It is not only a scene. Since my patch is built around the Prometheus one, but without any coordination/collaboration, my patch does not touch the rpa with it, in practice Prometheus (ehm), could need to take over the incest patch.Who knows, I'm not holding out any hope for it but it'd absolutely make my day for it to happen. Katherine is probably my favourite girl here and her and Myriam are so sweet together. Plus some good mother daughter incest is one of the rarest setups on this site and I think Katherine would be perfect for it.
Not a "legal" problem, I give the source with the patch, but means extra work for Prometheus.
Prometheus patch till now adds up some scenes, which change variable and allow the furry path, but otherwise do not change the main flux of the game - if one does not have the "furry lover" active, will see the same identical story, minus the sex with animals scenes.
Even my patch, does not change the flux of the game - I always said, and is a reason Zorlun has no problems with it, that I have no intention of changing the flux of the game, it his flux to manage.
The maximum I did was upping a variable already defined by Zorlun, and add in the dialogue with the shrink the possibility of the reference to incest - but that dialogue was already in the flux of the game.
Adding scenes with Katherine and Myriam doing stuff together, would seem to change the flux (a bit like doing stuff at school, means arriving too late at the gym to do stuff with Lucy, though if one cheats with URM, can change the variable and see the stuff at the school, go back to do stuff with Lucy, come back to the original path, and then change the variables so he has the game set as if he had done both things, though need to be careful that in future this does give errors).
If that is the case, it is something that would be very different from the way the Prometheus patch has been working till now - would not add some "parallel" stuff to the main flow of the game, would modify it, which would make it more complex to make.
