Caspian didn't speak, stayed carefully composed as Keir expressed his confusion about his state of existence. After all, not all fairy spirits belonged to a court, those being the solitary fae. And, not all kelpie would have to be regarded as fairy. He didn't have the slightest notion about the specifics of Keir's being, so there was still the possibility that, though they were both Kelpie, that they weren't half as similar as Caspian had first assumed.
But Keir was still busy scratching him idly, and while he didn't quite have to think about it, it was making Caspian want to lay down and close his eyes. Not to mention, with every pulse that Keir's body had, he wanted more and more to act out on instinct and find the nearest pool of water to promptly end Keir's life in.
Luckily, he couldn't do that, but at least those instincts would assist him in finding the environment they both so seeked. "You're right..." He trailed, allowing the topic of the courts and his servitude drop with the fullest intentions of never revisiting. Instead, the dark horse bowed his body down until his nose was hovering a mere inch above the ground, neck sloped low and front joints buckled nearly in half. It was as if he hadn't a care in the world about his rider, and frankly, he just supposed that Keir would lean back and dig in lest he face being tumbled off Caspian's head. After sniffing the ground more like a dog than a horse ever would, Caspian bolted upright, swiveled his head about a bit frantically, altered his trajectory by about 20 degrees west, and flew. As if his haunches had been wound back like springs, he barreled off the packed sand of the desert and continued on at the same pace he had been before he'd come across Keir, racing across the landscape like a bat out of hell.
It occurred to him that, while his thick kelpie skin might have deflected the grains of sand easily, Keir might not be fairing as well. So, with one dozy of a spin around, Caspian whipped his tail up and over his back, effectively pelting Keir with it in such a fashion as it would flop wetly into his lap. Given it's permanently-dripping qualities, it had the potential to shield his rider at least somewhat from the sand. "You can use it as a shroud, if you wish." The stallion stated inappropriately, well-knowing that he was about two seconds too late to have informed Keir of that option.
But, he was still sore about having his hair pulled and well... that ought to do it, for now. "Up ahead, do you smell it?"
(( It's water. xD Dunno if Keir can smell water. And ditto about the sorry! This post is rusheddd, trying to close up the time between them running pointlessly through a desert anddd playing in an oasissss! x3 ))
