Title card with strange, saxophone-heavy bebop theme music. The dispatcher tells all units to be on the look out for a Hispanic man in a cape and no pants.
In the 2nd Precinct's locker room, Walsh asks two guys to leave, grabs a pair of bolt cutters and pops the lock on a locker. Shraeger asks when they're going to see the crime scene, and Walsh says his partner just died, and she's wearing a thong and probably won't last long, so she should be quiet. She says she worked Vice and closed cases, but is impressed with the thong thing. The locker is Kowalski's -- Walsh says that all of this stuff would get sent to Kowalski's wife tomorrow as he pulls out a pair of furry handcuffs, some porn, a leather mask, some rolls of money and what looks like two big bags of cocaine and shoves it all in a bag. He says she'll hear a lot of bad stuff about Kowalski -- that he punched a priest, choked out suspects -- but he got stuff done. She changes into some women's clothes Walsh pulls out (ew?) and he asks what she would do if her old Vice partner got killed. ("He had eight fingers, they called him 'Reach.'") She says "Whatever it took." He says "Burn that," and I think he's talking about the bag of porn, handcuffs and coke. Make sure the area is well-ventilated first. She pulls her breast enhancers out of her bra, and he walks out of the room saying "Come on."
Already starting to get to me, the voice of Dispatch says that she is cranky and will not accept any lip or guff from anyone as Michael -- I mean, Harold Perrineau -- I mean Det. Leo Banks walks ("WALT!" Sorry.) into the squad room wearing a shirt, tie and bulletproof vest. He can't believe Kowalski is dead, and asks Det. Eric Delahoy (Adam Goldberg) if he's crying. He says he's not, but Banks thinks that it's because Kowalski owed him money. Delahoy tells him to take off the vest, and Perrineau says he feels better with it on. Oh, and Goldberg's doctor called. Goldberg crumples the message up. Pretty, Latina Det. Beaumont walks up and asks if Delahoy is crying. Delahoy is getting a little ticked off. As clean-cut Det. Cole asks everyone to come together in prayer for their fallen comrade, Sgt. Brown comes in and assigns Delahoy and Banks an attack on a councilman's daughter. Banks says he wants to work on Kowalski, and Brown says he wishes his son would stop wearing his mom's underwear. Basically, we all want things, so suck it up.
Shraeger and Walsh visit Kowalski's widow, who says there were hang-up calls, but she just assumed it was one of his "girls," which she apparently knew all about. Yeah, Kowalski wasn't perfect. Also, he was afraid of the dark, from a childhood trauma. Walsh didn't know that, which makes me wonder how long they were partners. Basically, the man had flaws, but he was good to her. Walsh hugs her. Across town, Walsh and Shraeger are at the door of an apartment, and it's answered by a woman in leopard-print underwear. Tramp: "You're not the pizza guy!" Walsh: "This isn't a porno." Zing! She's apparently the mistress, or one of them, and she says she hasn't seen Kowalski in 3 or 4 days. Walsh tells her not to go to the funeral, but she says she loved him. Walsh says his wife and kids will be there, and she's the mistress. He throws one of the rolls of money from Kowalski's locker on the table. The mistress says fine, and that Kowalski was a good guy. Walsh says, no he wasn't. He was a cop. And, apparently, all cops are cheating, priest-punching dicks.
