Death. Xenophilius secretly summons the Death Eaters, hoping to exchange Harry for a kidnapped Luna. The three escape, but Snatchers capture them. During a vision, Harry sees an elderly Grindelwald telling Voldemort that the Elder Wand is buried with Dumbledore. At Malfoy Manor, Bellatrix Lestrange sees a Snatcher has Gryffindor's sword that she believed was in her Gringotts vault. Harry and Ron are locked into the cellar where they encounter Luna, Ollivander, and Griphook. Upstairs, Bellatrix tortures Hermione. Harry begs for help using a mirror shard in which he believes he glimpsed Dumbledore; Dobby appears in response and helps save everyone while Harry grabs their captured wands from Draco Malfoy. As they disapparate, Bellatrix throws a knife, killing Dobby. Harry buries him near Bill and Fleur's seaside cottage, an Order safe house.
