How does Orson Scott Card use imagery in Xenocide?

Imagery:

"Because the spirit is of the earth, it is that part which makes new things out of old ones. The husband longs for all the unfinished things that he and his wife were making when she died, and all the unstarted dreams of what they would have made if she had lived. Thus a man grows angry at his wife for being too much like him and not enough like his dead wife. Thus a man hates the house they lived in together, because either he does not change it, so that it is as dead as his wife, or because he does change it, so that it is no longer half of her making."

"Each bugger was just another of the hive queen's organs of action and sensation. In a sense the hive queen was already present with them—was present wherever one of her works or drones might be, even hundreds of lightyears away."
