Didnt checked it, but are the madame Rose lewds even 60 FPS animations? I think they are only 30 fps... so there is a good chance DPC created the lewds for her already during the episode 8 DEV cycle. Wouldnt surpise me much if DPC created all the madame content in one go. And yeah all together madame rose dont have more than 100 still renders, not even 100. The animatiosn are rather short too. So... to create all the madame content it wouldnt take DPC more than one week. Nothing that delays a DEV cycle at all. Sometimes DPC creates stuff just to do something different. Madame Rose is something like that.
He either creates this stuff or gets bored and burned out doing the "regular" stuff. That was one of the main reasons for the interlude too. He needed that just to do something different for a while.
Its very likely he will do another interlude in my opinion after Season 3 to shake things up again and to gain some more energy for the last season.
Episode 9 and 10 together have already nearly the same amount of renders than the whole season 2 together.
Every single episode was growing bigger than the one before.
Episode 1 - 1301 still renders and 51 animations
episode 2 - 1709 still renders and 77 animations
Episode 3 - 2289 still renders and 99 animations
Episode 4 - 2532/134
Episode 5 - 2456/157 the only exception was kinda the same as episode 4 (funny how that is, ep 4 and 5 are my least favorites too, followed by EP9)
Episode 6 - 3336/162
Episode 7 - 3722/250 Huge increase of animations now, and in that timeframe DPC made a huge hardware upgrade too, since than he went nuts with animations
Episode 8 - 4158/358
After Episode 8 he did so much being a dik that he got a little tired of it, thats why he created the Interlude. And before that he started to create some side-characters just to mix things up a little more, like Nora and Sandy in ep 6 or Madame Rose later on. Its not that time-consuming to make side-girls which appears only once in a while, He did so in the past with Brandi or Rose from the Pink Rose, and will do so in the future, just to make something different here and there to mix things up for the game and his workflow.
Its obvious that DPC is somebody who gets bored easily creating the same stuff again and again. Which is another reason why he does everything himself, even creating music for the game for a while. He just needs that to keep things going. If he would focus too much on the maingirls and the popular sidegilrs like the majority of players want too, the game would already be abandoned.
So yeah all that considered, its very likely that he will do another interlude after season 3, and its more than understandable that he creates stuff like Madame Rose once in a while otherwise he would lose interest in the whole project.
Besides... 99% of the DEVs around here lose interest in their project pretty fast, most games dont even have more than 3000 renders and get boring VERY fast and you can sense that the DEVs just want to be done with the project at some point or are just milking and dont do actual work on the game alltogether.
DPC somehow managed to put out more and more content with each episode and keeps things interesting for us and himself by mixing things into the game that others dont do. Creating als the "unnecessary" stuff is kinda his secret to keep the fire alive i think. Without it, this game would certainly already been abandoned. So yeah... curse Madame Rose, Minigames, and other stuff all you want, i dont like many of those things either, but overall its the price to pay to keep things going i would say. And i certainly prefer to deal with those things during a playthrough and get a complete wholesome game in the end, rather than getting a rushed ending or even abrupt ending of a game with a bitter taste afterwards cause the DEVs lost interest in creating the same stuff all the time and are not enough commited to their "baby".
