Ben Sherman finally gets to drive his own patrol car when mentor Cooper acts instead as partner for a female colleague, whose shocking incompetence he demonstrates and scolds mercilessly. Ben is shocked but powerless when he sees a bully father 'punish' his gentle son for being a 'sissy victim' of street rabble by imposing front garden chores in female underwear. Ben smartly questions a Korean couple and their young son Matthew whose sister is missing and learns enough to find her. Cordero told Lydia not to be allover recovering Russell, but she only believes it when his cold reception and other visitor make it obvious. Written by KGF Vissers
'U-Boat' is "Southland"'s best to date, and not at all easy to watch. Partially for the way Chickie's been handled. She's suddenly the squad pariah because of not turning Dewey in years earlier, but because her cop skills have been on the decline. I have a problem with this because it feels contrived, something shoved in without any prior foundation-laying, although it flows well with the rest of the episode.
This is ultimately about two officers finding out who they are. For Chickie, it's a tall mountain because she's ostracized. For Sherman - who graduates to his own patrol unit - it's a different challenge. He's this show's closest thing to a boy scout, reckless but incredibly big-hearted. His day consists of dealing with an emotionally abusive parent, locating a lost child and answering the pleas of a woman who's being stalked. He finds the child unharmed - which is just the win we need because the other calls yield bitter losses.
To me, this is where the show excels: focused on a couple of character relationships and showing what it means to be out there on the streets. A huge part of that is knowing you can't save everyone, and that turns out to be a painful lesson.
