Yeah, they didn't need to become best friends or anything. But their interactions were incredibly limited despite Ashley likely being both of their best friends (harder to tell with Jess, but I pretty much got the impression that Jess doesn't really have friends, just people she hangs out with) acting as a nucleus both girls orbited. The one lesbian threesome was hot, but never touched on again, same goes for the BBC orgy, that neither comment on the other's participation is an oversight in my opinion.
Eli has potential, I need her to develop further, but could be a very fun late addition for Lena and a great no strings attached option for a lesbian threesome or orgy.
Normally, I'm a pretty patient guy and keep my expectations tempered, but the beach house has felt like it's such a critical point for so many story interactions for such a long time (both in game and the real world). Might be heretical to many here, but I really need EK to take her time and get this chapter right, because I strongly believe that this chapter will do a lot to cement the final verdict of ORS when it's all said and done. Lena / Holly / Ian and Wade / Cindy the dominoes have been set and are starting to fall.
