I wonder if for once they decided to give a true boost not only to Lucy's power but her motivations as well. Mashima always wanted her to be a girl with no interest in "strenght", someone that just want to enjoy her adventures and write books. But considering the kind of situations she keep facing, and the constant shonenshit-raise in powerlevel of the enemies, inwhich once you defeat god then they discover it exist ultra-god, and then the god of the gods... (well... basically dragon ball), and the fact that the way she is, she is totally out of place in Natsu's group (seriously why sending "her" to complete such a quest that require Gildartz/Laxus powerlevels?), all this make this mindset completely out of place. She totally need to want to become badass. Even just for self preservation. If not for being always strategically paired with the weakest opponent she would have been killed long ago.

Yeah, very likely a reminder.
