Knee-deep, Crowley pauses, curling his toes in the loose, clouding sand. Eyes closed, he rolls his head from side to side - left to right, slow, with a long breath in and out before he opens his eyes again.

The water's so clear, here.

Head still tilted to one side, he watches the sun filter through the shallows and lay a moving web of light on the rippled sand beneath.

Breathe in; breathe out.

Low and sleek, Crowley dives.
