Arlene Turling is a young woman in her early twenties. She was raised by Hillary Eastwood, the town's mayor, after her own parents died. Now she is the mayor's secretary, assistant, and the best friend of Evita Eastwood, the mayor's daughter.
When the town was invaded by the beastlords, Arlene was the one to wait for the squad of Brotherhood of Steel. When they came, she informed them of the location of the mayor, and revealed that the key to the successful liberation of the town is deactivating the sirens.
