In the final chapter of La Fiesta del Chivo (The Feast of the Goat), Samson the parrot plays a recurring role. Here are a few examples:
Her reply is a sudden jabbering. The five women turn their heads: Samson is awake and announces it by chattering. [...]
Samson, who has been quiet for awhile, displays his pleasure or displeasure again by puffing out his feathers and shrieking. No one says anything. [...]
Samson has begun to move nervously around the bars of his cage; he sways back and forth, stops, sharpens his beak on his claws.
These short interludes are interspersed in Urania's recounting of her most tightly held secret, but I don't recognize any real pattern. I suppose it's possible that Vargas Llosa simply wanted a light way to interrupt the story, but I suspect it's more than that. What is the purpose and/or meaning of Samson's interjections through this crucial part of the story?
