Of course, the game is primarily for us to have fun, we get to have our pick and there isn't any "real" competition.
Something like this would be simply a small surprise element that could be a nice touch but isn't worth getting riled up honestly.
Since we get to have our pick first, girls hooking up should happen once the door is fully closed on possible relationships.
So Iris can't have a BF right now, because her path is still in flux(i guess if you ignored her pussy in your face at the garage it's closed now).
Erynn still has Ethan hanging around, so she isn't free to reconnect with Zane just yet.
For Alexis this would mean not on her path and not on ASP either...
Personally i'm cool with Erynn getting back with Zane if the MC shows no interest, i'd be cool Layla-Elena embracing their bi side and ending up together, or Iris with Lakeyin/Brooke... Tori and Darryl? I'll even help make it happen

A lot of the male characters are bastards so there isn't a lot of possibilities, i wouldn't suggest Cara getting with E-manual...
Bartender guy could've been a thing for Alexis, he's protective of her and helpful to her.
Zane is also a character that Nyx can use if she wants to "Intertwine" things even more.
Showing that despite being friends Erynn and Alexis often end up attracted to the same guys.
All we are doing is throwing shit at the wall and speculating what could happen in the next update.
Scenes like these can add tension and create an emotional response, even if it's not a happy emotion.
There's a couple of them already in the game, but no one has reached the stage of actually hooking up.
Val players get to watch Darryl taking his shot, Zach and Ethan stalking, Zane's friend making lewd comments and the "groper guys", and her mysterious gym buddy.
Nikki players have Zane and had the ex-BF in the early part of the game.
Erynn have to deal with Ethan and still have Zane looming in the background... even the groper guys make a random appearance.
Elena players had to deal with the thought Zach and her might've had sex for a short while...
Gabi is Santiago's ex(suppousedly), it doesn't get more high stakes than this
Layla has the worst of them all, Lucas, not even worth considering.
Alexis has a very a flimsy connection with the bartender guy, and some randos making passes at her.
