Christmas Visit to Godric's Hollow
[Harry] - in [Voldemort]'s consciousness - is transported back into a memory of Halloween, . There he walks the streets of [Godric's Hollow], finds the [Potter cottage], kills [James] and then [Lily Potter], and is destroyed when he tries to kill Harry as well. Then, as Harry returns to consciousness, he watches Voldemort - now today - discover a picture on the floor of the [Bagshot house], a picture of the mysterious thief.
Back to Wondering and Wandering
[Harry] awakens, regaining his own consciousness, and finds [Hermione] worrying about him. He then explains to her how [Bathilda Bagshot] was actually [Nagini], remembering [Lupin]'s quote about encountering "magic we'd never imagined." He also learns from a reluctant Hermione that his [wand] has been broken, and feeling like a part of him has been killed, he borrrows her wand to take watch.
As dawn arrives [Harry] laments the loss of his [wand] and sits, irate, thinking of [Dumbledore] and the quest he set them on, seeming more and more futile as time goes on.
[Hermione] arrives with tea for [Harry], as well as a copy of [The Life and Lies of Albus Dumbledore], taken from [Bathilda Bagshot]'s house. Harry honestly tells Hermione that he's not angry with her, but grateful that despite breaking his [wand], she saved his life.
[Harry] is soon distracted by the [Dumbledore] biography - wherein he finds a picture of [Gellert Grindelwald], as well as the story of Dumbledore's family, his onetime friendship with Grindelwald, the death of his mother and sister, and astonishingly, a letter from Dumbledore describing wizarding dominance as being "for the greater good."
[Hermione] and [Harry] wonder aloud about the things they've newly learned about [Dumbledore] - especially given [Rita Skeeter] being the source from which they came. The conversation ends with Harry more furious at Dumbledore than ever, as well as frustrated, wondering what to believe and what on earth to do now.
[Harry] and [Hermione] spend a sleepless night keeping watch in the cold, thinking that they are seeing and hearing someone beyond the boundaries of their protection. They decide, though, to [Apparate] away hidden under the [Invisibility Cloak], and Hermione takes them to the [Forest of Dean].
Nighttime Encounters in the Forest of Dean
[Harry] sits out keeping watch in the dark, still hearing noises around him. Suddenly he sees a silvery doe - a [Patronus] - and feeling it's somehow safe and good, he follows it through the forest until it vanishes by a frozen pool, with the [sword of Gryffindor] at the bottom.
Needing and wanting the sword, [Harry] dives for the bottom of the pool, when suddenly the [Horcrux] around his neck tightens, strangling him, and he is saved only when unknown arms reach around him and pull him to the surface as he blacks out.
Coming to, [Harry] is surprised to discover that [Ron] was the one to pull him from the pool. Ron quickly tells Harry how he found him, and as they wonder about the [Horcrux], Harry realizes that Ron needs to be the one to destroy it. Finally he convinces Ron to do it, and they prepare to do so.
