Harry attempts to extract Horace Slughorn’s memory concerning Tom Riddle and the Horcruxes, appealing to the old potions master’s affection for his mother.
Jim Broadbent gets the audience’s top lips trembling when he describes his sadness at Lily’s passing: “One spring afternoon I discovered a bowl on my desk,” he begins, “just a few inches of clear water in it. Floating on the surface was a flower petal...as I watched, it sank...just before it reached the bottom, it was transformed, into a fish. It was beautiful magic, wondrous to behold. The flower petal had come from a Lily, your mother. The day I came downstairs, the day the bowl was empty, was the day your mother....I know why you're here...but I can't help you. It would ruin me.” Wonderful stuff.
