I posted something alike (after your post but before seeing it). I still like Josy, but on the Others' path. I think she'll dump Maya and join the party. I don't take her seriously anymore (Well... I never did... But if I were the kind of guy who takes those girls seriously, she'd be excluded from the possibilities... In fact, I'm like 8 or 80... Either others or Jill's path... The rest is just out of curiosity...).
By the way, good luck playing your extra 17 paths. After playing my main one (others path, sub-route Lily), the second one (Sage), besides what's already in every path, felt like it was just chit-chat and a scene that, though good, I could watch in the gallery. That's what I did for the 3 remaining paths initially, but, as I'm a curious guy, I ended up playing them. The only one I really enjoyed was Jill's. Bella's scene was amazing but I'd be content to see it in the gallery (as I said with Sage's), and the Maya & Josy path, I guess because they've already played a huge role in the main plot part of the episode, was like nil... I thought about playing Quinn, and Sarah & Melanie sub-routes of the others, but, since I don't think there's any relevant variation in this episode, I'll let them for the future.
I liked the party when I played it first on the Others' path (either with mushies or no mushies variations, but with mushies it's funnier), but, when I played again in the committed paths, it was a drag... I complained about having to choose a commitment at the end of the episode (I wouldn't say branch as the game is branched, at least, since episode 4) due to its incompatibility with some combinations of the affinity system (most precisely, the DIK affinity), but I think the problem runs deeper. I think it made replayability worse, since what is left in the routes after you take what is universal to all of them is, with some exceptions, just chit-chat and romantic/dating corny stuff. Of course, if you play your romantic path first, since it'll be mixed with the main plot parts, it'll feel less like that, but when you play your secondary routes, unless you part of the niche attracted to that stuff, you'll feel the drag. Moreover, I think the scheme of things, of free roams and parties, works better when you're non-committed... When you've already chosen a lover, those things start to make less sense...
I've started to wonder how the game will creatively survive until the end of season 4 (I say creatively because financially I don't doubt it can). Of course, in theory, the game could go on forever, until graduation or even after that, but, from the plot that we have until now, I think it's leaning to a conclusion that, if it extends for more than two episodes, I think it'll start to get depressing (besides, I don't think there's plot material to extend it more than that). Due to what happened at the end of this episode, if the next episode is filled with light parts and jokes, it'll be very, very awkward (unless the drama is solved at the beginning of the episode, but then it'll be a shitty exploitative cliffhanger).
P.S.: Geralt, sorry for the digression. I started to comment on your post but then went on to write more about my general feelings about the episode and the future of the game. I hope you don't mind.
EDIT: P.P.S.: I digressed so much that I forgot about that... Josy's not technically a "yandere"... She may be a spoiled li'l brat complaining about something she would do herself in an alternate timeline, but "yanderes" do crazy stuff, beat people, kidnap her "loved" ones, and so on... I don't think she'll go that far.
