Charles "Charlie" Woo was the father of Lucy and Michael Woo. He owned an electronics shop in San Francisco. Like many, Woo was puzzled by the new electronics shop Curious Notions, especially because he could not understand the technology. Woo found his life linked to Curious Notions when the proprietor, Lawrence Gomes, named Woo as a supplier of the store's merchandise to the Germany authorities. Woo was taken into custody, but the actions of his daughter and Paul Gomes saw to his release. Woo then did his best to keep his head down and avoid the attention of the Feldgendarmerie.
