List of East Enders Characters (2007) - William Mitchell

William Mitchell, played by Toby Walpole, is the son of Billy (Perry Fenwick) and Honey Mitchell (Emma Barton).

On 20 March 2007, Honey finds out she is pregnant again and tells Pat Evans (Pam St. Clement), but asks her not to tell Billy. Pat persuades Honey to tell him, but he is distant initially. He soon comes round, following a heart to heart, and admits to being concerned, like Honey, that they would love the new baby more than Janet if it did not have Down's Syndrome, which Janet has. Honey reassures him it will not happen. After this, the two agree they want the baby and gradually tell their family. On the due date, Honey is knocked over during an incident at The Queen Victoria involving Jase Dyer (Stephen Lord), Terry Bates (Nicholas Ball) and Terry's gang, and she goes into labour. When the baby is born, it seems that he is stillborn because he is not breathing but he pulls through. Honey wants to name him after his father and feels guilty about being happy that he does not have Down's syndrome.

William leaves Walford with Honey and Janet on 2 September 2008 when Billy lies about giving Jase's money to charity, which led to his death. It is revealed a few days later that they are living with William's grandfather Jack Edwards (Nicky Henson). On 18 September 2008, Janet and William return when Peggy Mitchell (Barbara Windsor) wants a family photo taken. On 25 December 2008, he and Janet return again for Christmas but are not seen on-screen. In April 2009, when it is revealed that William is ill, Billy goes to see him, leaving his family, who are torn apart by the true identity of Danielle Jones (Lauren Crace) and her subsequent death, to see William. William reappears the following month, along with Janet, for Billy's 50th birthday party. In May 2010, Billy has trouble telling William and Janet that Honey has been involved in a car crash and that Jack has died. He appears in May 2011 when he meets Billy's girlfriend Julie Perkins (Cathy Murphy) for the first time as they play in the local park. In June, he visits Billy on Father's Day, and in July, William and Janet meet their niece Lola Pearce (Danielle Harold) off-screen for the first time.

In July 2012, William and Janet make an appearance in the spin-off episode Billy's Olympic Nightmare. During the live segment at the end of the second episode of 23 July 2012, William returns to the Square to watch his father take part in the Olympic Torch relay.
