(view spoiler)[I loved this book, but I felt lost by one of the plot twists at the very end. Did he discover that his father was forced to kill his mother? That is one heck of a dystopian plot twist, but it is the only thing that makes sense once the mildew plot twist unfolds. Am I misunderstanding this? (hide spoiler)]
This answer contains spoilers… (view spoiler)[I thought the revelation here was confusing, too, but I interpreted it differently: Eddie sees that his mother had about 50% colour perception, and his father even less -- meaning that his own colour perception should have been significantly less than the ~70% he scored. In other words, there had to be someone else's genetics in the mix. He underscores this by asking who his real (genetic) father is. (hide spoiler)]
This answer contains spoilers… (view spoiler)[The book actually says that Eddie's father did not kill his mother, as he was not "her attendant Swatchman". Presumably she was shown it by someone else, and Eddie's father couldn't fight it because it's the Rules, and might have drawn attention to him having never shown anyone the Mildew (book also states Eddie's father had never lost a patient to the Mildew).

Christine I assumed that someone else showed her the Mildew. Maybe while he was out of town or maybe for revenge? It is left vague through.
Rizza Yvette I didn't even think of that! A friend mentioned to me that he thinks Eddie's dad definitely knows about mildew because he tells Eddie he's going to stay in East Carmine and continue Ochre's work (aka keep the town mildew free). To me it didn't imply that he knows, but if he had to kill his own wife maybe he does. I, however, don't think this is something Eddie has discovered, or realized yet.
