And Odo the hero, they bore him back home

Who is Odo, why did they bear him back home ?

Odo was a wizard we come to know fro the Harry Potter series of books. Slughorn sang a song about the wizard Odo when Harry and Sluggy were consoling Hagrid over the death of Aragog, the giant spider.

They bore him back home coz he was dead.

Why does this interest us ?

Because it is a clue from the Harry Potter books regarding the death (or actually absence of proof of death) of Albus Percival Wulfric Brian Dumbledore (born ca. 1840s [1])

And Odo the hero, they bore him back home,

To the place that he'd known as a lad,

They laid him to rest with his hat inside out

And his wand snapped in two, which was sad. (HBP pg 488/456)

From the story, we don't see any mention that they snapped Dumbledore's wand in two. After the scene at the top of the tower, Dumbledore's wand is simply never mentioned again.

Is it possible that Dumbledore's wand is missing because Dumbledore still has his wand, still needs his wand, because he's not dead ?

But remember, the absence of proof is not proof of absence.
