Potter's Occlumency had gone horribly the next time he came back, and Hermione had taken to brewing during those periods and doing Occlumency with Professor Snape in the other periods. Now that she had finished her Potions recipe for the Warding Potion she had moved onto another idea. This was a potion that would break through all Occlumency barriers and take all knowledge from the drinker's brain, transferring it into that of the person whose hair was put in the potion. It had the same roots as that of her Cruciatus, but it involved a transfer of knowledge. It was extremely complicated and Hermione thought it would take at least a year before she could finish it.
