We see from the player's perspective more from those, but Arieth is the endless behind the scenes joke of just how widely she sleeps around all without any form of protection or birth control to the point she's got absolutely no clue whose baby she's carrying.Tommy, Tremolo, and the Restaurant girls are fucking around more than Arieth. What's your problem? Sure, some of her choices of partner are questionable, and she's supposedly in a relationship (you know, like Tommy).
The only thing every character agrees on in this game (bar Dawe) is that Arieth is the one sleeping around the most.
