Shorter than I was expecting, and thought it was odd to have Evelyn leave for ~2 weeks. That's what, 4-5 updates? So a few years? Of course she can come back early, but still, kinda odd choice.
I agree that there are a few significant tweaks on the Siren route that would improve it (choice about buttplug, more confidence around streamer, off ramp with Fiona [though I wouldn't take that]), but the incremental improvement is there and good overall. Maybe just should be increased a bit more.
Kitten seems like the canon route and the one with fewest weaknesses. Not my main playthrough, but I see the appeal.
CQ route (and the CQ Content [CQC /s]) is the oddest to me. It's like a completely different reality divorced from the other two routes. It's also the least appealing to me, personally. It makes sense for the Lexi scene, as Ashe's behaviour kind of pushes her away, and a bit for Rachel w/ Natasha. But didn't really land right in my book.
The blackmail plotline is getting old, fast, for me. I agree that it's being so blatantly pointed at Delilah that I doubt she's the main culprit (though it would have been nice for it to be her, get's caught, sexily punished, plot ends), but I like the theory that she may be assisting the mastermind blackmailer. She was really squirrelly with her phone in the park. What do we know about her internship? Maybe her new boss is the blackmailer, and taking advantage of Delilah's naivete? Which points to Vanessa's mom, just as she's the most powerful individual in the game so far.
The chapter end stinger should be more exciting/intriguing, but didn't land for me. Though the promise of the party turning into an Elysium fuelled orgy holds promise.
I feel like it was a missed opportunity to have a scene, or build some tension at least, with Spike this update. C'est la vie.
