I'm not giving plot spoilers here and I haven't completed the game yet, I'm just going to talk about a few weird tangential things that have popped up so far.
First off, 'Lotus'.
Has large breasts (really, they're bigger than that in-game!) and is wearing a skimpy belly-dancer outfit. We have no idea why - the characters are choosing not to talk much about themselves in case the killer is listening. It doesn't surprise me that people occasionally question her unusual appearance.
However, what isn't apparent from that image is that she's a lot older than the main character. I don't know her age exactly so far, maybe 40? But while this is a surprise to the player, it's supposedly evident to the other characters, some of whom call her 'Grandma' and complain about having to look at her "wrinkly raisin" body. This seems... strange, compared to the visual that's being shoved at the player. Are we supposed to assume that the characters making these complaints are being ridiculous? Is this intended as commentary on the 'christmas cake' phenomenon, to suggest that a woman over 25, no matter how conventionally attractive, is over the hill and unwanted? Are we supposed to assume that she looks extremely different from the depiction on-screen, and that the Giant Shiny Breasts are just for the player's entertainment? That has weird implications of its own... And are we then meant to agree that looking at cleavage which is not excessively youthful and perky is a horrific experience?
Another thing that made me blink in confusion was that, while examining one of the rooms and encountering a vanity table, one of the characters suddenly went off on a rant about the derivation of the term and how "women every day sit and stare at their own conceited natures" or something along those lines. Which, well, whoa, there's a lot to unpack there. It's possible that this is meant as a sign that the character speaking is a jerk, as I have yet to unravel the central mystery and I strongly distrust that particular character. If it's just an out-of-the-blue tidbit by the author along the lines of the rambling about telepathy and crystals, it's... creepy.
