So, regarding wandlore. . . could Harry Potter have given Draco Malfoy Draco's hawthorn wand back to Draco without the allegiance of the Elder Wand switching from Harry to Draco?
We know that Draco Malfoy became master of the Elder Wand when he disarmed Dumbledore on the Astronomy Tower in Half-Blood Prince. Subsequently, Harry became master of the Elder Wand when he defeated Draco by physically taking Draco's wand from Draco while the trio was being held captive at Malfoy Manor in Deathly Hallows. Because Harry wrestled Draco's hawthorn wand from Draco, the hawthorn wand switched its allegiance from Draco to Harry, and the Elder Wand followed suit, for if one disarms another witch or wizard, one masters ALL wands that witch or wizard controls. From Deathly Hallows, pages 493 - 499, US Hardcover, the following information is given regarding wandlore and wand allegiance:
- In general, where a wand has been won its allegiance will change.
- Wands may be at least partially sentient: "The wand chooses the wizard." (Please see my thoughts on whether a wand is at least partially sentient here)
- A person can still use a wand that hasn't chosen them to channel magic, although it may not yield the best possible results.
- Subtle laws govern wand ownership, but a conquered wand will usually bend its will to its new master.
- A conquered wand will better do a witch or wizard's bidding than another wand.
- It is not necessary to kill the previous wand owner to take true possession of a typical wand.
- Ollivander is unsure whether the allegiance of the Elder Wand must pass to its new master through murder.
Given this, would Harry have been able to gift the hawthorn wand back to Draco without the allegiance of the Elder Wand switching back to Draco as well? Or would the allegiance of the Elder Wand switch to Draco regardless of how Draco regained ownership of his original hawthorn wand?
