No desperate banging of the trapped and drowning came from the torpedo tube, so either Daisy had already accepted her inevitable expiry or all had gone well. It was another thirty seconds before an actual sign came; Daisy's voice, from the navigation deck, through a weak signaled communicator that was more interference than words as she swam further away from the hull; "Warn me if you see any sharks."
Out in the clear water, lips tasting of salt in the mask she had strapped on after retrieving it from her bag in the dark of the torpedo tube. It let her breath the air from the tiny, single-serving pocket she could carry with her and keep in touch with the crew on the sub, if they cared to pay attention. All she really needed that for was to make sure they didn't leave her stranded out here in the middle of the ocean. Ahead, she could see the white sand stretch on and slowly rise towards the surface, and the beaches of the lush island. This early, there was barely a breeze to rustle the palm leaves, and only a crab scuttled across the wet sand as the tide pulled back. As the sand caved inward, rushing down into a pit far below where the stone had collapsed leaving a hole to be filled, the crab fell, too, flailing against the falling, abrasive grains and crushed under their weight. A wave crashed to the shore, filling the hole, flowing upwards and following the neat path newly created as tunnels below collapsed all the way up the beach and into the green forest, heading for the mansion above. The tide drew back, but the trees continued to collapse, and the whole island shook as its underground impacted.
Far out into the ocean, under the glinting caps of the waves and down where the light should have been constantly dispersed, a strange, white, pinpoint glow slowly faded and the churning column of bubbles hissed and floated away to the surface. Daisy let her arms relax and float in the gently rolling water, wondering if that did anything like it was supposed to.
