This totally could've gone into And on and on we go, but I'm hoping to add at least two more parts to this. It (sorta) has a plot to it, but this is kinda the intro to it all.
It happened the moment Sanji took his eyes off his captain. One minute Luffy was climbing the ladder to board Iceburg's ship, the next, Sanji was holding onto the back of his vest, barely saving the unconscious rubber-brained idiot from taking an unplanned dip in the ocean.
Franky, who had climbed ahead of the both of them, peered of the railing, probably hearing the grunt Sanji let slip out as he caught him—and it wasn't that Luffy was heavy. On the contrary, Luffy's rubbed body weighed very little compared to that of a normal human being, but the whole thing had been just so unexpected that it had taken all of Sanji's reflexes to catch the falling boy.
"What happened?" Franky asked, catching sigh of Luffy dangling above the open ocean.
Sanji let out a large exhale. "It started raining idiots," the cook muttered, hefting Luffy up to get a better grip on him. Franky had to help him, but eventually, Sanji got Luffy to the deck with minimal hassle, and Luffy didn't even stir the entire time.
Chopper came rushing over (Robin carried him and set him down next to Luffy, actually, but Chopper was pretty frantic at the sight of him) and immediately began to check him over, fussing over him the way only the Straw Hat doctor could—with snot, tears, and extreme care and precision.
Sanji took a drag from his cigarette. "He doing alright?" the cook asked, because this was Luffy, and as much of a moron as the little shit could be, he was still the man Sanji'd chosen to follow out to sea. There was no way he wouldn't be worried. Especially after just collapsing like that.
Then again, Luffy wasn't the type to keel over until he had done everything he wanted to do, which apparently wasn't boarding Iceberg's ship since he lost consciousness halfway up, but Sanji definitely gave him points for staying awake this long. Out of the entire crew, it had been Luffy who'd sustained the most damage.
"With injuries like that, could you truly call this a win against Lucci?" Iceburg finally asked after several moments of uncharacteristic silence from the Straw Hats—Usopp wasn't on the deck, but after the bridge they just burned, Sanji would've been more surprised if he was. Iceberg continued, "From what I'm told, they basically beat each other until neither could move. How is that a win?"
The moss head was the first to bark a laugh from where he was leaning against the railing. "Oh, it was a win alright. The only real goal was to get Robin back, and we got her back. So mission accomplished."
"I'm so glad." Nami was still crying, silent tears streaming down her cheeks, shoulders shaking. As much as Sanji wished he could go over there and comfort her, the navigator was holding onto Robin's sleeve—for support or in fear of losing her again, Sanji didn't know—and there was no way in hell he was going to tear her away. "I'm so, so glad we got you back. Welcome back."
Robin just smiled. A genuine smile that Sanji honestly could not remember ever seeing on her face before. It almost mirrored one of Luffy's bright grins that caused blindness if directly looked at for more than ten seconds.
So Sanji looked away, eyes traveling back to his captain and Chopper, who had just finished mummifying Luffy was starting to pack away his medical supplies.
"What's the word, Chopper?" Sanji asked after another puff of his cigarette. "Good or bad?"
Chopper looked…not bad, but thoughtful, like he was trying to figure something out, and honestly, that had Sanji more on edge than anything. The last thing they needed was something else added to their full plates. Sanji was about done with Luffy throwing curveballs in their faces for the day. And the kid wasn't even conscious.
"Chopper? What is it?" Zoro stepped in when the reindeer was silent a beat too long. "What's wrong with him?"
Sighing, Chopper looked up at all of them. "He's exhausted, and slightly emaciated by the looks of it. His blood sugar's dangerously low, he's dehydrated, and he's lost a lot of blood. I've cleaned the wounds out to avoid infection, and all I think he really needs at this point is lots of rest, water, and food to restore his energy."
"I'm sensing a 'but'," Sanji said. "Is there something else that's wrong with him?"
"It's hard to explain," Chopper murmured. "But it's nothing I can figure out for sure unless I ask him directly, though. And nothing I can treat by anything other than prevention."
Zoro sighed. "Well, in any case, we better start preparing ourselves. You know what's going to happen once he wakes up, right?"
Sanji and Nami groaned at the same time that Robin and Chopper giggled.
"Party!" Chopper yelled enthusiastically, Luffy puzzle seemingly gone from his mind. He turned to Sanji, eyes bright and enthusiastic, and the chef couldn't help but let his expression soften just a touch. "Sanji! Sanji! Can you make some amazing party food! Good food is just what the doctor order for everyone to get better!"
"Only as soon as the shitty captain wakes up from his nap." Sanji chuckled. "But I suppose that I could whip up something of a breakfast for everyone else when we get back to the hotel. How does that sound?"
Chopper cheered and Sanji felt his face stretch into a grin. Sometimes, moments like this were his favorite. As long as his crew enjoyed his food and let it fill their bellies, Sanji's day was made.
