A/N: Just a little ficlet I wrote based on the prompt Reliance. This is what I get for re-watching all the One Piece episodes. Right after the Skypeia arc. Friendship Sanji/Usopp, though you're free to read into it. XD
Once Chopper finally deems their cook healthy enough to return to the kitchen – much to the relief of everyone; Nami refuses to acknowledge her poor cooking skills and no one else wants to bother with the task after dethroning a god – Sanji asks her who had pulled him from Enel's ark. Perhaps a matter of principle and pride to know his savior when he'd essentially forfeited his life for the crew, she muses before answering.
"According to Navigator-san, Long Nose-kun went back for you." There's a slight smile playing on her lips, and even she can barely suppress a chuckle at his subtle shock. He quickly hides it by turning his head, chewing relentlessly on the butt of his cigarette while trying to phrase a question that doesn't openly question her sanity.
"Eh, Robin-chan… you're sure?" He doesn't quite succeed.
A nod of confirmation. "Ah. His nakama were counting on him, after all." Her eyes return to her notebook. "Quite a romantic notion, yes?" It's meant to be rhetorical despite the cook still fumbling for a reply. He at last gives up when it's clear Robin has dismissed him for the world inside her notes, heading back to his kitchen with a peculiar glaze in his stare.
A day later the sniper approaches her, and his face is twisted in puzzlement, eyes nervously scanning the ship for a certain blond cook. He has a plate of cupcakes in his hand. "Neh, Robin, I think these are for you and Nami. You might wanna eat them before Luffy finds out."
She spares one glance at the admittedly delicious treats colored with meticulous decorating, each sugary confection made with painstaking care. Robin smiles at her fellow pirate; a fond, honest one.
"I assure you, Long Nose-kun, they're for you."
