From his office, Col. Broyles leaves a message for his wife on voicemail, and then immediately answers his phone, thinking it's her. But it's Olivia (so good thing he didn't make his voice go TOO sexy), still dockside, telling him that she thinks they were wrong: "Wyatt Toomy was not a scientist. He needed someone to show him how to make the serum," she says, and I hate to think that Broyles is dumb enough to say, "Who?" but he does and Olivia says that Reverend Marcus was a doctor, and this is how he's been healing his congregation. Broyles is all "dear God" and then he's up and going, because Reverend Marcus knows Chris can identify the voices, and now Diane isn't picking up the phone.
Olivia says she'll meet him there, and then pleads with Henry to wait for her while she goes and does something. He does NOT seem pleased about it.
Over at the Broyles compound, Christopher's awakened to the sound of his mother screaming, which is understandable since she's being chloroformed by a masked Reverend Marcus.
Once she's knocked out, Toomy starts wandering the house, looking for Chris, who has ditched his bed and is now hiding inside a cabinet. Unfortunately, the front design features hundreds of quarter-sized holes. Still, it's dark, and Marcus seems not to notice on his first pass, and maybe he's too distracted by all the stuff he's yakking about. "God wants me to find you. I'm simply carrying out his plan," he says, and suddenly he yanks open the cabinet and grabs a screaming Chris, who struggles, refusing to let Marcus chloroform him. And then Broyles is there, and he coolly fires off a shot, dropping Marcus like a sack of potatoes, and then Chris runs into his dad's arms and they hug tightly. Broyles smiles. Behind them, out of focus, Olivia walks in, hopefully not pissed that she didn't even need to be there.
So then everyone's laughing and haven't a grand old time at the hospital, with Olivia, smiling, watching the Broyleses (?) -- including a now-conscious Diane -- laugh with each other while a nurse tends to Chris.
She gets a call from an anxious Henry and tells him she'll be there in fifteen minutes, and then she's approached by Max's mom, who says the doctors think they got to Max just in time. "Now, he hasn't been able to stop talking about you," she says. I bet! She says it would mean a lot if she could stop in and say hello, so Olivia does that, visiting a thrilled Max.
