Sam and Dean come across changelings in Cicero, Indiana. The activities of the changelings are orchestrated by a "mother" changeling, who disguises herself as an adult woman. The changelings steal children in the neighborhood from their beds at night and then take the real children's places in their family homes. The real children are kept alive, in cages, in the basement of a house abandoned mid-construction, for the "mother" changeling to feed off.
Meanwhile, the child changelings feed off of the human mothers' synovial fluid by suckling with their round, many-toothed mouths at the back of their necks. The changelings take their place in human homes as soon as they are formed, and feed off the mothers until they waste away. Any other humans who come between the changeling child and its prey are murdered. The mother changeling is finally killed by fire (Sam and Dean use a flamethrower). When the mother is killed, the children are destroyed also.
Changelings in Lore
In European folklore and folk belief, a changeling is the offspring of a fairy, troll, elf or other legendary creature that has been secretly left in the place of a human child. The apparent changeling could also be a stock, a glamorized piece of wood that would soon appear to grow sick and die.
