Considering everything D and F have already experienced and the way the earlier story was developing, I was expecting this plot line to be included much sooner with Cassandra - here we are, much later in the story and it is just now coming into play. At the risk of sounding accusatory, this smacks of 'milking the story', drawing it out and keeping the audience (and patrons) hanging on a bit longer. You see this in entertainment all the time...with television I call them 'filler episodes'. No big content, at least to the level of the original story and typically very vanilla by comparison to what has already been developed/shown. I would guess this home photography studio business will fill the next few episodes (say v0.31 - v0.35) with the only sex scenes including Cassandra, D and/or F; not really a complaint, just seems like more of the same for the foreseeable future.
How many times will we see a scene with F and D having sex with an occasional 3rd party included - with most of the 3rd party being lesbian action and, if you avoid the sharing route, that's it? Don't get me wrong, I see the work being done and respect the time being put in, it just seems like a lot of the same as far as the visual aspects of the VN go - I love seeing D's naked body, although there are SO many other opportunities that aren't being fleshed out (pun intended) - Olivia & Graham, Martin, Georgina, Rachel, Ryan, Jennifer, Elena, etc. We can only hope there are other branches being included in the releases for those of us that actually want to see more than D & F fucking over, and over and over and over and over...
