The sniper could hear the navigator coming before he saw her. Well, he could hear the child she was carrying in her arms crying his lungs out, not Nami, but she was the first thing he spotted. Usopp cocked his brow a little, looking at the pair. Nami was holding onto her patience with the wailing boy, who was rather upset as it was. Once the navigator reached the ship, the child was plopped unceremoniously into the sniper's arms.
"Watch him. I have a migraine, and I don't think I'll be able to stand it without making him more upset," she groaned, rubbing her temples. "I don't even know why he's crying, anymore…" And the red-head was then off without much more of a word about what the boy was doing here or even his name. The kid looked red, terribly so, and was bawling and fussing with all the force his little body had to try and get something.
The crew member felt his hopes to keep working on his weapons on-deck while it was quiet wither up and die. With a calm sigh, the kid was carried down into the men's bunkroom, several small mutters about never having time to himself slipping out. There was always some mischief, some Marines, or an elastic Captain distracting him just long enough that work was hard to get done! Huffing lightly, the sniper forced those aside and set a faint smile on his lips as he glanced the wailing child over. Down here there inside the ship was some nice shade, at least, and the squirming ceased from the boy the second they were within it.
Cocking his brow, Usopp started towards his bunk, anyways. "You tired, little guy?" he murmured, rubbing his back softly. He didn't know why, but the kid just started fussing up a storm, again. He froze, panicking a little and almost turning the boy every which way instead of moving his head to look and see what was up. He rocked and bounced and cooed to the little guy, but nothing worked! He tried lifting up the back of the boy's dirty shirt, and balked at the extremely pale skin he found under it. Come to think of it, they were standing in a patch of sunlight from one of the windows… Finally, something clicked. Two steps backwards and the bawling calmed back down a fraction, again.
"Oh, I get it," the sniper hummed, craning his neck to get a better look at the child's face and grinning. "The light hurting you, little man? Well, never fear! The Great Captain Usopp will save you!" As he struck a small pose, holding the kid gently to himself, the crying stopped very suddenly. Two watery red eyes were just looking at him intently; almost like he'd surprised the kid so much that he didn't know how he should be reacting, now.
With as much fanfare and flourish as he could muster, the sniper fetched some extra sheets and wrapped them around the boy, draping some over his head like a hood. "Now… We need to get something front out there to make you feel all better, okay?" he edged towards the light, feeling the small form suddenly tense up once it noticed. "It's okay… The Great Captain Usopp is here, and such a brave little guy like you can do this, huh?"
The boy sniffled and let out the tiniest of whimpers, tugging the blankets tighter around his face. That was good enough for the sniper, and just to test this a little, he edged into the light, only enough to shine it on the kid. No instant bawling graced his ears, and he gave an encouraging hum before quickly turning and shimmying back on deck. There were complaints from the sunburnt child in his arms, whines and shifts and hidings further into the blankets the majority of it when the sun was back over his head without anything blocking its rays completely.
"I know…" Usopp hummed gently, keeping his pace fast as he moved over the grassy deck, humming and gently rocking the kid to try and keep him relaxed. "We're almost there, now…" The child still didn't seem convinced or pleased. Darting into the sick bay, Usopp snatched up a small tub of ointment and checked it over before hurrying back into the darker bowels of the ship where the kid would be more comfortable.
Hushing the whines with some soothing humming, the pirate got to work, settling the kid down on the chair he had managed to whip up for his workbench down here. He turned on the lamp, but kept it dim to hopefully keep from any more wailing. Slowly, the boy peeked out of the sheets at him, redder than Luffy's usual shirt in this light. Carefully, blanket was separated from boy, something the child didn't seem to like all that much.
"Where's that brave little guy who was out in the sun just a little while ago?" he crooned, the black haired weapons master finally detaching the little fingers from the cloth. "I can't make it stop hurting if I can't see it! The Great Captain Usopp is truly great, but not so magical with making sunburn go away!"
Popping the tub wide open, the sniper scooped out a fair bit onto his fingers and started to rub it into the burnt skin on the child's arm. A soft cry slipped out, and he gently started humming his song about Sogeking to at least try and help the kid pay attention to something other than the sting of being touched. He worked the aloe-smelling stuff all the way up from his fingertips along his arms and into the skin hidden by baggy sleeves to make sure he didn't miss a single spot, using the child's reactions to touch to figure out if he was on normal healthy skin, yet, or not. He dolloped more out to treat the burnt legs and feet, and another hearty scoop for the neck, shoulders, and head. The kid actually seemed to sit still after a while, but there were plenty of scrunched noses and whines when his face was covered with the slimy gunk.
The kid was allowed to huddle back under the blankets after the ointment had a chance to soak in and at least help numb the sting some. Nodding slightly, the pirate pulled out a basket and some old wood that he hadn't found anything to do with. It took a few quick nails and a little fast thinking to keep the kid from slipping away to explore, but he made it work. Usopp threw a tarp that didn't let the sun though onto the structure, nodding to himself when it laid just right.
"Alright, now, little man!" he chuckled, scooping the kid back up, earning a huff and a whine. "I got a great little shady place for you!" he put some extra padding into the bottom of the basket and set the pouting toddler into the little shady spot before picking up the basket. "See? Nice and comfy, and I can get a little work done up in the sun where it's nice and warm. And you can nap!" He booped the little nose before him, chuckling at the tiny giggle he was rewarded with.
The rest of the hour was calm and quiet up on deck. There would occasionally be a chatter or squeak from the boy as he explored the shaded basket and Usopp would keep him the corner of his eye to make sure he was fine as he worked on his newest pop green techniques. Every once and a while, he brought out one of his more entertaining techniques, making fun little things to keep the child happy and in his little basket. Those red eyes had been the size o dinner plates and as excited as most of the crew had been when looking at Franky's newest additions to the ship when the long nosed sniper made a plant pop up that spouted a stream of bubbles right into the shady area so he could play with them instead of just watching. He didn't do anything scary, loud, or sudden enough to frighten back the wails from the albino boy, and after a while, the child was sleeping.
"Nahhh…. That's enough for today!" the sniper hummed, popping his back gently. He glanced over to the boy, smiling gently and scratching his chin. "But what to call you… Can't go around calling you 'little man' all the time, now can I? Until I get your real name, at least..." The pirate thought hard, frowning and tempted to jot down a bunch of names before genius struck. "Yeah… You look like one of those!" he nodded, tucking a blanket around the small body. "Nathenail… That's what I'm calling you."
