What does Mavis know about Natsu's fate? Could she know that Natsu might inadvertently use his full power like Dragon Force or Fire Dragon King Mode to at least overpower Zeref? Mavis might also develop something to help Natsu I guess. I bet next chapter, Natsu gets angry and inadvertently go full power.
