I have been reading the thread here is what I have to say:
Yeah, it's pretty clear Alison sees Lena as a threat when Ian and Her go out in chapter 1 even from Lena's point of view she says she's being very passive-aggressive and she needs to calm down.
Also, I think it's interesting that if Lena and Cindy's relationship is low, she'll have the option to tell Wade she's not worth the trouble which surprised me. Honestly, I wouldn't be shocked if Lena saw Axel and Cindy together and was a bitch to Cindy if your relationship is bad with her in the future.
About Cindy Cuckold's storyline, I have a feeling he's going to find out in Chapter 12 because I have a bad feeling he's going to catch them having sex either at her place or somewhere on the Beach.
I'm curious if we do get a threesome if he's just FWB with both girls. Personally, I prefer Ian, Lena, and Holly Threesome more than everything given how much story surrounds the three even with the Love Triangle route that Ian and Lena can have for Holly while dating one or the other.
