Warning: If you don't want to know what happened in this episode, don't read this photo recap!
Mike Painter is an esteemed child psychologist with a terrifying past that gives him terrible nightmares. When he was a child, his twin brother was killed, along with four other kids, in the Iron Hill Murders. Someone page Dr. Freud.
While conducting a formal search for Katie, Jessica and the police are beginning to grow suspicious of Mike and his interest in "Candle Cove." Also because he didn't get home until 3AM the night before. He should have used Google maps.
We get more information on Mike's past. Some time ago, he carved "Mike Come Home" into his arm with a screwdriver, and committed himself to a psych ward, from which he's just been released. We'll see how this plays out.
In a flashback to 1988 we see the Painter brothers watching Candle Cove. And the thing about Candle Cove is...apparently, there was no such thing as Candle Cove. It was all just a bunch of black and white static.
