Shawn Spencer watched as his favorite person to annoy, Carlton Lassiter, scowled deeper than Shawn had ever seen, which was odd because Lassiter had not even noticed Shawn yet.

"Right, we're on our way," Lassiter said, then he hung up.

"O'Hara! Let's go!" He called to his partner impatiently.

"I'm coming too!" Shawn yelled.

Lassiter glared, but, for once, he did not object.

"So Lassy," Shawn said once they were in Lassiter's car on their way to the crime scene. "What is it about this case that's got you so upset?"

"I don't know what you're talking about Spencer," Lassiter said.

"I think you do," Shawn argued.

"I am not upset," Lassiter growled.

"Which is why you have a death grip on the steering wheel?" Shawn speculated.

"Shawn," Juliet warned.

"The reason I have a "death grip" on the steering wheel, Spencer, is because I am restraining myself from shooting you," Lassiter said.

They arrived at the scene with Lassiter no less mad and Shawn with no more answers. There was an attractive woman shot dead in her kitchen and food splattered on the floor from what she had been cooking. Lassiter glanced at the woman before asking Buzz what had happened.

"You know her," Shawn hissed in Lassiter's ear.

Lassiter turned to glare at him.

"How did you know her?" Shawn asked.

"Shut up Spencer," Lassiter warned.

"Aww come on Lassy-face, you can trust me," Shawn taunted.

"Shut up Spencer!" Lassiter repeated.

"What? Was she like a one-night-stand or something?" Shawn continued.

Lassiter grabbed the front of Shawn's shirt and pushed him into the wall.

"Don't you dare even suggest such a thing," Lassiter said through clenched teeth.

"I loved her."

Shawn froze, as did Juliet and Buzz, who had heard him.

"You loved her?" Shawn asked, making sure he had heard right.

"You bet your ass I did," Lassiter replied, releasing Shawn's shirt.

"So what's her name?" Shawn asked.

"You wouldn't believe me if I told you," Lassiter said.

"How do you know?" Shawn said doubtfully.

"You didn't believe she existed when I first mentioned her," Lassiter replied.

Shawn was confused, "So...what's her name?"

Lassiter looked at Shawn, almost sadly.

"Polly Smith."
