Harry Links Dumbledore to the Hallows

Harry remembers that Albus Dumbledore had borrowed his Invisibility Cloak the night his parents died. He becomes convinced that Dumbledore suspected the cloak was the third Hallow. This revelation leads Harry to believe that he is a descendant of Ignotus Peverell, the third brother from the tale, and that he is destined to unite the Hallows.
