William (Zygon: When Being You Just Isn't Enough)

A wealthy person whose first name was William was copied by the Human-Zygon hybrid Lauren Anderson.

The "man" used "his" Visa card to buy clothing at the shop Monsoon for "himself" and the real man. "He" went into "his" Mercedes and drove to "his" house, where "he" was greeted by "his" wife. (HOMEVID: Zygon: When Being You Just Isn't Enough)

Behind the scenes
This man is credited as simply "Wealthy man". However, his I.D. is briefly visible on-screen, during which his first name is clearly legible as "William". Although somewhat hard to decipher, the rest of his name appears to make him a namesake for producer and director Bill Baggs: "William B. Baggs".
