Okay, just finished this episode, and as some said, in the beggining i wasn't feeling it, but it ended up great, my previous grivences about Cathy still stand, even more so after talking to other girls on the swiper app, and kissing Sage, there is no reason why the MC in the relationship with Josy and Maya wouldn't take things with Cathy further, maybe i did something wrong on the play through, my dude is mostly Neutral, so maybe that is that, but i would have liked to have been given the option of continuing things or not.
Your affinity doesn't matter, it really does come down to whether or not you're on the M&J path, which I'll agree does kinda suck, but then I feel it might have something to do with giving players alternate events later on.
For example, there could be an event in ep 6 or 7 on the threesome path with the MC, Maya, and Josy, but those not on the path wouldn't get it and thus the episode for those players would be shorter, just as it was in this one without the M or J sex scene and "picnic" scene. Therefore, by putting Cathy on the non-M&J path, DPC could make it so that, in place of a M&J scene, there's a Cathy scene instead.
That could be why the Cathy stuff will go no further on the M&J path, but I do however wish we could still at least sext her. Sure, there's the risk of getting caught, but Cathy could really do with having a guy give her the kind of attention she deserves and she had one who was ready, willing, and able to do that but then it just ended abruptly.
Hopefully DPC will retcon this if enough people complain about it just like how they seem to have tried to retcon the whole M&J situation on both paths, but if not, well, c'est la vie.
