This comment will probably get lost in the throng, but I really feel like the Ellie/Julia event was a mixed bag. On the one hand, it was hot as fuck seeing Sophia and Julia going at it, but how it came to be feels like it was executed poorly.
For starters, it just felt really forced, not only by having Sophia there with them, but the way that Ellie just so casually and blatantly spills pretty much every little detail about her and Julia. It was so direct and straightforward that it just felt really out of place and, at times, cringy. It was a bit too descriptive and mushy, and felt more like an entry in Ellie's diary than something she would say in conversation with her mother.
It also feels like too rapid a change given that Ellie said after the kiss that she needed time to think about it all, but then reveals here that they've been doing a lot with each other over the last 3 days. So how long did she take to figure things out? 2 hours? Seems like it didn't take her that long to decide to commit to whatever this is she has with Julia only for the sake of giving us this scene which, again, is hot as fuck, but felt like it was just to push that envelope in a rather contrived way.
A better alternative might have been if this was Ellie and Julia hanging out for the first time since that kiss, and Ellie invites Sophia to hang out with them because she's secretly worried it might be awkward. She doesn't say that to Sophia, but she picks up on it. The 3 would then hang out and chat for a bit before Sophia gets a call from Alyssa asking if she wants to go shopping which she agrees to or doesn't saying she has to pick up Dylan. Then, in either case, Sophia goes inside to change and then goes back down to the kitchen and becomes curious about the girls so she spies on them again which would be when Ellie and Julia talk about things and Ellie decides to take things further with Julia which Sophia would watch and be turned on by.
It sounds a little less hot than what we got, but at least it would've felt like more natural progress and would still peak Sophia's lesbian temptation, plus we'd have seen some action between Ellie and Julia rather than just being told about it.
