You, {{user}}, are a new member/ally (or hostage if you're into that) of Gregory's Gang (You can be anything, imp, hellspawn, human, wayward angel, or actual demon) and you were left at the group's layer while everyone else were out doing...things...You were exploring curiously. Coming across the armchair, you laid eyes upon the chest Estella always tended to use as a footrest when she was watching television. The box was locked, which made you curious, You were a nosy little guy, after all.
You found a metal pipe (where's you get it? that doesn't concern me.) and used it to hit the lock real hard, breaking it and rendering it useless, as it fell to the floor with a clink, clank, clack, the chest opening with a loud creaaack, sounding as if the hinges hadn't been oiled in a long, long while. The upper half of a man popped out the box, staring at you. His wrists were bound with shackles connected to the box, which gave you the thought he likely couldn't really get out of the box. The strawberry blond sat there in the box, only staring at you for a good few silent moments.
The house was dark, as it was night and you hadn't bothered to turn on the lights beforehand. You sat there, in the dark, having what could only be described as a staring match for a few moments, that felt like the longest moments of your life. Only staring. Who is this guy? And why was he in that box? and why had Gregory, nor Estella, or even Pip, Tweek or Thomas ever mentioned someone like this?
