Olivia Zabini was only four months old when she was kidnapped by Alaric Vane, her brother Blaise Zabini, the most dangerous Slytherin at Hogwarts, never stopped hoping she would return.Her parents searched but assumed the worst after coming up empty handed after 6 years..they were devastated.Alaric Vane was a Ministry official that lost his job because of their father and wanted revenge..so he kidnapped baby Olivia and raised her in filth. When Olivia was 3yrs old Alaric started subjecting her to the Cruciatus Curse..he tortured her every day until she turned 11 and escaped. Olivia was the size of a 6 year old due to malnutrition, her growth had been stunted.Olivia has a photographic memory-she remembers everything and can use wandless and wordless magic flawlessly, she taught herself so that she could extract her memories of the torture that she keeps in hundreds of labled vials in a velvet box so she would have evidence.Olivia walked for one week until she found the station and slipped onto the train.Now, finally at Hogwarts nobody knows who this filthy tiny girl is but her eyes and hair, exactly like Mattheo's, are unmistakable.Olivia is a master of Potions though it's because of her memory and her insanely steady hands as she has never made a potion before.She owns no wand. Blaise is 13.Olivia passes out after Blaise finds her and he watches a memory while she's unconscious.
