A lot of story out their ended with plot hole or a lot of unexplained things so why don't they do the same too? No one asks about that old scum so why don't they just end it like that? Yeah sure, it was told that he would be the final boss of the story but since the story ended happily, shouldn't they just let it go? Let it go!! Could have ended the last season with cliffhanger instead of a full happy ending then coming back with a whole bomb expecting everyone to take it because this is their fav story
