The greatest SouthLAnd writers have distinctive styles and voices.

This week’s writer, Heather Zuhlke, excels at texture; the connective tissue between characters, between scenes, between themes. She can give you all you need to know about a person, a relationship, a situation, with just a few careful words and moments.

That skill with texture was key to Heat, as this episode was all about interactions; the webs that link one person to another, and how those bonds hold up when the heat, the pressure, is cranked all the way up. Those brief, fragmentary moments were even more important than usual in a show that thrives on an aggressively existential insistence on the importance of the present moment, and the irrelevance of the past and the future.

Whether it was Cooper and the girl who brought him muffins, or Cooper and Steele, or Cooper and the veteran, or Sherman, continuing his alienating trend of being a total dick to everyone except the people who would actually deserve it, or Bryant, desperate to connect with his own son, and instead connecting with the dying son of a gangster via a toy Lego cop — each situation was short, brutal, and revelatory, thanks to Zuhlke’s absolute mastery of character through action. It sounds obvious, since that is the goal of TV drama (of all drama, all writing) — but it’s not. It’s hard to get right even some of the time — Zuhlke nailed every single beat from start to finish.

The acting in this episode was exemplary. As you can tell from the list above, Cudlitz had a lot to do, and he did it brilliantly. Ben McKenzie is fearless this season, utterly willing to throw off Sherman’s idealistic former self in favor of his transition to a hardened, jaded douchebag. Hatosy is great as always, keeping Bryant’s combustibility in check, but only just. He effortlessly conveys the fact that Bryant has much more experience, and is likely a much better cop, than Sherman.

I haven’t mentioned Regina King yet, because she deserves special focus for this episode, which was really all about Lydia’s much welcome return to being an awesomely powerful powerhouse of a woman. From the opening flashback when we see her start to kick the ass of a kickboxer in a street brawl, to her first shot doing insane pushups, through her beautifully depicted banter with Dorian Missick, King owned this episode. She’s a natural match for Zuhlke’s style, able to convey extraordinary amounts of emotional information with the barest of words or gestures. Her joy at her comeback made the ending all the more devastating.

A quick word about that. SouthLAnd excels at dropping you into unknown trouble and making you feel it, instantaneously — the moment contains all you need to know for it to f**k you up emotionally. Earlier in the episode, the show made a rare minor misstep with Mendoza’s story. It could have been the character being too new and unfamiliar, it could have been that we don’t connect with Sherman’s loyalty to him, or it could just be the precise sleaziness of the performance. Whatever the reason, there were only two moments in the arc that truly worked: Sammy gaving the Lego cop to the dying kid (at which point it started raining on my face for some reason), and the very end of the arc, when Sherman is left alone in the hospital corridor — utter isolation that definitely hit home. Those moments aside, that story just didn’t have the emotional power to jump start our feelings.

The same cannot be said for the ending, which was horribly savage in the quietest of ways. Classic SouthLAnd. We didn’t even know what was truly happening. We didn’t need to. Regina King’s heartbreak was backed up by everything that had happened to her earlier arriving in that scene like an emotional freight train — that’s brilliant writing. The moment was flawlessly conveyed, and the previous 40 minutes slammed into you while you were down. King is an extraordinary actress, and why she doesn’t have a truckload of Emmys at this point is beyond me.

The texture that was key to this week’s script was also there in Dana Gonzales’s lighting. While Jimmy Muro is the undisputed master of capturing that Los Angeles light, Gonzales has been quietly excelling in a number of SouthLAnd episodes (most notably, God’s Work). He can harness extraordinary early morning golden hazes (he shot the golf course like an alien planet shrouded in sentient light), and he can wrestle lens flares out of literally any shot — the patrol officer’s badge when Lydia and Ruben walked up the hill to their first case, or the patrol car lights on a cloudy day after Cooper was shot at. Gonzales is a legendary DP.

Heat continued the season five trend of being tighter, more compact. Sometimes, that constricted the emotional responses a little; mostly, it accentuated them. It’s simply the rawest, most real show on TV right now. Challenging, uncompromising, and brilliant.
