bye bye Lucy

Natsu and Lucy are really close friends.
but when Lissana comes back from Edolas no one seemed to know her or talk to her anymore. Natsu eventually kicked her off his team for Lissana and complaining that she was too flimsy. She decides to fake her death and leave Fairy Tail for good. She thinks about all of the things natsu did and she goes back for revenge. What will happen in the book???
