It’s extraordinarily apparent in Metal Gear Solid that the camera treats different characters differently. Quiet is an exceptionally objectified character — not just because she’s scantily clad, but because she’s very much treated as a fetish object in a number of scenes. Some enterprising individuals took the PC version of the game and swapped Revolver Ocelot’s and Quiet’s character models, so that the game treats Ocelot’s model the way it ordinarily treats Quiet’s. It’s very telling.
And that’s not even to discuss Quiet’s origins, that she’s basically a plant who absorbs light and nutrients and water and air through her skin, and that putting clothing on her effectively suffocates her — never mind that her taking a shower should be akin to drowning, as a result. The supernatural elements (explained by a parasite) are there to justify having a bikini babe in the game who’s set up to have sensual showers in front of people on more than one occasion.
This is, of course, a secret cutscene, available only if you spend three days in a dumpster and have a full bond level with Quiet.
