[To begin, there is a blurry image of freckled cheek and ginger hair, which slowly comes into focus as wildly air-dried post-saltwater swim and rather full of sand. Sean is wide-eyed and twitchy and not exactly the most technologically savvy person in the world even when he isn't confused and fighting off panic and entirely uncertain of what this piece of electronics is meant to do, so bear with him as the video blinks in and out.]
