There's some sort of story to this image, I think.
She doesn't look all that alarmed, despite apparently being a prisoner here with her jacket and gag making sure she's mute and impotent. The headphones with the music player suggest she was given a choice to have them, even if she can't press the buttons. The normal jacket on the cot gives it an almost casual air. Like she voluntarily slipped out of her clothes and let herself be placed in bondage as a means of relaxation.
And yet, her staring at the Earth suggests she misses it, or at least wonders what's going on back on the surface.
Is she a prisoner here? Or is a life of mute immobility better than anything outside that room?
Whether voluntarily isolated or not.... would she want to leave that cell, if she could?
