Noah Tate (previously Christopher Francis Tate, Jr.) is the son of Charity and Chris Tate. He appeared from 2004 to 2005. He is due to return later in 2009 when his mother returns.
Noah Tate is born in prison while his mother Charity is jailed for the murder of his father Chris, who had actually committed suicide. His paternity was in doubt, as Charity had been sleeping with her cousins Cain and Marlon as well as her husband, but DNA tests confirmed he was Chris' son. Charity then sells Noah to his aunt Zoe, who names him Christopher after her brother. In exchange for this, Zoe tells the court that Chris had set Charity up for his murder and she is freed. The courts, however, do not allow Zoe to adopt Christopher due to her past mental illness and Charity takes him back. She changes his name back to Noah and leaves the village in 2005.
