Jason Gedrick, who's likely been bored out of his skull throughout this scene but has been waiting patiently, dumps the gun Viktor used to kill Anderson on the table, and when Alex asks what he's supposed to do with it, puts two fingers to his head and pantomimes pulling a trigger. Well, the man knows how to make himself understood, I'll give him that. Isaak Pullo leans forward and suggests Alex look at his children's faces, as they would want him to do this for him. Alex, perhaps not quite convinced of the veracity of that, asks what happens if he doesn't, and Jason Gedrick's there with the answer: "We'll kill you anyway. And throw your wife and fucking kids in the river." I'm getting mixed signals on how romantically this decision should be treated. Isaak Pullo mildly chides Jason Gedrick for the vulgar threat, but essentially follows it up with "but the man makes a good point," and to drive it home, the silent henchman (while using a cloth; he really is compulsive about the prints) picks up a shot glass and pours Alex the last bit of vodka he'll ever taste, even patting him on the back sympathetically afterward.
Alex, not needing long to figure out there's only one path available to him, slugs back the booze, and Isaak Pullo assures him that it'll be quick, "like turning off a light." "Quick" isn't the same as "painless," you'll notice, but hey, I guess there's only so far even Isaak Pullo is willing to upsell this. Alex puts the gun in his mouth, but Isaak Pullo repositions it so he'll be shooting it into his temple, and while I think one would probably be as effective as the other, I appreciate his attention to detail. Alex, crying a little, says, "For my family," and Isaak Pullo nods with an appropriate amount of gravitas before Alex pulls the trigger. Isaak Pullo barely even blinks, much less flinches, which makes me wonder how many former employees' kids' educations he's currently paying for.
At the station, Dexter is working in his office when he spies Hannah entering. Their eyes meet, and after DVO gives us some unnecessary expository crap, she comes over, and after a bit of chitchat, lets us know that the Sheriff's Department found the body of one of Randall's victims. Dexter confirms that, saying they went back one last time and expanded their perimeter, and Hannah tells him that her lawyer "said it was for the best" that she cooperate in helping them find the rest of the victims. Not sure that makes tons of sense, but I suppose now that they know Randall was telling the truth, they're going to be redoubling their efforts to find the other two corpses. Anyway, that's probably irrelevant, as Hannah is also there for another reason - she heard that Dexter was the last person to talk to Randall before his death. Answering her unspoken question, he informs her that Randall's last words were about her. Hannah's reaction to that is decidedly mixed, and she tells Dexter that it was too painful to stay in contact with Randall after they were both sentenced to their respective punishments.
