Easy to see this short story, beautiful crafted at whole, as one about doppelgänger. I saw it as familiar state reflection; after long , tough work days, the intense fatigue , making you almost catatonic, can offer a lot of strange illusions. Or in the womb of flu.
But , sure, it is only a profound subjective interpretation. What real matters is the image - the blue serves a lot - , the music, and not last, the acting Jordan Eichholtz proposing just fair portrait of lonely man in bathroom discovering himself as other, not one defined by noble intentions.
Not the less, the admirable virtue is the wisdom of use in perfect manner the three minutes for a beautiful storytelling.
