Okay, so it would seem that I have found a pairing I ship that either no one else does, or no one has had the inspiration to write about. Keep in mind that I have only seen the first and second seasons of Psych. Don't knock it until you have thought about it.
Detective Carlton Lassiter would always say it had begun when the psycho psychic Shawn Spencer had turned up. The detective had been sure, so sure, that he was willing to bet his badge that the nuisance had been the perp they needed to arrest. But, that damned Spencer had managed to convince everyone of his abilities. Carlton was no fool. He saw the truth. That is why when Spencer had the gall to corner him after that first case, the detective had had none of it.
"Lassie-face! Watcha running off to do?"
"Nothing, Spencer. Leave me alone."
"Aww... I know you're upset about that lady-friend partner of yours leaving, but you know-"
At that point Lassiter threw Spencer into the wall right outside the door to the precinct. The man's lined face was inches from the psychic's.
"I said, 'Leave me alone.'"
The older man pulled off and walked away, but the younger remained locked in position. Watching the salt-and-pepper haired man's back, the sleuth made a series of deductions that would have even made the spirits impressed.
1- Carlton Lassiter had broken off the relationship with his old partner.
2- Carlton Lassiter was in love with-or at least had a crush on-someone on the force.
3- Carlton Lassiter had no idea.
Shawn decided that he had just found a new case. No matter how long it took, he would find out who it was. The pseudo psychic's face lit up in a smile. This was going to be very fun.
