Over at the church, Father Bonilla is singlehandedly keeping Los Angeles warm with all the candles he's burning. The phone rings. "Buenos dias, Father," says Cameron's voice.
And then Aldridge is leading Father Bonilla down the hall to Sarah's room. She's surprised to see him, and asks if he passed on the message. He did, but they've got a message for her: "She's coming." Before Sarah can even react, there's a siren in the distance. He frantically tries the door handle, but it's locked, like, it's a JAIL, Father. He says he doesn't know what to do. "You're a priest. Pray," she tells him.
So what's a Terminator incarnation without an assault on a police station? Cameron calmly strides through L.A. County Jail with a shotgun shooting at many guards, but not actually hitting them. She hits a light fixture that swings down and beans a guard. She's avoiding killing them. They, however, are throwing everything they have at her, and all seem to be armed with submachine guns.
John Henry watches the carnage with interest. On another screen he brings up the jail's electronic lock subsystem. In Sarah's interrogation room, she notes the green light on the door handle and asks Father Bonilla about the Bible story where the locks fall off. "Peter," he tells her. "Gird thyself," she says. Sure enough, the cell doors are sliding open across the jail, and the prisoners are spilling out into the corridors, like students on the last day of school in a summer comedy.
Cameron's still making her way through the jail, although now half her face is blown off. She can probably brush her bangs down, though, and no one will notice. Barely anybody seems to notice her anyway, in all the general hubbub. Weaver comes in and says it appears there's been a bit of an incident. She asks if he knows how it started. Yes, John Henry tells her, pointing out Sarah and Cameron in the security footage.
The two of them meet up. "You look like hell," Sarah tells her, when I'm pretty sure a simple "thank-you" would have sufficed. She asks if Cameron can keep up, and Cameron just breaks her handcuffs in response. They make their way outside, where John pulls up and the women climb in, and they go busting through a gate in this ridiculously unsecure, unguarded prison.
