[Spoiler discussion] about season 3

So I thought about it, and I think that we'll get both arc 5 and 6, since we have to consider that arc 5 is a fighting arc, and while it takes a lot of paragraphs to describe a fight, in an anime entire chapters can happen in a few minutes, so arc 5 might take far less time than we think, so season 3 might have more episodes than season 2, but cover two arcs.
