actually, we don’t know it’s incest for sure. remember in season six when derek was with elizabeth and garte and zach? elizabeth mentioned that he had cheated on aphmau’s mom with another woman, therefor, ein and aph could be step siblings. plus if ein WAS sylvana’s kid wouldn’t she want to keep him with aph and raise him? there was also no parenting agreement mentioned, so that also proves that ein’s mom isn’t sylvana. plus remember when zach got mad because he “couldn’t see his daughter”, he would have been mad about not seeing his son ein either, but wait, he can, because it’s zach and that other woman’s kid. also in s6 it mentions that zach has a son, but never specified if it was sylvana’s kid too.
