Monroe sends Neville off to pick up a package for him, and tells him if he fucks up again—his first two strikes were killing Ben Matheson and not killing Miles Matheson, respectively—the general will be even more pissed off than he seems to be all the time. The rebels blow up Neville's convoy and take him prisoner, so he's just having a really bad run of luck, you know?
Rachel wants to kill Neville immediately, while Miles wants to hit him with a hammer until he tells them everything he knows. But the mastermind of this week's grand plan is Jason, yes, dumb stone-faced Jason, who fools his father into telling him where he was going by convincing him he's going to free him so they can go save Julia, Tom's wife and Jason's mom. Because when Monroe finds out that Neville's screwed up again, he'll kill Julia. But Jason just tells the rebels Neville's goal and leaves him locked up. Which wasn't much impediment, as he gets free, kills Nicholas, and escapes to find Julia and convince her to go on the lam with him.
Since Neville failed, Randall retrieves the package Monroe wanted: it's a nuclear bomb. So the rebels set out on two missions: Rachel has told Aaron what caused the blackout, so they're bound for the west and the Tower, where they will try to turn the power back on. Miles, Charlie, Nora, and Jim are set on stopping Monroe from turning the entire eastern seaboard into a smoking crater.
Previously on Revolution: Neville tried and failed to kill Miles, then disowned his son for not being enthusiastic enough about massacring innocent people. Danny got himself killed, so Charlie and Rachel are out for Monroe's blood, and Rachel finally started to tell Aaron about how she and Randall caused the blackout.
Philadelphia. Monroe finally admits Neville into his presence, after making him wait for an hour, because the Monroe Republic adheres to the same subtle social cues as the folks on Downton Abbey. Inside the office, Monroe tells Neville that he and Randall were discussing sending Neville to retrieve something important, although Randall throws shade about whether he's capable of this simple task, then smilingly recounts Neville's fuckups: killing Ben, letting Miles get away. He says if Neville worked for Randall, he'd fire him. Neville grits that he doesn't work for him, and calls Randall a civilian in a cheap suit. Randall, outraged, says he's wearing vintage Zegna. Dude, everything is vintage now.
Monroe interrupts all the childish squabbling and tells Neville that Randall deserves respect because he's important to the republic. He instructs Neville not to make him regret sending him on this crucial mission.
Julia Neville chases her husband down the stairs and frets about where he's going and when he'll be back and whether he's in danger, and how she can't pretend any longer that Jason is dead. Man, Kim Raver's nose freaks me out. It points up too much. She tells her husband she's sacrificed too much for Tom and his job. She's looking at everyone, thinking she might see Jason. He reminds her that Monroe will have them both executed if he finds out Jason went AWOL.
Meanwhile, somewhere in Delmarva, Charlie is practicing her sword fighting. The drill ends with a blade at her neck, so Miles chastises her poor form and tells her to do it again.
Aaron flips through Rachel's notebook, utterly bewildered. He stares at one drawing of a little blobby thing with appendages and asks, "This is what caused the blackout?" She tells him there are bajillions of these devices in the world, each one the size of a virus, in the air, on buildings, even in people's bodies, and they're programmed to absorb electricity and replicate. Aaron's mind is blown--he asks if these organisms started reproducing uncontrollably, and she confirms that something went wrong in the Tower. He wants to go there and reprogram the things, disable them, but Rachel says it won't work; they'll just die, and this time she's resolved not to leave her lousy brat of a daughter behind.
