As we expected, Joe Carroll escapes from prison while he's being transferred from Virginia to Georgia on account of how this one time Ryan broke three of his fingers and that violates his constitutional rights even though Ryan doesn't work for the prison or the FBI or anyone in a position of authority over Carroll, actually? At the most it sounds like he's guilty of assault. Whatever. IANAL (and no one else is, either).
The warden helps Carroll stow away in Eight-Fingered Olivia's trunk—because Tangential Follower Bo abducted the warden's daughter and is keeping her in a cage like a corgi—and for her trouble, OctoLawyer gets strangled to death, in her own car, in broad daylight. Eight more reasons not to go to law school!
Over on the inept FBI side of the aisle, Ryan and Mike spend the entire episode scampering after Carroll, always just a minute too slow. They have to listen to Carroll killing Olivia, and then they chase him through a crowded mall and a parking garage, where Carroll meets up with new follower helpers David and Louise. Louise and Carroll escape in a tiny helicopter while David, ever loyal (well, five minutes loyal, since that's how long we've known him), takes a bullet from Ryan and then lets him work out some of his frustration with Joe's blatherings via torture for information.
David's information leads Ryan to the basement lair where Emma and Joey met up with Charlie and new follower Bo. Bo is the one who kidnapped the warden's daughter and crated her, and when the serial killer's other followers think you're unbalanced and weird, maybe you need to stop locking liberal arts undergrads in cages, hmm? Anyway, they rescue Dana. Her dad is going to jail forever for helping Carroll escape, but she's fine.
Carroll, Louise, Emma, and Charlie all meet up at the cult's headquarters, which looks like a college dorm. And this is where Joe reunites with his son. Creepily. As if he can act any other way.
Previously on The Following: This show was supposed to be a 15-episode one-and-done, but then Fox got all greedy and renewed it, so you know Ryan will never actually have that heart attack/get stabbed in the face and Carroll will never get caught and WHAT IS THE POINT?
Emma and Joey pull into a garage in their Ava-provided SUV. Joey's asking for his mom, and then later for Jacob and Paul, but Emma tells him they're meeting a friend. Eventually she gets fed up with all his questions and hushes him. Emma knocks and a man with a scar on his face and a neck tattoo introduces himself as Bo. Emma sends Joey off to the restroom by himself in this horrible place (although it's helpfully marked. You don't want any confusion in your creepy dungeon). Right across from the bathroom door is another door that's chained shut, but not very tightly, because Joey's able to push it open enough for him to get in. He walks into a room full of cages. A woman in one of the cages begs him not to leave her there. Joey flees. As would we all.
Carroll, his lawyer and some authorities from the prison watch the video of Ryan breaking three of Joe's fingers as OctoLawyer Olivia cites all sorts of amendments and precedents. Carroll starts speechifying pompously and I will only be satisfied if this show ends with Carroll getting his stupid tongue cut out.
Claire is telling Parker about Charlie and her idiotic kidnapping. She says Charlie had an "honor" about him, if by honor you mean total crazy eyes. Ryan comes in and hands her a cup of tea as Claire is telling Parker about Roderick and the connection to The Fall of the House of Usher. Ryan mentions that Emma got a call from Roderick at the farmhouse, and Parker speculates he's Carroll's field marshal. Claire asks if they know how many people are involved, and if they're fans or groupies or crazy people, although it seems obvious they're all three. Parker asks if they can trust her not to run off with more of Carroll's minions, and she says they can't, any more than she can trust them to find Joey. She has a point there; Ryan and Parker are TERRIBLE at their jobs. Parker wanly asks her to tell them if the minions check in again. At no point does Claire mention that it was OctoLawyer who connected her with Charlie, but she does tell Ryan he needs to find Charlie because he knows where Joey is.
Garage. Emma asks Bo when Charlie is coming. He doesn't answer, but then Joey reappears, looking stricken. He tells Emma about the woman in the cage, and Bo yells at him that he wasn't supposed to go back there. Emma stands between the hollering man and her bargaining chip, and it's kind of about time Joey got scared? Like, he's not a very smart kid if this is the first thing that's worrying him. Emma asks Bo about Cage Girl and he tells her to shut up and wait for Roderick/Charlie/Godot/whomever.
