3 - Mrs Lovegood.
"Luna, can you go and check on the potion? There's a good girl."
As Luna wandered back through the house to her mother's workshop, the faint smell of a potion gone wrong filled the room and made the slight 9-year-old dizzy. She stumbled, something which did not escape her mother's notice; Mrs Lovegood ran towards her and saw the smoke fill the doorway. She lifted her wand and said "This should fix it!"... Of course, that was the last thing Luna ever heard her mother say again. She saw a jet of purple light hit the cauldron, but instead of dissipating, the smoke grew thicker in the ensuing explosion. The jet ricocheted off the many pieces of shrapnel, finally hitting her mother in the chest while Luna cowered in a corner.
She never forgot the look on her father's face when he came home from work that day. She vowed never to cause such anguish to her own husband, but did not forget her mother's wish that she should live true to herself.
