if Mc were generous, he would only need to impregnate Maya to convince Patrick, regardless of whether or not he is having an affair with her
That reminds me, I saw a meme where Patrick was cheering on MC pumping his daughter full of cum, but freaking out over Derek fucking the dried up old granny. I can't remember if I saw it here or on the subreddit. Anyway, Maya's more than happy getting creampied now, I'm sure MC's super sperm will give Patrick that grandchild any day now. Probably have to wait for the goddamn epilogue though

Best case scenario regarding pregnancies, we might hear that our love interest just found out she's expecting before the epilogue, probably have a bit of foreshadowing with some morning sickness mistaken for a hangover. Except for maybe Nora, whose story involves wanting a child, so she could start showing well before the end.
