List of EastEnders characters introduced in 2009

Debra Dean, played by actress Ruth Gemmell, first appears on 5 January 2009. She is the mother of established character Whitney Dean (Shona McGarty), who she left along with Whitney's father, Nathan Dean, when Whitney was very young. Debra kept in touch with Nathan and his partner Bianca Jackson (Patsy Palmer) so Nathan and Bianca could keep her informed about Whitney. Debra is known to have worn a crucifix, which she gave to Whitney before she left. She also gave Whitney a porcelain doll that was broken by Whitney's sister, Tiffany Dean (Maisie Smith).

Debra is first mentioned in late December 2008 when Whitney decides to get in touch, only to discover Debra has not received the letter as Bianca gave her the wrong address. She claims not to have the right address when Whitney asks for it, wanting to protect her, but Janine Butcher (Charlie Brooks) discovers Bianca is lying and steals it from Bianca's address book, and gives it to Whitney.

Debra and Whitney meet on 5 January at a café where Debra works. Whitney tries to discuss when they had lived together but Debra is not interested. She shows no interest in Whitney, coldly rejecting her, upsetting Whitney so much that she breaks down in tears just after she leaves the café. She goes home and tells Bianca that she is her mother as Whitney felt visiting her birth mother was the biggest mistake she has made.

Whitney does not have any further contact with Debra until 5 June when she arrives unexpectedly. Bianca sends her away but Debra returns a few days later, insisting she wants to get to know her daughter. Bianca tells Ricky Butcher (Sid Owen) that Debra is not to be trusted and on Whitney's first birthday, she went on holiday with friends instead of being there for her daughter. Debra takes Whitney out for lunch at The Queen Victoria public house, where they start to bond, and Debra confesses that she is homeless. As a result, Whitney asks Bianca to let her stay with them. Whitney helps her sell some counterfeit DVDs. Their bond grows stronger and she surprises Whitney with her plan to move to Greece and asks if she will come. Whitney delightedly accepts, only to realise that Debra is using her when she leaves suddenly, passing her a sealed envelope and saying she will be back for it, and warning her not to open it or she would be "sorry".

Debra returns on 17 July with cuts on her face, just after Ricky leaves after failing to convince Whitney to go to Brighton with them. Debra says that someone is after her; it turns out to be her son Ryan Malloy (Neil McDermott). Whitney and Debra go to an abandoned school and retrieve a bag. Debra will not let Whitney see the contents and when they get home, a man who has been stalking Whitney is inside. The man is Ryan and he and Debra argue. When Whitney defends her mother, Ryan tells her she is his mother too. It is revealed that the bag contains a knife with which Ryan stabbed somebody. Ryan returns the next morning and argues with Debra again, causing Whitney to run out and throw the knife into the canal. When she returns, Debra plans to leave but when Whitney tells her about her abuser Tony King (Chris Coghill) and his upcoming trial and says she is going to cook them a family meal, she agrees to stay. When Ryan and Debra are alone he tells her to leave, insisting she is a bad mother and that Whitney is better off without her. Looking frightened, Debra leaves. In December, Debra sends Ryan a text message to say that she cannot attend Tony's trial to support Whitney and not to contact her again. Provided by Wikipedia
