I think Cat already knows the truth, from the last time MC visited Sophie's house, she also told MC how Sophie reacted to the news.
Amy yeah will be in a bit of a weird spot, with conflicting loyalties, then there is little doubt a big part of those loyalties lie with her sister and her little man beyond what many consider right or wrong.
For that guy who called the dev lazy for having no animations, well it is clear he is incapable of looking further then the length of his nose and did not even watch OP.
If he had, he would have seen another game from same dev with animations actually and if then would have started a search to find out what that same dev said about it. That it was an experiment and in his eyes the experiment failed since even at very best and that would be with all winds in sails, no cockups ever and a very optimistic prognosis about getting faster making animations it would increase development time by at least factor 2.5.
Besides this those animations did not add much to that game in my own opinion and same goes for about any game with animated sex scenes with a few exceptions that also have serious text lines in the animations going beyond an urgh, aggh or it feels good.
Real good animated sex scenes that also have some feeling to them are rarer as a dodo unfortunately. Maybe two hand full of games have them and those tend to release bloody slowly, three months or more for two minutes to 10 minutes of play often as well. Animations used to portray emotions outside sex scenes actually tend to add more as animated sex scenes in my not so humble opinion,
So please give me Grandma's house as is, even if imperfect and let me enjoy myself every two weeks. Instead of getting a worse product every two months.
