Site-17 Safe Wing
On the Safe Wing, boredom reigned supreme for every Agent assigned to the Safe Wing.
The other Agents on the Euclid and Keter wings normally wish they were over there so that they wouldn't suffer a loss of life, loss of limb, mutation, or a combination of the three. They would get jealous of the Agents there because they get to read books, watch over loud clocks and beautiful paintings on the walls.
The Safe Wing Agents, also, hate being there. There was nothing to do, not much to talk about since their SCPs are always locked up safely. From a glancing view, one could almost guess they want a containment breach to happen so they could spring into action. They were always on the edge of their seats, like a hunter waiting for its prey.
This persisted for some time until a breach occurred not far from them. A majority of the Agents mobilised to re-contain the escaped anomaly since protocol dictated that at least a containment unit must remain to make sure the Safe Class skips aren't going to breach their containment.
However, the containment team didn't have to move out to perform their duties. The rouge skip was drawn away from them so they couldn't do much. They were fine.
What the team wasn't suspecting, however, was a tactical genius and mastermind of all things to come.
Its name was Tubbioca or to most people within the Foundation, SCP-4966.
Agent Mason Groves arrived at work late that morning, going through the standard checks and security clearing as everyone else does every single day. Mason rushed in, wearing his full body armour, his belt of black pouches, a green first aid pouch and baton, and rushed inside past the residential wings and office blocks. The wings were evacuated. Only the security teams, MTF members, and research personnel who were too stubborn to leave remained on site.
As Mason kept sweeping the corridors, the alarm suddenly ceased. He relaxed a bit and saw where he was on his Foundation-approved mobile. The Safe Wing, he was in there. He chortled for a bit and thought he might as well make his course around the Wing just in case something unfortunate got through to the skips or someone used the breach for their advantage.
Mason strolled past many anomalies that were secured nicely in their cells. He stopped outside SCP-4966 containment chamber and peered in. He couldn't detect where it was, so he cautiously stepped inside to locate where the plushie went to.
He swept left and right, but nothing was there. So he moved up to the bed where 4966 liked to be in and had a quick peek of the bump in the sheets. Sure enough, he saw the grey pillow that 4966 tends to look like, satisfied that it's sleeping and proceeded to exit the chamber.
Mason appeared at the office and looked inside. Here he was supposed to tell the Doctor in charge about where he was at the time of the containment breach. So Mason was surprised that the Doctor wasn't in their office at all or that anyone even worked inside the room.
Mason gave the door a soft knock, and he suddenly heard a thump underneath the desk, followed by someone saying "Ow". Mason looked over the desk and saw a woman in a lab coat on the floor, stroking her head with one hand and holding a cable in the other.
"Uh, Doctor?" Mason said as he was studying the Doctor on the floor. Her wavy hair was being brushed away from her face, revealing her flushed cheeks, which were a sharp contrast to her fair skin tone. She looked up and saw the stoic Agent standing over the desk. The Doctor suddenly squeaked and stood up. She would be considered short by an average person, but she came up to just below Mason's chest which would have intimidated most people. However, the Doctor just smiled and sat down on her chair.
The Doctor gestured Mason to sit down and, as he did so, the Doctor put on her ID lanyard and grabbed a pair of glasses from her lab coat to put on.
"Sorry if I was interrupting something Doctor…?"
The Doctor smiled. "Dr. Niles Hessen and I only just arrived a few days ago. I'm in charge of the Safe Wing here until someone else can cover the Admin."
Ah, thought Mason. He had never met Dr. Hessen over the past week as he was mostly on Euclid watch for the majority of that time.
"So," Niles piped up and drew Mason's attention. "What can Dr. Hessen do for you?"
"Well, I got to report my whereabouts to you. Seeing as there was a containment breach happening."
Niles's eyes went wide as soon as containment breach left Mason's mouth. "There was a containment breach?"
"Yes, ma'am."
"That would explain the computer going off then. Thought I accidentally kicked the off switch, hehe…"
Mason just stared at the cable on the desk then back at Niles. "Uh-huh. Sorry, but could we do the form so I can do my job?"
"Ah yes, so you're here for the MAL forms?" She then pulled out the forms and wrote on them accordingly as Mason talked about where he was during the day. Everything from where he was in the morning to his car drive to now.
Niles placed the pen down and nodded, satisfied with the paperwork. She looked up at Mason. "You can go now, mister Groves."
"Thanks," Mason got up and walked to the door. As he did so, Niles noted that he had a grey bag on his hip but thought nothing of it, seeing as how Agents wear whatever was needed to do their job.
After a long day of keeping several skips contained by following their files, Mason drove down the road to his home just over the Canadian border. He was going through his day full of paperwork, re-writing containment procedures so that they're up to date, and dealing with Agent Jackson.
