An intentional breach of politeness
"Escort these strangers to my royal palace, and see that you treat them most politely; for although they are in reality my prisoners, they have been guilty of no intentional wrong and seem to be nice children."

Their isolation, and consequently their purely arbitrary going together, is canceled; a unified developing situation takes its place.
