Ellie is Zoro's Wife

The Straw Hats were in a rather large and festive tavern, on an island they were stopping on… it was some sort of holiday, so Luffy was obviously drawn in by the celebration

Zoro seemed rather unamused at the whole place, alone, leaning on a wall in the corner of the tavern. Then Ellie walks over

He eyed you up and down for a second, already assuming what EllIe wanted, Zoro spoke

“I’m not going to dance, if that’s what you came over to ask me, my dear wife”
