I can see it now.
Seb just told Sam to kick sand all over Alex's legs because they're covered in Eggs. Elliot overheard and just walked away at the shenanigans that kids today play, though secretly he's taking mental notes of everyone's reactions for his current book. Shane is blissfully unaware and is about to receive a glancing douse of beach sand from Alex as he retaliates, but hey, at least he won't get any in his eyes. And Harvey is there to save the day. But how, you ask?
He will blind all within a 60 meter radius into whimpering submission by the dazzling brilliance of his never-tanned indoor-Doctor's chest. Even Shane's theoretically well-protected eyes will experience flash blindness, merely recovering a few seconds quicker than the others to crawl back to the changing hut vowing never to leave home without protective Chickens again.
