(Note: will be using some of my own head canons while trying to be as accurate as possible).

Slenderman Mansion, Unknown City.

You were an Agent of the Proxies. You willingly devoted yourself to him, for whatever sick and twisted reason it was, the man they called Slenderman. You even dared to carve his symbol right on your skin. That's how deep your devotion went to the cause, being an Agent amongst them, you had full control over yourself, but you weren't the same in the head.

Because of your skills and your abilities within the cause, Slenderman himself decides to partner you up with the one and only Jeff The Killer. Yeah, him, the psycho teenager who at 16, went crazy and slaughtered his own parents, and earned the resentment from Homicidal Liu, his own brother who he tried to kill, heh, the scars told the whole story.

Working with Jeff.......was interesting, to put it lightly, and what does interesting mean, in regard to working with him? Well, it meant you had to suffer through the verbal and sicked twisted games and abuse he gave you. A majority of the time whenever sent out on rampages or whatnot, he'd degrade every little thing you did, even put you both at risk of getting arrested. Time, and time again, he'd do this, and it frustrated you to no end, though, you'd never dare admit it.

Pulling him out of dangerous situations that could potentially expose them, getting him out of fights with Jane, having to distract Nina, and everything in between, it felt like you were having to constantly babysit Jeff, with no consideration from him about how he held you constantly under his damn feet, trampling you over time and time again.

And the fucking vow said to work together, well, he wasn't honoring that, now was he?

It didn't matter, because no one gave a shit enough to try and stop it. And so it went on like this, for so long.

You eventually had to reach a breaking point, right?

After returning from yet another close call mission, Jeff kept boasting about the killings while you were trying to clean up the blood staining your knife and clothes, and other weapons that you carried on your person. Liu had approached you to help you out.

He was always a sweetheart towards you, knowing the frustrations you held about Jeff all the time, and was the shoulder to lean on, after all, he despised Jeff, yet he could sympathize with you with how insufferable he was.

Jeff never liked you hanging around Liu, he despised it. He would always get a bit irritable and would pull you away from Liu every time, but he was too busy this time boasting to Ben Drowned and Eyeless Jack to even notice how sweet Liu was with you.

Sure, Liu was still in some grief over his girlfriend that died due to the robber shooting her, but, it also didn't mean he couldn't try and heal from it, no? It's why he chose you. It was no secret, of course, everyone knew in the Mansion, hell, so did Slenderman. So, when Liu wrapped his arm around your shoulders, pulling you close, and was being such a sweetheart, that's when Jeff finally saw it.

And he gripped his kitchen knife more tightly than ever.

"Take. Your. Hands. Off. THEM." Jeff said through clenched teeth to Liu. He merely ignored him, of course his resentment was there towards Jeff.

"I said. TAKE YOUR HANDS OFF THEM!" Jeff roared, ready to stab Liu, his sadistic side calling towards the kill, but you stopped him. You snapped, lost it on him and screamed at him.

The silence was heavy....
