Juliet walks into the Psych office to find Shawn and Gus talking to the two FBI agents that had come in to the station earlier. They explain their plan to her but will she believe them? Or will she arrest the brothers and take them in?

The room got dead silent, nobody spoke a word, nobody moved, nobody even breathed. Then there was a soft gasp for air behind Sam and Dean. Then the sound of quick footsteps.

The boys quickly turned around and they saw her standing in the doorway with a look of horror on her face.

Shawn looked up and said one name.

"Juliet."

Juliet stood there for a moment, her mouth hanging open in utter shock as she took in the scene before her. Those two fake FBI agents that had come into the station the other day were here, in the Psych office. Juliet had no idea why they were here but she was not happy with their presence.

Pulling out her gun, Juliet pointed it at the two unfamiliar men, scowling deeply at them. "I don't know who the heck you two are but you're both insane and I'm gonna have to take you in," Juliet announced. The men raised their hands in a signal of surrender, not wanting to provoke her.

"Hey, we're friends. Shawn and Gus know us," the shorter one said. The taller one nodded, his eyes wide and innocent like a puppy's.

"Jules, it's okay. We do know them," Shawn reassured her. "This is Dean and Sam Winchester. They're brothers." He pointed to them when he said their names and he could see Juliet relax ever so slightly.

"Yeah, we came to Shawn for some help on something we're dealing with," Dean told her. He then put his hands on his hips and smirked at her. "And might I say that I've always found it sexy when a woman can handle a gun."

Sam rolled his eyes and let out a frustrated groan before slapping his brother over the back of his head. Dean flinched and punched Sam in the arm, earning a glare from Shawn.

"Shut up, Dean," Shawn spat, anger boiling in his stomach at the Winchester's attempt at flirting with Juliet. Dean glanced at him in surprise, his green eyes wide.

Juliet watched this exchange suspiciously before slowly lowering her gun. "Alright. I trust you, Shawn," she said. She put her gun away but pointed at the two brothers, glaring at them.

"But if you two do anything stupid, I won't hesitate to shoot you," she growled. Shawn smirked and shared a proud look with Gus as the Winchesters nodded vigorously. Sam even gulped nervously at the threat.

Clearing his throat, Shawn gained the attention of everyone in the room. He then turned to look at Juliet. "Jules, the reason Sam and Dean are here is because of Lassie," he said. Juliet cocked an eyebrow in confusion.

"What? Why? What has Carlton done?" she asked, worried for her partner. "I remember what you told me, Shawn, but not a lot of it made sense."

At that statement, Dean crossed his arms and turned to look at Shawn. "You told her?!" he exclaimed. "You can't just go around telling people that monsters are real and that a trusted detective is actually a cold-blooded murderer!"

"Wait, what?! What are you talking about?! I mean, Carlton has killed people but never in cold-blood!" Juliet defended. This was all too much for her right now.

"Sorry to tell ya, sweetheart, but you're partner IS a murderer, at least in our world. His name is Cain," Dean explained. Juliet shook her head and crossed her arms over her chest.

"No, I don't believe this. I can't. Lassiter is NOT a murderer," she stated firmly. "Shawn, how am I supposed to believe this?"

Shawn sighed, feeling like the weight of the world was resting on his shoulders. Maybe it was. "I know how you feel, Jules, but it's the truth. I told you about the Mark of Cain and what it can do to a person. Lassie has it but we have a plan to get rid of it," Shawn assured her. Juliet looked at him with wide eyes. He could tell she was scared.

"Okay... So if all of this IS true, then how do we get rid of this Mark or whatever it is that he has?" Juliet asked.

Sam and Dean quickly started explaining, Shawn and Gus occasionally throwing in their own statements about their plan. Juliet's eyes got wider and wider as they did before they finally finished.

"So...let me get this straight; I'm supposed to lure Lassiter away from the station so you can perform this spell?" she confirmed. The brothers nodded.

"Yup. And he needs to be alone," Sam reminded her. Juliet nodded and gulped down the lump in her throat. She then let out tired sigh.

"Alright, I'll do it. Let's just hope this plan of yours works."
