Okay but hear me out

You know how people will sometimes mute their dogs because they’re too loud by cutting their vocal cords (I do not condone this practice whatsoever I think it’s horrific and inhumaine)?

What if like,,, that happened in the box boy universe? A particular loud and rebellious boy gets taken to the vet and gets the surgery done, comes back unable to speak? A cruel whumper cuts the cords of a quiet box boy just because they can? A whumper tries to cut the vocal cords themselves in a fit of fury?

Then the box boy has to suffer in compete silence, only able to let out broken wheezes? A box boy tries to scream for help when they manage to get out but to no avail? There are so many opportunities...
