Will had already expected that answer. It was only natural for a Horcrux to fetch benefits like these.
If Nicolas Flamel were still alive, Will might even have been able to study Alchemy under him in person.
The legendary alchemist had not taught anyone personally in years, but he would still have done Dumbledore a favor.
What a shame. I should have gone to Nicolas Flamel in my first or second year.
Still, it was not too late. If Will improved a little more, perhaps he could undertake Time Travel over the long term once he received the Response of Magic.

"Within a week," Dumbledore said after a moment's thought. "I have a great deal to deal with lately."
Dumbledore had a headache. Even with Lupin and Minerva helping him, there were still plenty of matters he had to handle himself.
