I had seen what is going to happen in the manga. The anime really added quite a number of things which the manga didn't have.
Spoiler for Ep.79:
The expansion of Natsu and Happy reuniting with Lisanna with the flashback is kinda touching. This explains why Lisanna has a grave in front of the little hut he and Lisanna used to hang around with Happy other than the one at the church.
Lucy bullying Natsu scene was expanded as well. She uses more torturing techniques on him. Edo-Lucy commented how close Edo-Gray and Edo-Natsu are, always fawning over one another and Edo-Natsu crying on Edo-Gray shoulder like old times. "We are best bud, right?" and Natsu asking Edo-Gray to take off his clothes cracks me up. If I have not read the manga I would be imagining what kind of person Edo-Natsu is
. Edo-Lucy and Edo-Levy fights just like Natsu and Gray on Earthland while Earthland Lucy gets along with Levy.
Natsu, Wendy and Happy fantasizing about how reverse Edo-Erza would be like are hilarious though. Wait till they meet the fireball Edo-Natsu who was away. That would be "retribution"
.
