Aurora's father patronized elves during the Red Emperor's reign, but she is a human (appearance - standard ears). If we oriented on the game's code, then pregnancy is confirmed for Spring, Val and Valeria (Aurora/Isis has a mc's children - "moon" vision of future).
So I explored how Lazy Monkey codes, so apparently if there is a scene, then maybe later on, the scene variable will be called up to put in the pregnancy.
For example in the elin scene, the game nor its outcomes are shown with Elinpregnancy variable instead you get the scene. But when the cat scene comes around, and you have the elinscene, then it automatically gets the elinpregnancy = 1.
So I am assuming that for some characters like valeria, the farm girls, josephine and others they get the scene and have a pregnancy variable set later. Because we do have the creampie count for cass, ophelia, val and the wives.
