I think the point is she's trying to get the money by making the MC impregnate her, so if you creampied her in the garage scene in one earlier episode, then she is actually pregnant of the MC and gets the money, while if you refused the garage sex she try to pretend she's already pregnant in hope that you creampie her now believing that there's no point in trying to avoid a pregnancy that is already going on.So did I mess up or did Bella get pregnant with someone else to take the MCs money? I somehow messed up my Bella/Joe path and recreated it. I said I wasn't trying to get her pregnant but she is. She also gets REALLY loud about cumming in her. I refused. Girl is crazy!
If you fall in the trap, probably she will actually get pregnant of the MC and gets her share of the inheritance.
If you refused to creampie she's not actually pregnant and gets no money.
This is just my speculation because I didn't inspect the code.
But her being pregnant of another man and tricking the MC in believing he were the father would have made sense before paternity test was a thing, not in 21st century.
