Harry Potter and the Deathly Hallows · The shard, then the Hog’s Head
A fragment of the mirror shows a blue eye. Harry thinks it might be Dumbledore. It is Aberforth, who has the other mirror. The shard is how he knows when to send Dobby to Malfoy Manor, and how he sees Harry in the passage behind Ariana’s portrait.
