Luna had wondered with whom she had been placed in a dungeon room, beneath the Malfoy Manor. It took her several days and sharing her rations with him for the elder wizard to trust her enough to speak to her. It was then that Mr. Ollivander told her to abandon all hope of being rescued. The only thing to look forward to in this forsaken place was a speedy death.
She questioned him as to why this was, when there was so much to live for. Even after months of captivity, torturing and malnourishment, her enthusiasm for life wasn't dampered one bit. Sure, she missed her mother… but that didn't make her morbidly depressed and wish that she could join her. In actuality, it was that very same fact that gave her the strength to carry on, even as others fell nearby, months later during the battle for Hogwarts. It gave her strength to use the wand Ollivander had fashioned for her after their rescue. Who would have thought that she could pass on her own zest for life to a man that had given up on everything and everyone in the world?