He hated working with that stuck-up prick, but he wasn't going to complain because it's his job to look after the anomalies. He does what he can, with whoever he can, even if they're only in this life for the money or for a step on the ladder.
Sometimes it's both. This is what mostly kills the new Agents first.
He got back to his house in what people would call paradise. His neighbours would see a lovely two-storey house with a nicely cut garden, a nicely built patio and a glorious view of the sunset every evening. Mason, unfortunately, cannot see the sunset most days, thanks to working at the Foundation but its what pays the bills.
To everyone, the street is called "Sappy Cherry Park Lane". A gated community to an outside observer but inside are multiple cameras in case people are doing something not agreeable with the Foundation's rules. SCP Lane didn't need security, as the neighbourhood had Agents and Researchers with combat experience from Site 17 living in every single household.
Mason walked through his spruce front door and was greeted by his daughter, Marron, coming to him with the happiest smile a father could love. Her blonde hair and brown eyes were what made Mason's day, no matter what horrors he faced, just that little bit special.
"Daddy!" Marron exclaimed and jumped up to her father's arms. She was then lifted up into the air by Mason's big arms. "How was work, daddy?"
"Honey," he spoke like he always does when he talks with Marron, with a smile on his face and love in his voice. "You know I can't talk about work."
"Awwww…"
"But I did meet the most horrible thing you'll ever see."
"Yeah?"
"Yeah, it was called Father Tickles!"
And with that, he played with his daughter and laughed whenever she tried to tickle him, which were the best fifteen minutes ever before she fell asleep in his arms. He got up and saw the babysitter was waiting for him in the hallway. Mason paid the babysitter, and he took Marron to her bedroom. Making sure she was safe and sound in her bed.
In the early hours of the Sunday morning, Mason was able to sleep soundly. He was comforted by the fact that Sunday's the only days off he gets. He got up, dressed in his workout gear and did his morning exercise. Mason regularly runs one and a half kilo run across the field just outside his house, a few pull-ups in the forest and a couple of push-ups before racing back home to greet Marron.
He got back and saw Marron eating cookies with a cute plushie. Mason always admired his daughter's imagination, playing tea parties with her dollies, plushies and teddy bears. She sometimes even pretends to be her big macho father and wrestles her stuffed animals to "lock them up".
But, this plushie is one that Mason has never seen before. It was grey and plain-looking, yet oddly charming. He cannot remember ever buying a grey, cute plushie like the one Marron is feeding cookies to. However, since he had a daughter who loved having a cute toy every time they left the house, store, beach or anywhere that can sell them, he can't remember all of the toys that Marron wants.
He watched her feed the plushie for a bit. It's so amusing how they come up with their designs, especially a movable mouth and all, so he left them to it as he went upstairs to get changed.
As he was getting changed, his phone was going off. He flipped it open and saw who was calling him. An unknown number from Alaska.
"Hello," Mason answered.
"Agent Groves," the unmistakable voice of Niles Hessen was on the other end of the phone. She didn't sound as composed as she was yesterday.
"Ah hello Doctor," Mason said in his neutral tone. "How can I help?"
"We got a problem, and you're needed on-site ASAP."
"Sorry, doc. But today is my day off, and my daughter is looking forward to having me be -"
"SCP-4966 is missing."
Mason realised what was happening. 4966 went missing, and he was the last one to enter its chamber, which means he's about to be under the watchful eye of the Foundation. He double-checked his connection was secure before going further. "All right, I'll be in shortly."
"Thanks," Niles said, regaining some composure now that Mason's coming in. "We aren't going to get the higher-ups involved. It's just going to be me, you and a third party member that's going to be chosen by me. I figured I should tell you in case you assumed that it's going to be the SCP Inquisition."
Mason said nothing but he did sigh relief. He thanked Niles on the phone and hanged up, grabbing his uniform and heading out to the car. Marron looked at him with a bit of sadness, but he stroked her hair and kissed her forehead.
"Daddy's going to work now. Look after the place while I'm gone, okay?"
"Don't worry daddy, Tubby and I will Secure the house, Contain the food and Protect the TV!"
That's my girl, Mason thought to himself as he left through the front door.
Marron went back to her table and saw the grey plushie, writing words on a piece of paper with a red crayon in its tiny paws.
TUBBY
WANTZ
MUNCHIEZ
Marron giggled and picked up Tubby. Playing with the adorable plushie while taking him to the fridge for Marron to make peanut butter and jelly sandwiches, she grabbed a big tube of Pringles and was feeding her new friend some delicious munchies.
Tubby then thought to himself that his life is good. He now has an unlimited amount of munchies, a new best friend, and a large spacious room.
Tubby is happy.
