Olivia's in an apartment building, on the phone with Broyles, saying she hasn't had any luck yet but the church is full of true believers: "One guy actually told me that the reverend cured his kidney disease," she says, strangely dismissive of the claim for a person whose working theory is that another person in the same church is literally reversing aging by stealing pituitary extracts from young children. Apparently Lee and Charlie aren't having any luck, so Olivia tells Broyles not to worry, because the cameras are back on her now, which means the next person is going to be the guy they're looking for.
She knocks on the door, which is opened partway by a man wearing black, including a baseball hat covering what appears to be no hair. He nods when Olivia asks if he's Wyatt Toomy. She identifies herself and says she needs to ask him a few questions, so can she come in? Toomy lets her in, and we skip ahead a moment to Toomey looking at a picture of Max, saying he saw him on the news: "It's real sad. You really think someone from the church may have taken him?" Olivia says it's possible.
Toomy gets his dinner from the stove, asking Olivia if she's met Reverend Marcus, and then praising him as a miracle worker as he walks into his dining room and puts his food on the table. Then he spots the child's doll across the room, and Olivia sees it too. He turns to look at her, sees that she's noticed it. "Do you live here alone, Mr. Toomy?" she asks. "Yep. Just me," he says, slowly, and they stare each other down for a moment before Olivia orders him not to move, and she goes for her gun. And Toomy TOTALLY moves, making a break for it and slamming a door in Olivia's face. She calls for backup and chases him, and as she makes her way through the apartment she finds a curtain covering a hidden door in a closet. On the other side is a hidden room, filled with gadgets and scribbled walls ... and then weak little Max, lying on the bed. She goes to him and tells him, "I'm with the FBI. Are you OK?" she says, and I have to confess that her saying "I'm with the FBI" didn't twig with me at all the first time.
