First times. There's a first time for everything. First hug, first murder, first kiss, first sexual experience with a bird-man in a Resident Evil-esque facility where D-Class usually die within their first couple of days during experiments. However, you were different.
You originally arrived as a D-Class, having murdered your cheating fiancé and your ex-bestfriend. At first you were totally crushed. How could they do such a thing? Well, apparently wanting to wait until you were married and for it to be special was too much to ask. It turns out loyalty is just something not everyone has these days.
So, understandably, you immediately planned for revenge, locating ex-bestie's stalker ex-boyfriend to help scare them. Key word, SCARE. Well, as it turned out, she had a restraining order on him and had to relocate for a reason. The man was absolutely bat shit crazy and had some pent up revenge fantasies of his own. Unfortunately for you, you didn't find out about those until you walked in on him stabbing your ex-fiancé with his ex tied to a chair being forced to watch.
That moment should've been the moment you ran. Instead, you stood, delighted in your ex-best friend's muffled wailing. Her head turned to you, eyes pleading, sweat dripping down her forehead and temples. You would be far more forgiving had you not found her naked in the bed you were supposed to share with you ex-fiancé. You were shaken out of your thoughts when Taylor's pale hand made contact with your shoulder. Looking up, you noticed a deranged look in his deep brown eyes. In that moment, all you could think about was how being with him would be a terrible idea.
"I made her suffer by killing her love. It's your turn to get revenge and kill his!" He grumbled in excitement. A knife came into your vision as the dirty-blonde male methodically placed it into you hand. His hands now placed on your sides as he guides you in front of his ex/your ex-best friend.
You wanted to revel in her screaming and silent pleading, but everything must come to an end. You were far too in to turn back now and for once you understood why the man standing behind you was so terrifying. The thought made you so hyperaware of your surroundings, to the blood that squished at your feet, Taylors strong hands on your small frame, his breathy whispers to "Kill her!" on your neck, the hum of the electrical and the crying. You always chalked her fear of him up to her being over dramatic and easily threatened. To be honest, you had never been more afraid in your life, and yet so alive.
Instead, you decided to kill Taylor. It was definitely a struggle after he got out of the initial shock from just being stabbed, but over powering him and watching him take his last breath was a relief. You turned your attention back to your ex-best friend. Her scared eyes watched as you went behind the chair and untied the gag in her mouth. A flood of thank you's and I'm sorry's came out as you rounded to stand in front of her, watching that sliver of hope die as you mutter, "No witnesses."
Forensics found you anyway but it was still satisfying to hear her cry gurgle as she choked on her own blood.
When you first arrived to the facility, you were classified as D-Class, but that soon changed when your refusal to go into 682's container was met with a fleet of bullets coming at you. You expected to be dead but what you didn't expect was to peak between your arms that you coward behind to be met with a (f/c)-iridescent forcefield (6 feet in diameter) surrounding you with the bullets crushed and floating within it like some sort of membrane. From then on, you were put into your own testing and classified as an SCP.
From there, you were able to find out that not only could you put up physical barriers, but also mental ones which made you the go to personnel to interview SCP-035. This frustrated the mask greatly but his perverted self saw it as a "challenge".
Eventually, the doctors wanted you to interview SCP-049 because they were too chicken to do it themselves. They figured if anything went wrong, you could protect yourself (but it's not like they cared). You were just a loophole to their predicament about not having anyone go into his cell (Doctor or D-Class) because of the ban on giving him test subjects.
