Well it did kinda appeared out of blue , cause the ideea of the requested scenes was taken into consideration recently. They probable never intended if it wasnt for that. I mean if they did they wouldve put it season 1 some scenes too.Tbh... from a realistic point, and a good design perspective... it should be added the moment that kind of polarising content is added. especially when it is one that clashes hard with the main genre and main demographic (being incest/harem).
