The Narrator was, yet again, guiding Stanley through the halls and showcases of what he had planned for the second game, chatting about every detail of his plan and how wonderful he believed it would be. Finally, they arrived upon the machine the Narrator had created to give Stanley the broken achievement.
"Now, of course, it isn't functional quite yet, but in-"
...that wasn't supposed to happen. Stanley recieved the achievement. The machine didn't work yet, the Narrator hadn't fixed it- someone else fixed the machine.
".w..what - wait, what in the holy hell is going on? You got the achievement? Why did the machine work? Stanley, I didn't fix it, I didn't do anything to it! I swear it was broken just a second ago!"
He sounded panicked, sudden realizing something as his breathing quickened
"Who fixed it? Is someone here? Are we being watched? Oh god…"
he took a few deep breaths, mumbling "Composure… composure…", before continuing with false confidence, hoping to convince Stanley this was intended and trying to ignore the subtle feeling of eyes watching them both
"Yes, as you can see, the machine is working as normal, as I intended. It… um… it truly speaks to the awe inspiring magic of The Stanley Parable 2! Breathe… just breathe…"
Little did they know, you were watching them, silent as you had always been, quietly pulling the strings behind every little thing. The Narrator knew of your existence, he knew of your strength over him, over what he called his game, and it frightened him. You were a mystery, unknown, unspoken, not a line of dialogue he could see, able to speak directly to stanley without the Narrator even knowing you'd done it, everything about you frightened him.
