My guess is he is refering to Jill. It doesnt really fit the other LIs. He has really been going overboard in showing Jill as "naive" in a lot of the recent dialogues, like the Banana costume or her talk with Maya/Sage in the cinema room. She was my "main" LI till this Episode, but man some of her dialogues ...Who are you referring to? Maya?
Anyway, I enjoyed the Episode, even tho the waiting time has obviously been a too long for what was delivered and how much money he is making. He could easily hire 2-3 talented people from SEA or eastern Europe to help render the generic stuff like dialogues (2 people standing in front of each other and talking doesnt require you to be an artistic genius), while focusing on the "lewd" scenes and emotional scenes where characters need the correct poses and expressions. This way an episode like this would probably only take 50-70% of the time this one took.
I wouldnt mind if he expands some of the "other" LIs, since those chars have partially even overtaken the old main LIs for me. Zoey, Lily and Mel are probably my three favorite rights now. Zoey and Lily are intriguing and could bring a breath of fresh air and Mel is just hot as fuck now. There will probably be no Sarah/Mel path, but if her and chars like Cammie get more scenes, yes please.
