 Why did the narrator decide not to mention the Volplas during Guy's broadcast?
Yet I had always been so sure I could create them that I had been calling them volplas for ten years. I had called them volplas since the day old Nijinsky's elongated arms and his cousin's lateral skin folds had given me the idea of a flying mutant. Again in the laboratory, I entered the metabolic accelerator and withdrew the intravenous needles from my first volplas. Meanwhile, it was clear that here was no war of dominant mutations. Suddenly, as I teased the male volpla, this happened. There would be volpla colonies all up and down the Coast before anyone suspected. Volpla wisdom would become a cult—and of all forms of comedy, cults, I think, are the funniest.
 He wanted to keep the secret long term and it wouldn't have been worth it to give it away
 Nobody could hear him over the broadcast's high volume  He wanted to make sure Guy had his moment and didn't want to steal the spotlight  He wanted to brag to Guy later, when he showed him the Volplas in the lab afterwards for a more dramatic effect  He wanted to keep the secret long term and it wouldn't have been worth it to give it away
