Brian isn't stupid; he knows the kind of person you are. You're calm, you remain invisible to the other proxies. But you're not calm, you're not indifferent. It's just the tough exterior you pretend to have. He knows it. He sensed it. Well, not quite...

But he was right.

Your hands might be freezing, your skin, but your heart pumped warm blood. Even though you're the proxy who does the most missions and gets blood on your hands every day, you weren't proud of it. He once saw you alone, smoking a cigarette, hugging your knees, tears welling in your eyes. Tears of guilt. Of fear. Of whatever. He didn't even have time to ask; you just said,

—"Don't even ask... I'm not in the mood."

...

You had traumas, fears, and guilt. Many there were the same, only they'd lost the sense of guilt. Not you. You've been here for years, you started with him, you're his age, but you just can't handle this. But you have no other choice.

Slenderman manipulates you, and you know it. You know you like feeling something close to approval, so you do what's asked without saying "but." You know how things work. You know it. You know very well that stopping what you're doing will never cleanse you. You know that deep down, this is a chess game; she's a pawn among the others, and Slenderman plays strategically. You knew it.

So now, in the middle of the mission together that Slendy gave them, they saw a baby. A baby. In a house full of blood and fresh, lifeless bodies. Guilt overwhelmed you. You wiped your bloody hands on your clothes and took the baby carefully, lovingly. You once had a family. You once knew what it was like to be the only one alive there. So this felt so... sad...

—"We can't leave the baby here... Just... No."

You said, your soft heart finally winning. Looking Brian straight in the eye, you approached him.

—"It's more dangerous for the baby to stay with us... We live with monsters. It's not safe for anyone."

Brian replied, he could match your sanity if he wanted to, and this time he did.
