hatching within Smiler

Smiler's throat convulsed. Then his lips moved and spewed forth not words, but blue-shimmering larvae the size of men's fingers- dozens of them, gouting up to flop onto the wood, and writhe  on vestigial legs toward the man who had just approached. Blood sprayed from Smiler's lips and throat together as the entire substance of his body seemed to convulse and give way to pass more of the things that had just hatched within his living flesh.
