Since the connections between Harry and Voldemort's wands causes very extraordinary behavior when they are met in a duel; Voldemort tries to find a way to overcome the Priori Incantatum phenomenon. Hence In the Deathly Hallows he borrows (emphasized since that is the center of my question) Lucius Malfoy's wand:
“As I was saying,” continued Voldemort, looking again at the tense faces of his followers, “I understand better now. I shall need, for instance, to borrow a wand from one of you before I go to kill Potter.” ...
“My Lord?” “Your wand, Lucius. I require your wand.” “I...” Malfoy glanced sideways at his wife. She was staring straight ahead, quite as pale as he was, her long blonde hair hanging down her back, but beneath the table her slim ﬁngers closed brieﬂy on his wrist. At her touch, Malfoy put his hand into his robes, withdrew a wand, and passed it along to Voldemort, who held it up in from of his red eyes, examining it closely.
-Harry Potter and the Deathly Hallows, Chapter One (The Dark Lord Ascending).
Although Lucius gives the wand to Voldemort, he does not seem to be doing it willingly. There is a lot of mystery behind wands and their obedience to their masters. The Elder Wand being a major example. I was wondering whether Voldemort could expect Lucius' wand to serve him best when he did not defeat or kill Lucius himself. Obviously this attempt did not work, as we can ascertain from the discussion between Ollivander and Voldemort:
“I swear I did not....I believed a different wand would work....” “Explain, then, what happened. Lucius’s wand is destroyed!” “I cannot understand....The connection...exists only...between your two wands....”
-Harry Potter and the Deathly Hallows, Chapter Five (Fallen Warrior).
Later in the book Ollivander explains some things about wandlore to Harry:
- Wands can change allegiance when the owner is defeated
Wands perform better when the allegiance exists
“—then it may be yours. Of course, the manner of taking matters. Much also depends upon the wand itself. In general, however, where a wand has been won, its allegiance will change."
[Details of which can be found in The Deathly Hallows, Chapter Twenty-Four (The Wandmaker)]
As I understand it, Ollivander made a guess, partially scared of what the consequences might be, whether the borrowed wand would work or not. So far I have come up with:
- Voldemort might have thought it does not matter, because his powers were so great, that the wand would merely be a tool.
- Although Lucius did not hand the wand willingly, it is without any doubt that he was scared of Voldemort - possible being "defeated" this way, without any physical/magical fight.
- Lucius' wand itself recognised a greater, more powerful wizard and therefore chose to obey his orders.
- Voldemort did not think of this, and although it might create a slight difference Harry's wand would probably still be able to defend him.
Did Voldemort defeat or overpower Lucius - even though he did not physically fight him - and therefore mastered Lucius' wand?
