There's a tendency among fans of the game to be very generous in reasoning away disjointed writing. The plot turns of a selfish, inconsistent or irrational Lena are totally fine. But they have to be justified smoothly enough in the text to not set off other readers' bullshit meters. I think the back-and-forth disagreements here are merely evidence the text wasn't handled smoothly enough in those situations, as these were also, of course, lock-outs and plot-turns of convenience based on development time limitations along with certain later plot-points and pairings Eva wanted to push.
Writing smoothly for such a magnitude of multi-paths, especially within such limitations, is assuredly tough though.
I think the main issue with the relationship talk when Lena’s slept with Jeremy, as well as Lena’s reaction to Ian+Holly, is that one of the protagonist sees a previous event in a different light than the player. Which is an issue when you’re having two protagonists and they’re interacting, because you can’t use other characters’ reasoning to apply limitations to our choices.
I agree that the writing in those scenes is a bit disjointed, but if Lena was an NPC, I think most would have accepted her reasoning without thinking that much about it. (Maybe that point is more valid with her reaction to Ian+Holly, as her reaction during the relationship talk depends on choices we’ve made ourselves.)
Having said that, Eva made the choice to have two protagonists with all the challenges it involves, and when you’re in the middle of the game, it’s the gaming experience and not the intricate writing challenges you care about. I’m not that bothered about those scenes myself, as I think they’re among a relatively small amount of flaws up until this point, but I can surely understand why it bugs some players.
