Last Night Gus
S6 episode 2 Aired on October 19, 2011

The whole SBPD crew is at a local bar celebrating the retirement of a fellow officer. Shawn makes a toast to Jim Dubois, the retiree, then calls for a round of shots. Juliet heads out early, leaving Shawn and the boys alone for a night out drinking.

Cut to the next morning at the Psych Office. We see Shawn and Gus passed out. They finally awake and have absolutely no idea what happened the night before. They are clueless as to why Shawn is wearing a shower cap, a gold chain and sandals that are not his, why Lassiter is there with a black eye and why Woody is also there &ndash both not remembering anything about the night before! There is strange debris everywhere, seemingly all clues to what happened last night.

Shawn tries to recall visions from last night, but every image is distorted. They search the room for clues and discover Lassiter's gun is missing three bullets, his car keys are missing, there is a huge dent in the blueberry, and there is cell phone video footage from the night before. They watch the video and see they were very chummy with a Hawaiian Shirted Man.

Just then, Woody gets a call from his office. They all head to the morgue where they are mortified to discover that the same Hawaiian Shirted Man is now dead on the slab, shot exactly 3 times &ndash which immediately leads us to believe that Lassiter's gun could have been the murder weapon. Shawn then realizes that the sandals he is wearing belong to the dead guy. Then, they realize that Gus and the dead guy had accidentally swapped phones and that they had his phone the whole time.

Concerned, Juliet pulls Shawn aside and asks him about the "strange, game-changing" phone call he made to her last night. Shawn doesn't remember it one bit, and Juliet needs to leave before she can get into any details.

Lassiter, Shawn, Gus and Woody all determine that they must have been drugged, as they remember none of this. Woody gives a drug test to all of them and confirms it... but who drugged them and why? The guys find more clues on the dead guy's phone: numerous pictures of a woman. Since they remember absolutely nothing from the night before, they head back to the bar they were at to get some answers.

Shawn theorizes that they may have been the unintended recipients of a round of drugged drinks from a guy sitting at the bar. But the bartender squelches that theory the second he reveals that the man Shawn thinks drugged them, is his partner, as in, his lover.

Just then, a super hot woman enters the bar, walks over to Gus and kisses him. Gus thinks this is some girl he hooked up with from the night before. The Hot Woman tries to get Gus to go with her, but Gus reluctantly stays to finish the investigation. Just as the hot woman is giving Gus her number, Shawn remembers a few clues from the Psych Office that lead him to believe they went to Bobo's Donuts after they left the bar.
