Miles says they can't call the police, or put the man in jail, and over Monroe's protests, he shoots the big man's friend, then the big man. I gotta, say, everyone on this show is very good at killing people with one shot to the chest. Didn't we learn from the Lost pilot that that isn't always effective? Monroe can't believe what Miles just did, and asks him if he plans to walk around killing people now. Miles says somebody has to do something, or there won't be a civilization left. He bends to the man on the ground -- and it's Jeremy. They help Jeremy up and walk away.
Present day. Miles asks Charlie to tell him what she's brooding about back there. He says he wants to hear her tell him what a monster she thinks he is. He tells her she doesn't understand, and she says that he did manage to save all the rebels back at Hannigan's, so part of him must still care about others. Well, yeah. He seems to have founded the militia with good intentions, to protect the weak, at least. He tells her she's wrong.
Grace's house. Aaron tells Maggie a story about a kid who used to beat him up in the fifth grade. "Kid was the Mozart of wedgies." Aaron gets all the good lines. Aaron says he grew up, and it got better: he got three hundred employees and four homes and a terrific wife, but the punch line was the blackout. The world went back to being the schoolyard where the bullies are in charge. Man, that is a terrible joke.
Over on a table, the MacGuffin chirps. Aaron grabs it, and it's lit up. He looks at the Discman on a table by the window, which has just switched on as well. He picks up the headphones and "I Heard It Through the Grapevine" is playing. I think I'd start crying if I hadn't heard Marvin Gaye in fifteen years. Maggie's iPhone turns on and there's the picture of her kids and how she doesn't burst into tears I don't know. (We decided a few days ago that Maggie must have been on vacation in the States when the blackout happened, because otherwise she'd have actual hard-copy photos of her kids. Even in this electronic age, everyone still has real pictures. I have like forty pictures of my nephew just on my fridge.) Then the music stops, the phone blinks off. "How?" she asks. Aaron doesn't know. But let's never leave this magical electronic house!
Next time: Aaron says they can't tell Charlie and Miles about the MacGuffin. Someone has been following them, someone's gonna die, and someone FINALLY duct-tapes Charlie's big mouth shut.
