It was true; Harold was far from the center when the bomb hit. Of course, even if someone was at the furthest perimeter of the blast, they'd change. Harold had heard horror stories of people morphing into cats and lizards over weeks, only to find out that they'd been hit with residue from a blast maybe a mile away. It was only a matter of time.
Upon getting hit, Harold followed the steps he'd overheard on a blaring tv screen while channel-surfing: remove his clothes, get to a safe and sheltered place, and scream out for help. Though it felt weird being naked in in front of such a large crowd, it was necessary in case he grew any limbs such as a tail or wings. And he barely had his underwear off when he noticed the first, and perhaps most jarring change: his penis was absent, replaced with a slit that felt almost decorative than anything, as he (or would it be she?) felt an odd numbness between her legs, as if all sex organs had been stripped from her body. She reels back, only to find out the second change: he was shrinking, and fast.
