They arrive at Bobo's Donuts and discover they had been there last night questioning the Shop owner about the woman in the photos. It turns out their Hawaiian Shirted friend was hired to find the woman in the pictures because she was suspected of cheating. They take a look at the security camera footage from Bobo's: a Man punches Lassiter in the face, and the dispelled bullets from Lassiter's gun were used to shoot at the giant Bobo's Donuts statue that fell on the Blueberry, causing it to be crushed.
Just then, Lassiter gets a call: another dead body. The body belongs to the same man who punched Lassiter in the security footage! Shawn figures it out that Scott and the Hawaiian Shirted P.I. knew each other and were in contact because the P.I. had Williams' number in his "recently dialed" call history.
Our guys and the SBPD are now at Williams' home investigating the murder. Shawn realizes from a photo in the house that the pictures of the woman the P.I. had on his phone are of the same woman who lives there. In fact, she is Scott's wife. They then determine that the P.I. was hired by Scott to investigate his cheating wife. Now, they think it was the wife that killed both of them.
Just then, Shawn gets a worried call from Henry who is at a motel room and has no idea how he got there and why. From this, Shawn puts it together that they must have went to this same motel last night thinking the wife was going to show up there. They get confirmation of this by checking out her vacated room. But the room is rigged to blow up via gas leak, so the guys quickly escape by jumping off the balcony and into the unkempt pool.
Back at the SBPD, while Vick is lecturing everyone about their recent behavior, the real Ed Lover shows up to retrieve his gold chain that Shawn apparently stole off of him at a club the night before. Just then, Gus gets a call from the hot woman. Having had enough of all this, he leaves to meet up with the hot woman.
Next, they all analyze the photos from the P.I.'s phone. Shawn takes a closer look at a picture and recognizes the face of a man the wife is eating lunch with. From there, Shawn gets SBPD's tech guy to alter the face in the picture to look like the mug shot of a man on the Most Wanted List – a man named Leroy Jenkins, who looks just like the man the wife is eating lunch with in the picture. After a few adjustments to the photo, Shawn's theory is proven right. Leroy had been keeping a low profile for years, and when he found out he was being followed by a P.I., he had both Scott and the P.I. killed. Then they all realize that Leroy wasn't working alone, and that his partner was Leroy's next of kin, Lilly Jenkins. She is the same girl who approached Gus and kissed him at the bar. She was actually at the bar that night tracking the P.I. to get his phone to wipe any evidence he may have recorded of her dad Leroy Jenkins. But when she saw there were cops, she drugged them to make sure they wouldn't remember any of the events surrounding Leroy's whereabouts. And Shawn puts it together quickly that Lilly is the same Hot Chick that was all over Gus, and that she was only after Gus to get the P.I.'s phone, which is also the same phone Gus still has in his possession.
SBPD immediately heads over to Gus's apartment to save him from being killed by Lilly. When they arrive, Lilly has already drugged Gus, and Leroy is there with a gun pointed on a woozy Gus. Lassiter and Juliet show up just in time, take down Leroy and arrest him once and for all.
We end with Shawn and Juliet discussing the fact that Shawn, in his drugged state from the night before, called Juliet suggesting they move in together. Surprisingly, in the end, Shawn is the one who suggests that they actually do move in together. However, Shawn is shocked when Juliet tells him she isn't quite ready to make that next step.
