In 2004, Mike's son Danny (Bradley Walsh), Danny's wife, Frankie (Debra Stephenson), and their sons, Jamie (Rupert Hill) and Warren (Danny Young), came to live in Weatherfield, where Danny helped Mike run the factory. Many long-time viewers did not like the addition of Danny and Frankie to the cast, as their existence had only been made possible by continuity error; Mike had long been portrayed as an only child and, adding confusion, Mike's father was also named Frankie. In late October 2005, it is discovered that Danny is actually Mike's son, a result of a fling between Mike and his sister-in-law, Viv (Patricia Brake).
