It’s the home of Ken Olson, a copycat murderer.
After dark, Dexter breaks into Olson’s house through a window. Inside, it’s dark and cluttered. Using a flashlight, Dexter searches through Olson’s desk, finding magazines about firearms and two handguns. As he shines his light around, he finds a wall covered with clippings about the Bay Harbor Butcher. Looks like I have a fan club, membership of one, Dexter thought.
Unexpectedly, Olson arrives home. When he flips a light on, he notices a desk drawer open and a window ajar. Suddenly, Dexter grabs Olson in a rear choke hold and doesn’t let go.
Dexter: Why you so interested in the Butcher?”
Olson: “Who the fuck are you? Holy shit, you're him, aren't you? Stop. Stop. Don't kill me. Don't kill me. I'm like you. I take out criminals.”
Dexter: “You mean you try... pitifully.”
Olson: “No, that was just the last one. He got away. I should have never made it personal.”
Dexter: “You've killed others?”
Olson: “That's what I'm trying to tell you. First was a drug dealer -- I ran him down with my car. It felt -- it felt fucking great, even better than the free stash I got off him. And then this guy at work found out I was fucking his wife. He started to beat on her, so I pushed him down a stairwell. The cops thought it was an accident, but it was me." [chuckles] "See, you can't kill me.”
Dexter: “I wasn't going to... until now.”
He chokes Olson until he passes out and then takes him to the railroad car where he attempted to kill John Henry. Dexter dismembers Olson with a cleaver and leaves his remains to be found by police so that other copycats will be discouraged.
