I just saw a picture of Natsu's scarf wrapped around Lucy's neck and it made me think.

We've already seen the scarf protect Natsu from Zeref's magic once. Maybe it'll also be the scarf that'll save Lucy from what flowed into her from the Book of E.N.D. . With supposedly all of Zeref's creations ending when he dies, whatever happened to Lucy should logically just disappear, but that would be rather anti-climatic. Better to have the call-back to Tenrou if you ask me.
