User blog comment:CNBA3/Future Filler Arcs (WARNING: ANIME WATCHERS, MANGA SPOILERS!!!)/@comment-24.90.187.181-20140628061907

I have actually thought a lot about this since there probably needs to be a lengthy filler arc in order to not catch up to the manga again so i came up with two ideas.My main rule is that it has to be a story that doesnt affect the status quo and doesnt seem like something Mashima will touch. 1.) Something with the exceeds from Edolas. Possibly the original slavers from the Tower of Heaven capturing the exceeds and putting them to work and FT has to rescue them. Can possibly have the reveal of parentage for Carla and Happy. 2.) A reappearance of the bad guys from the movie. Maybe the Prince wants to marry Hisui to unite the countries or something and they want to assassinate him while in Magnolia. Hisui calls on FT to protect her after experience with them in the GMGs. Can also help place the movie in canon and help determine when it would take place.
