I have to echo what other have said, kind of disappointing on the adult side of things. That's balanced out to some extent by being by far the best story update so far, but this is still an erotic game at its core.
As someone who's not really into any the genres this game is based on (monster, non-consensual, etc), I started playing this pretty much exclusively for Sarah, and to a secondary extent for the other attractive character models (like the cop from the intro). I'm aware that I'm not really the target audience for this, so I try to keep this in mind as I react, but in the past every update has had stuff I really liked, like the zombie setting and some scenes with Sarah. The Ava stuff I treat as pure story because the adult aspect isn't appealing to me.
For those reasons, the scene in the gymnasium with the hooligans is my favorite by far. Sarah finally having a full scene, and with humans to boot. And I feel like this update passed up on a golden opportunity to have another one like that. Having established that Sarah is still under the aphrodisiac effect and that it distracts her, there was the perfect opening for another full sex scene with a human before she goes back out to monsterland. Instead of her just touching herself (in an update where there is another masturbation scene, to boot), have her fuck one of the soldiers due to her lust. The officer she shittalked previously (Graves I think) is perfect for this. It could have some of the conflict that is innate to this game, and end up in basically a hatefuck.
It would have been a nice bone to throw to me and any other vanilla-enjoyers who are along for the ride by having another fully human sex scene before Sarah heads back off to almost certainly get into all sorts of monster encounters. Again I know I'm not the target audience so I get not being catered to (especially since I'm on a pirate site), but in this case it would have sacrificed nothing, and even plugged what many consider to be a hole in this episode (lack of meaningful sex scenes).
