AHHHHH wtf! The beta took away the 3some with Jeremy and Louisa if Lena is dating Ian. Laaaaaaame. She's already got a hard big black cock fetish (no pun intended) from flirting and perving and blowing jeremy, let her have fun!
Fair enough. But I think there should be substitutes to that threesome scene:
if Jeremy's relationship with Ian is low, and Lena was already blowing Jeremy, Jeremy should still ask Louise to ask Lena to have threesome with Louse and Jeremy. And since Lena wanted her relationship with Ian to work, she would reject the offer.
If Jeremy's relationship with Ian is high, during Lena's concert at the fortress (where Louise ask Lena for threesome), Lena found that Louise was distracted and asked her why. Then Louise told Lena that she felt uncomfortable due to Jeremy was planning to have a threesome between Louise, Jeremy and either Jessica (if Jeremy already fuck her) or with Alison.
So the end result of both condition above is that when the threesome actually happened, Lena who just got home, heard the noise from Louise bedroom and decided to have a peek (just like first time before). And when she saw Jeremy nailed Jessica or Alison, if Lena's fetish is threesome or big cock, she feels the regret that it was supposed to be her who got nailed by Jeremy's big cock.
