Demi Miller arrived in Walford at the age of 13, and immediately became the talk of the Square due to her pregnancy. Feisty and troublesome, she loved to cause trouble with her twin brother Darren. The duo regularly truanted from school, and at one time even broke into the Slater house, scaring Garry. When it was revealed that Keith Miller was illiterate, Demi found it difficult to trust him alone with Aleesha. She tried to drop out of school in April 2005 to take on full responsibility for Aleesha.
