Olivia and Astrid come out of the office having settled on a suspect. Brian Dempsey, Luke's dad. He was fired by Greg's dad, and apparently threw a fit over it. And his wife recently remarried the Chicago day trader after a really nasty divorce from Brian. Peter asks about a connection to the car salesman. "Uh, we're still looking for that connection, but it looks like Dempsey's MO is to hurt people who screwed him over by going after their loved ones." Olivia calls Charlie, to tell him to get over to Brian Dempsey's house, because that's their guy.
The sun sets over Boston Federal Building, and Sanford Harass strolls into a room where the agents are looking through one-way glass at Luke Dempsey sitting in an interview room. Harass asks where the suspect is, and Olivia says there was no sign of the guy, so they picked Luke up at work. Harass asks for the plan. "We're waiting for the right moment," says Charlie, whatever that's supposed to mean, other than provoking an argument between Harass and Olivia. Harass figures they should just go in and "break him" and Olivia doesn't: "I think that Luke suspects there's something wrong with his father. If we go in heavy-handed, then he could shut down, or call a lawyer, and then he won't tell us anything." Harass tells her it's her job to make sure that doesn't happen, which is kind of what she's DOING, asshole. She snaps that she's "more than familiar with passive coercion," and Harass is all, "Good! Then put your little hands around his neck and squeeze. That's an order."
Harass leaves to go be a douchebag somewhere else, and Olivia and Charlie walk into the interview room. Olivia asks Luke where his father is, and Luke says he has no idea. She sits down and asks Luke to tell them about him, and Charlie figures Luke's dad has gotten a rough ride, what with being fired, dumped by Luke's mom. Charlie doesn't mention the baldness, but yeah. The baldness. "People don't understand him. They don't take the time," says Luke. Olivia asks when he saw his dad last, and Luke, obviously lying, says it was a few weeks ago.
