Scully and Doggett bring Greasy into the station. Scully tells Doggett to chill, and explains that Greasy couldn't possibly have taken Billy, because she saw Billy enter the house with his mother not five seconds before Doggett saw him in the car with Greasy. She sort of loses it, and about time, too, telling Doggett that everything about this case is "impossible," and he needs to deal with that. "The kid is the key, Scully!" Doggett hollers, and before he gets into with her, the sheriff opens the door and tells them that Josh has gone missing, and he's got the Underwoods outside. Scully rolls her eyes. Doggett stays behind to talk to Greasy. She gives him a dirty look. He looks pained. I make a sandwich.
Doggett takes Greasy to the interrogation room, where Greasy tells him that he has no answer to Doggett's questions. He doesn't know how Billy got in his car, and he explains that he went to the Underwood house because he didn't believe that Billy could possibly be back with his family. Because, you know, Billy is dead.
Flashback to the Carnival of Evil. Greasy looks furtive.
Doggett asks Greasy where he kept Billy "all those years."
Flashback to poor Billy under the slats of the floor of what I guess is the pony trailer.
Greasy spits that Doggett really, really doesn't get it.
Flashback of Greasy singing to Billy. It's the creepy nursery rhyme on the tape. He tries to untie Billy's bindings with our old friend, the hunting knife.
Doggett asks Greasy what he did to Billy. Greasy didn't do anything to Billy, he says. He took care of Billy. He sang to Billy, so Billy wouldn't be afraid. "Afraid of who?" asks Doggett. "Did he take Billy's brother, too?" Blah blah, Greasy is a victim, too. Doggett manfully informs Greasy this is "his chance, man," and asks for the kidnapper's name. Greasy sways and gulps.
Police car upon police car pull up outside the Trailer of Love, near where, helpfully, is parked the pony van. Inside the pony van, under the floor, of course, is poor, poor Josh, still alive, but sweating bullets. Outside, Baldy books for the woods. Doggett races after him, the police right behind him. Much trampling through the undergrowth ensues, until Doggett catches Baldy, points his gun at him, and demands to know where "the kid is." "In the trailer," Baldy says, really calmly. "The other kid!" Doggett spits. Baldy looks perplexed. "There is no other kid," he says. But, of course, Billy is standing right behind Doggett. Then he's not. Of course. The other cops cuff Baldy and read him his rights, as Doggett stumbes over where Billy had been standing and finds, of course, a child's skull. He looks stunned.
