Harry saw, in his mind’s eye, the expression on Hermione’s face if she ever heard about this abuse of house-elves, and decided never to mention it to her.
“One for Harry…” said Slughorn, dividing a second bottle between two mugs, “…and one for me. Well”—he raised his mug high—“to Aragog.”
“Aragog,” said Harry and Hagrid together. Both Slughorn and Hagrid drank deeply. Harry, however, with the way ahead illuminated for him by Felix Felicis, knew that he must not drink, so he merely pretended to take a gulp and then set the mug back on the table before him.
“I had him from an egg, yeh know,” said Hagrid morosely. “Tiny little thing he was when he hatched. ’Bout the size of a Pekingese…”
“Sweet,” said Slughorn.
“Used ter keep him in a cupboard up at the school until… well…”
Hagrid’s face darkened and Harry knew why: Tom Riddle had contrived to have Hagrid thrown out of school, blamed for opening the Chamber of Secrets. Slughorn, however, did not seem to be listening; he was looking up at the ceiling, from which a number of brass pots hung, and also a long, silky skein of bright white hair.
“That’s not unicorn hair, Hagrid?”
“Oh, yeah,” said Hagrid indifferently. “Gets pulled out of their tails, they catch it on branches an’ stuff in the forest, yeh know…”
“But my dear chap, do you know how much that’s worth?”
“I use it fer bindin’ on bandages an stuff if a creature gets injured,” said Hagrid, shrugging. “It’s dead useful… very strong.”
Slughorn took another deep draught from his mug, his eyes moving carefully around the cabin now, looking, Harry knew, for more treasures that he might be able to convert into a plentiful supply of oak-matured mead, crystallized pineapple, and velvet smoking jackets. He refilled Hagrid’s mug and his own, and questioned him about the creatures that lived in the forest these days and how Hagrid was able to look after them all. Hagrid, becoming expansive under the influence of the drink and Slughorn’s flattering interest, stopped mopping his eyes and entered happily into a long explanation of bowtruckle husbandry.
The Felix Felicis gave Harry a little nudge at this point, and he noticed that the supply of drink that Slughorn had brought was running out fast. Harry had not yet managed to bring off the Refilling Charm without saying the incantation aloud, but the idea that he might not be able to do it tonight was laughable: Indeed, Harry grinned to himself as, unnoticed by either Hagrid or Slughorn (now swapping tales of the illegal trade in dragon eggs) he pointed his wand under the table at the emptying bottles and they immediately began to refill.
