Usopp is just as beat as everyone else. Running away from everything that Sanji'd summoned with his incessant shouting and calling out for Robin and Nami has been more draining then anything he's experienced in a while. 'Well, at least Nami was safe now,' he guesses. 'That's kind of a relief, especially after watching that jerk take off with her and drop the Sunny out of the sky like that. Though, she certainly doesn't look any worse for wear.'
He watches as Nami relents to their captain's orders and walks into the small villagers' house. Everyone seems to be taking advantage of the moment and catching some sleep while they can. Usopp's all but ready to join them. He walks over to a fence post and collapses somewhere close to it. Sleep, sleep is nice, even if it is on plain, dry earth with nothing really comfortable about it. He doesn't have to worry about anything attacking him in his sleep for now, so he's fine with it.
On the edge of sleep and ready to completely nod off, Usopp feels something jostle behind him. He lazily rolls his head to look over his shoulder and witnesses Sanji moving in and huddling against his back, shifting thoughtfully like he's trying not to disturb him. When he notices that Usopp's watching him, Sanji smiles sleepily. "Sorry, did I wake you?"
"Hmm, not really," Usopp hums. He turns his head back and tries to get back to sleep. While Sanji's presence behind him is reassuring and cozy, he hopes the cooks's too tired to make that comment about not being attacked in his sleep untrue. 'Heh, maybe later, when this is all over.'
As sleep starts to tug his mind away from awakeland again, Usopp's at least aware enough to notice Sanji lifting his head slightly, finding soft fabric replacing the lumpy dry soil when it was returned to a semi-solid surface again, warmth rising from inside it. Usopp smiles as his eyelids finally close completely. 'Sanji's such a hopeless romantic,' he ruminates. Usopp snuggles the arm under his head and silently appreciates it for all it's worth.
