Buy More. Jeff tells Lester they need to talk, but Lester says it's not necessary. He gets that they're no longer friends. "Like I care." Jeff says he cares, and Lester needs to learn there are repercussions for his actions, which is why he called the cops, who are there to arrest them. Lester asks what for, and the cops say, "Attempted homicide." Lester screams for Jeff, but Jeff doesn't flinch. The cops cuff him and lead him away.

In the apartment courtyard, Alex stands up for herself and tells Morgan they're not going to get back together. He lied to her -- he told her was done spying, for one thing -- and hurt her. He's her hero now, but not her boyfriend. She says they can still be friends, and he says he understands. They hug. I don't care about this relationship enough to quibble or anything, but that was rather anticlimactic. Though I'm glad she didn't take him back. Anyway, they arrive at Sarah and Chuck's, and head in. Alex asks if her dad's there yet, but Sarah says he'll be a little late.

Cut to Casey, dressed all in black as he's listening in on a conversation between Decker and the Viper, who's less than a block away (lucky for him she does this in an alley by Skyping on a tablet). I'm not 100 percent sure what it's all about, so I'll recap it verbatim:

Decker: "You haven't said anything yet that's made me think you're still the man for the job." (What job?!)
The Viper: "I have a reputation to repair. This will get done." (What will get done?!) "You need to understand, however, that I have to protect my cover."
Decker: "Obviously. Which means..."
The Viper: "Neutralizing everyone who knows who I am: Walker. Grimes. Casey. Bartowski. Casey's daughter." (So, if she's doing a job for Decker, but wants to neutralize all of these folks first, the job obviously doesn't have anything to do with any of these people, right? Because that wouldn't make any sense at all, and this show's final-season wrap-up better make some freaking sense.)
Decker: "You have approval on everyone but Bartowski and Walker. Now get it done."

One of the Viper's guys sees Casey, and puts a gun to his head. But Casey kills him with a gunshot. The Viper and her gang hear this, and head over. She tells him his life is over, and pulls a gun. But he shoots them all (and there are at least six), leaving them all dead in the alley.
