Swiftcurrent Creek BWP · in a past life

His brother's presence is often the only thing that soothes him — so when Helios isn't around, it is sometimes a bit of a crisis for Zephyr. He typically tries to busy himself with other things, too full of pride to seek his sibling even when it feels as if the crawling anxiety will eat him alive. But today, his skin feels on fire and his chest feels tight in a way he has seldom experienced before, and even watching the sparkling rush of the creek does little to calm him.
So he sets off in search of Helios, finally deciding to cave only moments before the earth begins to rumble beneath his paws. He thinks little of it at first, assuming it is the same as the phantom noises he's heard since birth. Then he hears Helios's panicked call, and forgets the rumbling entirely. His stomach flips at the sound, and he breaks into a run. Immediately he assumes the worst: his brother is in danger, hurt — some stranger is surely tearing him apart at the borders now, killing him —
He almost forgets to stop again when he sees Helios, disoriented by the pounding in his ears and distracted by his search for the threat. But he's become better about these things with time, and he does remember to stop, albeit belatedly. Helios! It slips out breathlessly a half-beat before their collision — a softer collision than the last, but he nonetheless tumbles onto his brother in a clumsy tangle of limbs. There is no vicious stranger, no threat, though it takes several moments for this to register fully. When it does, he rolls off of his brother with a huff, glaring at him now. What's wrong with you?
