Zoro and Sanji's second time. The less said about the first...

The fight is brief and unsatisfying. The whole thing takes no more than five minutes and no more than two swords. They still hum for blood as Zoro sheathes them and faces the gang's growling, pissed off boss. “Fine,” the man shouts. “We’ll take you then, huh? Plenty of folks will pay to bring a big man down low,” he says nonsensically. “What—” A sharp pain in his ankle cuts him off. A downed man pulls a needle out of Zoro's skin.

Three inches in front of Sanji's face, Zoro is wearing an expression that could wither stone. "What the fuck," the swordsman snarls, "do you think you’re doing." The remaining logical dregs of Sanji's brain recognize that he's just gotten himself into a pretty dicey situation. The rest of it apparently doesn't fucking care, though, because the absurd line of response he comes up with is to grin right in Zoro's supremely pissed-off face and say- "Well, what was your dumb ass doing?" In which the crew’s plastered, Zoro needs to blow off some steam, and Sanji gets taught a lesson or two.
