Vic and Monica team up to undermine Antwon's deal with the DEA. And the tenacious Vic delivers, giving Monica the pleasure of slapping Mitchell behind bars again. Danny and Julien continue to re-bond. And Dutch and Claudette do the same, as Dutch is surprisingly offered the now-vacant Captain position, and turns it down in solidarity with Wyms.
The Team look like their old selves again, joking around with each other and looking out for each other. But storm clouds are on the horizon, as I.A.D. investigates Lem over the unreported seizure of heroin from Pitarro. And Monica runs up against her old foe at Child Protective Services when she discovers that a kid from the troubled foster home featured in an earlier episode is selling drugs and makes a fateful decision to seize the house, even though the seizure program is supposed to be shelved. This results in her firing, and several heartbreaking scenes as she says goodbye to Vic and the Barn.
The final scene shows the entire Barn gang in a bar, living it up. It just didn't ring true to me- it's just not The Shield's style. Still, I can't wait until Season 5.
