Mike gets Jessica's husband, Gary, sprung from prison so the two of them can scour Ms. Booth’s place for clues on Jessica's death. And we know the place is full of them.
While poking around Booth’s backyard, Gary finds some loose teeth on a post. What does it mean? Also, there's a high probability he could sell these (people sell teeth on ebay. For real).
Flashback: when Mrs. Booth was having one of her seizures, Eddie was able to use his telekinetic powers to stop her. Looks like one student is due some extra credit points.
Mrs. Booth lures Mike to an out-of-the-way strip mall with the promise of more information about the Candle Cove goings on. When he gets inside, he realizes it might have been a trap.
Attempting to get out of Iron Hill with her daughter Lily, Erica swerves to avoid some brainwashed kids and ends up wrecking her car. That’ll teach you to swerve!
Mrs. Booth has a heart-to-heart with Marla and Mike (while pointing a gun at them), and she tells them that Eddie created Candle Cove. Booth became an Eddie convert when his telekinesis stopped her seizures.
Turns out, a much younger Ms. Booth “fed” her son to the “fire” that was Eddie so that he could “burn” more brightly. Meaning create Candle Cove. Yes, Mrs. Booth murdered her own son.
Mrs. Booth tells Mike that Eddie wants to return to the corporeal world....through Mike's body. Hence the extra tooth (something Eddie possessed) appearing. Mike, naturally, decides to rip it out.
