    Summary

    Sans is used to frolicking at the ocean's surface, it's where mermaids live after all: riding in ships' wakes, breaching the surface, diving down to the sandy bottom, sitting atop rocky outcroppings and luring in ships with their siren songs, playing with the dolphins, those sorts of things.

    Too bad he gets injured and caught up in a current that drags him down to the dark depths of the ocean, where there's so little sunlight it's a murky twilight at its brightest. Thank goodness the Fell brothers found him instead of something more dangerous. Now the pair has to nurse him back to health before the heavy depths crush the delicate little surface fish.
