Nabu/Riven - Falling asleep together
Nabu was the kind of tired that left an ache in his bones and an itch behind his eyes, the kind of tired so deep that it felt as though he could drop off to sleep and not wake up for an entire week. Which made it all the more infuriating that his brain refused to slow down long enough to let him actually drift off.
The ship was quiet around him, a rare occurrence for their usually boisterous group of friends, but that was merely a testament to the intensity of the mission they'd just completed, leaving them all so tired that even the ones who had managed to stay awake didn't have the energy to talk.
Musa and Layla for instance were curled up together on a seat opposite Nabu, Layla's head tipped back against her girlfriend's shoulder as she dozed while Musa twirled an errant curl around her finger, blinks getting slower and slower. Just down from them, Brandon and Stella were dead to the world despite the hard metal of the bench seat they were stretched out on. Sky, in the pilot's chair up front, had to be awake, and Bloom was perched on the arm, staying awake in solidarity until Sky got them back to Magix. But even despite Sky's idle hand on Bloom's knee, and her tilting sideways to rest her cheek on the top of his head, the pair weren't talking, the exhaustion making it impossible to do much more than yawn and keep the ship from crashing.
Nabu was so busy people watching, eyes drifting lazily from side to side that he almost missed it when Riven tilted from where he had his head tipped back against the wall, snoring quietly, to rest against Nabu's shoulder. But it would be impossible for Nabu not to feel the warmth of Riven's proximity, nor to miss the way his heart jolted.
He supposed he should wake his friend up, Riven was not one to show any sort of outward affection, and would be embarrassed to find himself in such a position when he awoke, but Nabu couldn't make himself. Not when the heavy weight of Riven against him was settling something inside him, and the faint traces of his friends cologne were lulling him too into a gentle slumber.
