Two middle-aged blacks are arguing in the corridor outside the interrogation room in Pennsylvania State prison.

"Damn it, this guy was killed in Pennsylvania, including my men. I will never give it to you NIA!"

"Take it easy, Joel. According to the regulations, NIA has jurisdiction over this case..."

"Don't mention it to me. All I know is that the guy's brother brutally killed six innocent women, and then killed five of my men. Five people, my God, grom, one of them, I just attended his son's graduation ceremony... "

"I understand how you feel, old classmate, but rules are rules. Moreover, there is something strange about this case. When the suspect first committed a crime in Pennsylvania, there was clear evidence that the suspect was still in Michigan. "

"Well, even if there's a little doubt, what's the matter with the hairy boy in there? Is there no one in NIA? Is such a young boy sent to despise us? "

"Shh, damn old Joel, keep your voice down. The man inside is not small. He once received a personal interview from director William and made a great success in New York. It is said that many top secret cases have been solved. When he was young, he was specially promoted by director William as a group leader. His future is unlimited. "

……

At this time, in the interrogation room, Sharon reached out to pull out the monitoring plug, turned and sat down, looked at Sam in prison clothes, handcuffs and shackles, and couldn't help laughing: "what's the matter with your face?"

Sam twitched his cheeks a few times and didn't have a good airway: "what do you say?"

"Beaten? Normal. " Sharon said with a smile, "I heard that Dean killed five special police officers. Those police officers only beat you once. If it were me, I would shoot you from behind, and then slander you for running away."

Sam smiled bitterly: "but Dean didn't do the key. Dean and I were still in Michigan when the first murder happened and never came to Pennsylvania."

Sharon opened the folder, picked up a document and threw it in front of Sam: "but the fingerprints, DNA, witness testimony and even nearby surveillance videos found at the scene prove that the murderer is dean."

Sam didn't even look at the document. He lowered his voice and said, "the reason is very simple. A deformation monster disguised as Dean committed this series of murders."

"Deformation monster?" Sharon recalled what was recorded in John Winchester's sheepskin book, "a monster that can completely transform into you by obtaining your DNA, and can completely confuse the false with the true?"

Sam nodded, "yes, it's that disgusting thing. It's impossible to guard against as like as two peas.

Sharon frowned and said, "I remember your father clearly wrote that the number of such monsters is very rare. In order to avoid revealing their identity, they live a life of constantly changing their identity and living in other people's homes. What's the matter with this deformed monster? It makes so much noise? "

"Have a grudge against us." Sam said helplessly, "two years ago, Dean chased a deformation monster. That deformed monster has a different style of behavior and is especially bold. He likes to disguise as a male host on a business trip, torture the ignorant hostess and finally kill her. It can be said to be a abnormal monster. "

"Dean tracked him for more than a month and finally caught him. Unfortunately, there was an accident at the last minute. Although the monster was seriously injured, he managed to escape. "

"This time, the monster deliberately pretended to be Dean and committed the murder in such a high profile. The purpose is to revenge and want to borrow our own hands to die Dean."

After listening to Sam, Sharon frowned and said, "by the way, where's dean? You've been caught. Where has he gone? "

"That's the trouble, Dean. He's missing." Sam frowned and said, "I've been looking for him secretly for three days, but I still haven't heard from him."

"True or false?" Sharon looked at Sam suspiciously. "You won't lie to me in order to protect Dean?"

Sam looked at Sharon suspiciously: "are you really Sharon?"

"I knew your boy would ask." Xie Lun was so happy that he reached out and pulled out a silver flashing knife. "The deformation monster is allergic to sterling silver products, isn't it? This is a silver knife. Do you think I'm afraid? "

Then Sharon brushed a fancy knife flower in front of Sam.

"Let me see if it's real sterling silver." Sam took the knife, looked over and over, and finally even took his teeth to bite. He nodded with satisfaction and said, "yes, it's pure silver."

Then Sam put the knife into his sleeve.

"..." Sharon said in silence, "Sam, you have changed. You have fallen. From a promising Ivy League college student, you have become as shameless as Dean."

Sam's face didn't change at all, as if he hadn't taken anything just now. He said calmly, "we came immediately after we learned of the murder in Pennsylvania. After some investigation, the trace of the deformation monster was found three days ago. But in the process of tracking, Dean disappeared. "

Xie Lun rubbed his chin and said thoughtfully, "listen to what you mean, you two seem to have been Yin by others."

Sam nodded. "Looking back now, it's really a little too easy for us to find the trace of that guy."

"If Dean falls into the hands of the deformer, it's... OK."

When Sam heard Sharon's words, he stared, "Why are you still cheering?"

"It's a very simple truth. Imagine if you catch your enemy, will you kill him with a knife or torture him slowly so that his life is better than death?" Sharon tapped his finger on the table and said, "what's more, if he killed Dean and the dead body was dug out, wouldn't he be exposed pretending to be Dean?"

"So I'm sure Dean is still alive, but I'm afraid he'll suffer some flesh and blood."

Sam was stunned. A moment later, he nodded, "yes, I didn't think of that."

He became nervous again. "Then we have to find Dean quickly. He can't tell what inhuman torture he is suffering now."

"How can I find it?" Xie Lun held out, "after the deformation, there are only two ways to distinguish. The first is to test with pure silver products. The second is its eyes, which will reflect light under the electronic screen. "

"But in the vast sea of people, the deformation monster may become anyone again. How should we find it? You can't compare the cameras of every family! "

Sam frowned: "we found a clue, but we didn't know if it was useful. We analyzed the location of the crime and found that the deformation monster was gradually approaching New York. The recent case occurred at the border between Pennsylvania and New York. "

Sharon's face changed slightly and said in a deep voice, "the sun thief is crazy. He dares to break into New York. Do you think the things he caused are not big enough?"

Before the voice fell, the door of the interrogation room was pushed open. Grom, senior inspector of NIA Pennsylvania branch, waved nervously to Sharon.

After Sharon walked out of the door, before the door was closed, grom said in a hurry: "just received a notice from the New York branch, Dean appeared in New York State and has killed a Patrolman!"
