If Gus had learned only one thing over the many years he had known Shawn Spencer, it was that Shawn was unreliable. And yet, he still continued to expect things of his friend. Things like having his phone, flushing the toilet, locking doors, and being relatively on time. In this particular instance, Shawn had caused some sort of discrepancy in the Psych financial records, and so Gus was forced to call his associate in on this Friday night to try to sort this mess out. Gus sat as his desk looking at the clock, drumming his fingers impatiently. It had been nearly two hours since he had spoken to Shawn. Miraculously, Shawn had answered his cell phone. When Gus offered to pick him up to bring him to the office, he had said that he would get there on his own and was leaving right away. So where was he now? It was after 11 o'clock, and Gus had much better things to be doing than waiting for Shawn.
He was just beginning to nod off when he heard a car pull up in front of the office. He hopped out of his chair and snuck to the window to find out what the hell Shawn's reason was for keeping him waiting so long. He could just barely make out under the light of the street lamp Shawn sitting in the passenger seat of the car and Detective Lassiter behind the wheel. Wait – what? Lassiter? Gus did a double-take. It was definitely Lassiter's car, but it just didn't make any sense. What the hell is Lassiter doing driving Shawn around? What kind of trouble did Shawn get himself into this time?
As Gus was running through what Shawn's possible antics could have been, he found himself observing a scene that he simply could not believe. Shawn reached across the center of the car and set his hand at the back of Lassiter's neck. The detective turned to be able to touch Shawn's waist. They leaned towards each other and met in a long kiss.
"What?" Gus uttered aloud in shock. He scrambled back to his desk chair, trying to look normal, as if he had been there the whole time, which he wished were the case. He tried to scour the image from his mind as he waited for Shawn to come inside. He jumped when the door latch clicked to indicate his friend's entrance.
"What's up, man?" Shawn called out as he tossed his jacket over the doorknob. He turned around to find Gus glaring at him from over his computer screen. "Wha'd I do?"
"You were supposed to be here two hours ago, Shawn," Gus said stiffly.
"Was I?" Shawn plopped down into his own chair opposite Gus and set his feet up on the desk. "Why am I here anyways?"
"Cause we got something screwy going on with the books and I need to figure out what you did. We've got almost two-hundred and fifty dollars missing and unaccounted for as of last week. What did you do?"
"Oh, that," Shawn acknowledged with a smirk. " I bought some stuff for the office."
"What kind of 'stuff'?"
"Christmas decorations."
"You bought two-hundred and fifty dollars worth of Christmas decorations?" Gus was incredulous. "Well… where are they now then?"
"Oh, you'll see soon enough. Well, I'm getting pretty bored of this, Gus. Can you bring me home now?"
"You are ridiculous, Shawn." He paused. "Fine."
