I definitely can see the side glance to the Rebecca content as it isn't my cup of tea as well, so my choice was to think before opening the door. I can't go for direct quotes and my memory is fuzzy with past Chapter content but it is possible that Sterling didn't go complete ape-shit because he has brought up topics of animal fucking I believe(pigs I think, I can be completely wrong so take my shit memory with a grain of salt, ill probably fire up another play-through later).
For those that are ready to bail, I would probably hold on to that. Rebecca doesn't seem to be as big of a main attraction so this could just be the end or at least a break from anything related to her, not to mention this Chapter we have introductions and hints to others that will/could be in the remaining 2-3 Chapters:
Keira(and potentially her mother as a surprise visit when she comes), Tsukiko(Kumiko's eldest), the youngest daughter of Kumiko's family(was mentioned that they celebrated her youngest childs 18th birthday), and someone named Lisa(Catherine friend) who is back from vacation(unless im missing a reference from past Chapters). Edit: Eileen(Drew's gf), Flora(Tiff's mom), thanks Fayn.
So some could breathe easy that there are other things on the way and most likely won't see any more Kibbles and Bits in your face.
