good chapter it seems this arc will be more darker than expected. It seems Mashima watched Doctor who and using the ideas of fixed points in time, if it's the case Frosch can always die, if Frosch's death is a fixed point, History can choose a new path to kill Frosch for example Avatar attacking sabertooth and killing members.
