context: The first episode revolved around Oliver's parents (Agnes Fleming and Edwin Leeford) as they struggled to fight their love for each other. Edwin struggled with his estranged wife Elizabeth Leeford, mother of his son Edward Leeford (later also "Monks"), and Agnes struggled with her family's life. When it came to them both being together, Elizabeth murdered Edwin and planned on murdering Agnes. She made Monks kill her, but Agnes ran away; her sister Rose (Keira Knightley) witnessed this and was left traumatized. Agnes was pregnant with Oliver when she ran away. She ran into the main streets of London and collapsed; she was then taken into the workhouse where she gave birth, and she died shortly after.
  Once he reached nine years of age, Oliver was taken to a different sort of workhouse where he was abused and tortured. The boys of the workhouse pulled straws to decide which of them should try asking for more food; Oliver got the short straw. He was then sold to Mr Sowerberry, after Mr Bumble beat him. Most of Mr Sowerberry's family abused Oliver as well. When Noah Claypole insulted Oliver's mother he lost control and ran away. Monks, who was aware that Oliver was alive, arranged for Fagin to take the boy in and train him as a pick-pocket. Oliver was taken by the Artful Dodger and taken to Fagin. Oliver believed Fagin to be a magician as he knew his name straight away. Monks arrived and began having a fit when Oliver was asleep, shortly after he told Fagin that he wanted Oliver to be disgraced in public.
