Why does everyone's wand still work for them?
With all the questions that have been asked about wands switching allegiance by disarming opponents or physically beating them, wouldn't everyone's wands already be mixed up?
- Snape disarms Lockhart during the dueling club
- Also in the second book, Harry disarms Lockhart
- In the fifth book, all of Dumbledore's Army learned how to disarm by practicing on each other, presumably with a different partner each time
- Lupin disarms Ron, Hermione, and Harry when in the Shrieking Shack
And I'm sure there are more examples that I haven't thought of.
