Crazy theory I'm probably wrong, August is Mavis and Zeref's son and Larcade is a clone of him or something like that, when he spoke of Zeref's son between light and dark and only his mother could bet him he meant himself. August said he does not understand love between parent and child and now has gone psycho seeing Cana and Gildarts.
