Hermione sat in potions on Monday and watched once again as Harry used the Half Blood Prince's book to best her. She spent the whole hour frantically separating her potion ingredients in accordance with Golpalotts third law to find the antidote. Harry simply sat there for the entirety of the class, pulling a Bezor from his kit when Slughorn came round to check on their progress. It infuriated her to no end, however, it did seem to put Slughorn in Harry’s good books which Hermione supposed was a good thing since he needed to extract a delicate memory from the old potions master.
