So these are rough translations and kinda hard to read but Erza is saying
“No weapon in the world would work. Especially since the dragon cry no longer exists.”
That means that everything that happened in the movie actually happened which means every nalu moment in that IS VALID.
I don’t mean to turn this into an annoying Nalu post (
im pretty sure i say that in every post i make lol) but Dragon Cry shows a lot of how Natsu sees Lucy which we don’t normally get in the manga. A lot of people like to think Nalu is one sided because we always only get Lucy’s reaction to their moments, which I don’t agree that it’s one sided at all but I will say I wish we saw more of Natsu’s perspective…
BUT NOW with this in the Manga it makes me so happy it’s confirmed because in that film you see more of Natsu side of things. ***Spoiler from the movie*** Especially that pretty ass flashback Natsu has of her when he’s unconscious. oml
