of this series is infinite. And I believe that every revelation, every plot progression, will continue to be random. Because, after two whole seasons, NOTHING is connecting. Nothing. Dear creators and writers, if there’s another season, please give your audience some effing payoff for once. It’s getting ridiculous.
