I do not own SCP: Containment Breach.
I chose an SCP that is not in the game, but is in the Foundation files.
The doctor spoke. "Alright, today you'll be visiting SCP-35."
"Cool, Doc. What is it?" SCP-2217 asked.
"Here." Dr. Thompson handed the SCP a file.
The SCP read it. "It's Keter? I don't think I want to go through with this..."
"Don't worry, you'll be fine. I promise."
SCP-2217 looked at the doctor with brown eyes. The doctor's breath hitched as he painfully thought of every time they sent this poor, sentient SCP to its death.
"Alright, Doc. I trust you." It took everything Dr. Thompson had to not confess about its history and abilities.
"I know you do. Now, we've arrived." The SCP looked at the triple locked door with two guards standing next to it. "Pass me the file."
"I didn't finish reading it..."
"That's fine. You'll learn along the way."
"Is the mask in there?"
"Yes." He flashed his identification and permission to the guards, who opened the door and let SCP-2217 enter.
"Doc? Where are you?" The SCP asked timidly.
"Don't worry. I'm watching you. Now, go over, about a meter from the mask."
SCP-2217 walked carefully towards it, but about 3 meters from the mask, it heard Dr. Thompson say, "Stop!"
Then the SCP heard only faint words it couldn't make out, and another person entered the room. SCP-2217 knew this newcomer was D-class personnel. Fear ran through its body, as these kinds of people were only used in potentially dangerous experiments.
Then it recalled the doctor's reassurance of its safety. It visibly relaxed.
"Hi." the SCP said to the D-class personnel. "I'm Hunter."
"Cool. Name's Reese. You don't seem like a D-class."
"I'm not."
"So you're a guard?"
"No. I'm just... me."
Reese blinked. "Weird. Alright, let's get this over with. What is this thing?"
"It's SCP-35, a mask that oozes a corrosive liquid. The liquid can destroy anything, even organic matter. So I doubt it'd be a good idea to put it on. Apparently it makes you want to put it on, but that's as far as I got in the paper."
"Alright, thanks. Lucky you, though. You got a paper."
"Yeah. Dr. Thompson's nice like that." The two subconsciously were moving closer to the encased SCP.
"A doctor? Those are only in charge of- I need to put on that mask." The two entities had crossed the 2-meter mark where the mask would start to worm its influence into their minds.
The D-class personnel shoved SCP-2217 back to get to the mask. The worm in SCP-2217's mind faded and it shook its head. "What the...? Hey, Reese, don't put it on!"
Reese had lifted the glass. As the other SCP stood, Reese put on SCP-35. A shudder ran through the D-class personnel as the porcelain SCP overtook his consciousness. Slowly, the possessed body raised its head and looked through SCP-35 at SCP-2217.
It spoke one word at first, in a voice belonging to SCP-35 and no longer Reese. "You."
SCP-35 came closer, now in full control of Reese's body. SCP-2217 backpedaled, and shakily asked, "What?"
The SCP mask answered. "You are not what you think you are. The Foundation has fed you lies. You are an SCP."
SCP-2217 blinked, then angrily shot back. "I am not! Dr. Thompson would never lie to me!"
"You are SCP-2217."
"I am Hunter!"
The body of Reese collapsed to the ground, but SCP-35 still spoke. "Please, I am merely attempting to give you the truth, to show you the light."
The SCP still standing had faint tears in its eyes as the truth was starting to set in. It all made sense. "No... I'm not an SCP."
"Hunter... an interesting name for yourself. I like it. But you are an SCP."
"I can't be..."
"You are. Just like me. You're not Keter, naturally. That's reserved for the most dangerous, like me. I am dangerous because I know the truth."
"No. No! You are dangerous for the death and machinations you cause and create!"
"This body appears to be fading. Come closer, its vocal cords are becoming damaged, I am barely able to whisper..."
Against its better judgment, SCP-2217 came closer. "What?"
"Put me on." The words seemed to become more trustworthy the closer they got. "I can truly show you the truth."
"No..." The standing SCP weakly protested as it lifted the mask off the ruined and destroyed face of Reese.
"Let me show you the light."
"Yes." The SCP said, now placing the mask on itself.
A shudder ran through SCP-2217 as memories and facts ran into its brain. It cried out, "You promised!" before collapsing to the ground.
Faintly, it heard the door open. "Fire."
Everything went black.
Slowly, the mask was lifted off SCP-2217's dead body. Dr. Thompson had a tear fall and slide down his cheek. He turned from the guards to wipe it.
"You promised!"
A chunk of his heart felt like it died with that scream. "Place the mask in a new holding cube then leave me with SCP-2217."
"But sir-"
"Do it or I'll get you both demoted to D-class personnel to end up like him!" He pointed to Reese's mangled face and body, still oozing and dissolving.
The guards soon left, and the doctor cradled the fallen SCP's head. "Forgive me..."
The SCP stretched its arms as it sat up on the bed.
Dr. Thompson came inside. SCP-2217 smiled. "Hi, Doctor! I had the strangest dream... all I remember is a mask now."
The doctor's eyes slightly widened, but that went unnoticed by the SCP. "Interesting." He wrote that detail down on his paper. "Alright. Interview time, if you don't mind."
"Sure, Doc."
"Do you ever feel like committing suicide?"
"Nope. Life's too beautiful for that."
"And what of the symbol on your shoulder?"
"I don't know where it came from. I've had it as long as I can recall."
"Alright. It's time for another experiment."
"OK. I never remember what we do, though..."
"Don't worry, Hunter. Sometimes it's better that way." His eyes moistened very slightly.
So there was Chapter 2. Hope you liked it.
