But here's how it REALLY happened...

"I know who killed me!" Buzz declared, waving the list through the air.

"What's that in your hand?" Juliet asked, seeing the paper for the first time.

"The list of weapons and suspects…you know, from the game."

"Really?" Gus reached over and grabbed it out of his hand.

"Wait!" Buzz protested, trying to get it back. "I figured it out! I know who--"

But no one was listening to him anymore. Juliet and Gus quickly looked over the new clue while Henry and Lassiter just exchanged "What the hell are we even doing here?" looks from across the room.

"Well, it looks like Chief Vick is off the hook," Juliet sighed, pointing to the checkmark next to her name. "Whatever's not checked off by the end is the answer, right?"

"Of course it wasn't the Chief!" Buzz snorted. "She wouldn't murder me!"

"Thank you, Buzz." Karen smiled appreciatively.

He grinned back at her.

"I know it wasn't you." He gushed, his ears turning just slightly pink. "I figured it out! I-"

But before he could launch into his very first denouncement ever, he was once again cut-off by Juliet and Gus, who were on a roll of their own now.

"Wait…" Gus was saying, examining the list more closely. "…if you check off everything that's not the solution…"

"…Does that mean we check off everything we have in front of us?" Juliet finished the thought for him, suddenly breaking out into a wide grin. "Gus, you're a genius!"

"No!" Buzz almost shouted. "I'm a genius! I--"

"—That means that all the weapons we have in here are the ones that weren't used!" Gus concluded, taking a quick mental inventory and comparing it to the list in front of him. "Which means…it was the knife! The murder weapon was the knife! It's the only one we can't check off."

"It has to be!" Juliet agreed excitedly.

Buzz was nearly beside him as he tried desperately to get someone to listen to him.

"I know!" He howled. "I figured--"

Lassiter reached over him and grabbed the list out of Gus' hand.

"Give me that!" He snapped, then suddenly turned on Buzz. "McNab! You're the game expert! Why the hell didn't you tell me any of this?"

Now that all eyes were actually on him, Buzz froze like a deer in the headlights.

"I—" he stammered.

"Never mind." Lassiter rolled his eyes, turning his attention back to the list. "If the murder weapon is that easy to figure out, the murderer must be, too. All we have to do is figure out which of these stupid names isn't someone here….if the Chief gets a check next to her name, we must all get checks…"

"That part's easy." Gus spoke up. "Peacock. No one was Peacock."

"Then, that's our killer." Lassiter said firmly, handing the list back to Gus. "Case closed."

"But how is that possible?" Juliet asked. "How could someone who doesn't exist be the killer? Isn't it supposed to be one of us?"

Everyone looked at each other, completely baffled by this brand new quandary.

"I don't know," Lassiter muttered. "But Peacock, whoever the hell that is, is the killer. It's the only possible answer."

He snatched the list out of Gus' hand one more time, reading the names over with a sneer.

"Who the hell came up with these names, anyway?" He demanded. "Mustard? What kind of name is that? And Peacock? I hate peacocks. Damn annoying birds never shut up."

"And they strut around like they own everything," Gus agreed. "They think they're so great, just because they have those feathers…"

Suddenly, he and Lassiter looked at each other, their eyes wide as they were struck by the same thought.

"You!" They snapped, whirling around at the same time and pointing accusing fingers at Shawn, who was standing silently by the fireplace, watching the scene unfold in amusement.

"Me what?" He blinked innocently.

"You did it!" Lassiter said. "You're Peacock!"

Shawn gasped, absolutely horrified.

"Me? How do you figure that?"

"You never shut up!" Lassiter insisted.

"And you strut around like you own everything!" Gus added. "And you do think a lot of your hair…"

Shawn looked hurt.

"Gus," he clucked, shaking his head. "First of all, my hair is awesome. And, secondly…if you're still looking for that knife, it's in my back."

Gus rolled his eyes.

"But it makes sense, Shawn! You gave us all names that had some kind of meaning, but you never told us what your name in this little game was!"

"That's right!" Lassiter suddenly realized. "You said you gave Chief Vick her name because it was the only one left. Which means you must have given Peacock to someone else…but there is no one else, Spencer. No one else but you! You're the killer!"

He grinned from ear-to-ear, for once in his life having Shawn beat cold.

"I always knew I'd nail you for something, Spencer."

"It was you?" Buzz gasped, looking at Shawn with wide, wounded eyes. "You killed me?"

Shawn grinned evilly, his eyebrows arching, but didn't admit to anything.

He didn't have to.

Buzz marched resolutely over to the chalk outline of his body and picked up the BE BACK IN FIVE MINUTES sign.

"In that case," he stated firmly, handing the sign back to Shawn. "I'm definitely taking ten minutes this time."
