Elsewhere, Big Jim is out on the water in a boat, presumably heading to Bird Island…
…and Junior is driving around looking for people to harass. He gets his wish when someone walking along starts high-stepping it when he sees Junior’s car. He eventually chases him down, throws him on the hood of his car and finds out that he shoplifted a canister of salt from the convenience store. Junior’s puzzled about it, so the thief happily explains: "You kiddin'? Better than cash if you want to get into the cement factory."
The cement factory is where Maxine and Barbie pull up, as Maxine warns him about collaborating with Big Jim since you can’t trust him. Barbie’s all, like I can trust you? And Maxine looks genuinely offended as she says she’s never lied to him.
They get out of the car -- Max’s door is opened by some thug -- and the cement factory is goddamn busier than Hamsterdam in The Wire all of a sudden, because Maxine is offering "adult entertainment," and she takes offense to the "brothel" part of Barbie’s sneer that she’s offering her "usual booze, cards, brothels," and she snaps that she doesn’t deal in prostitution. (Which kinda makes Barbie’s use of the word "usual" strange, but it’s also weird that he’d act all superior to Maxine’s dealings, considering how he works for her collecting her money.)
Anyway, inside, we see this black market that deals in… salt? I guess? With some bare-knuckle Fight Club action going on. "Welcome to my brave new world," Maxine tells an uncomfortable Barbie, as he looks around at this implausible scene that has sprung up in, like, a day. Seriously, now that Breaking Bad is back, Dean Norris’s surroundings here are suffering from conspicuous comparison.
Speaking of Hank, Big Jim arrives on Bird Island and docks at the pier for the absolute mansion powered by a couple of generators. Is this the same lake contaminated with methane? And there's just this giant house on it undisturbed by the looting and rioting, despite being well within the parameters of the dome and easily accessible by boat? Could the writers maybe have made a map of what actually is under the dome and work within those parameters rather than just pulling shit out of the air whenever necessary? He makes sure his gun is easily accessible and starts walking the grounds, where he finds Mare Winningham tending to some plants. She recognizes him from his car commercials, which she likes, because he doesn’t "scream from the TV like the rest of them." She happily introduces herself as "Agatha," the caretaker for the place. Not for any Maxine, but for Oliver Loughlin, who’s on the other side of the island, tending to his boat. He explains about being a councilman and says he’s checking up on residents in this time of crisis. She admits to being relieved to be here in the peace and quiet. Let’s go inside for some tea, shall we?
