John tries to chase her, but he's locked in the studio. Um, throw a chair through the giant window? He tries a few doors before trying to break the window, with no luck. He figures out the correct pitch he will need to play to shatter the glass, and then puts some liquid in a coffee mug to create the right pitch and amplify it. The window shatters. Meanwhile, out in the hallway, Randi is furiously punching the elevator button. Why not take the stairs? John runs into the hallway just as the elevator arrives, but it's full of furniture, so Randi takes off. John calls Frank on his cell phone while giving chase. He realizes that she climbed up the fire escape to the roof. John gets up there just in time to see Randi run in a door to the stairwell and lock it behind her. John runs to the edge of the roof, where he sees two pulleys and a wire attached to it. He looks down to see that the wire is attached to a couch on the ground. John yells down to ask what kind of couch it is, and then uses it as a counterweight to zip down to the ground. Hey, when he stepped off the wire, shouldn't the couch have come crashing down to the ground? He catches Randi just as she runs out the door.
Frank and John watch as Randi is escorted into the station. Frank says it's amazing what people will do for love. John asks if that's the way it usually turns out. Frank says it keeps him and his fellow cops in business. John wonders why anyone would fall in love. Frank says it sounds like Rachel trouble. He picks up a picture of his wife and says he doesn't regret loving her for one minute. He advises John not to worry about what could happen, and "focus on the now." I think John got a haircut between the last scene and this one.
Rachel reviews some notes in her apartment. Her bell rings. She walks out and finds a tray of red licorice. One long piece leads down the stairs. She follows it out and finds John holding the other end. I thought they were going to be all Lady and the Tramp and eat it from opposing ends, meeting in the middle, but then I remembered that he doesn't like red licorice. Rachel says she wasn't asking him to abandon his past. John says he doesn't know what he liked in the past, and he will always wonder, but he can "learn to love red licorice." Rachel says she can learn to love "Vienna sausage," which has got to be the worst last line of an episode ever. They kiss.
