Carol responds:
Actually, it's clear that Snape's wand didn't switch allegiance. Sirius Black uses it to help Lupin transform Wormtail into a man and to bounce Snape along through the passageway (but, of course, he wasn't involved in the Expelliarmus, so the wand wouldn't have considered switching its allegiance to him--it was just another wizard's wand to him, just as Lupin's dropped wand is just another wizard's wand to Pettigrew, who nevertheless attacks both Ron and Crookshanks with it before Harry disarms him), but when Sirius transforms into a dog, he leaves Snape's wand behind. Snape uses *his own wand* to conjure the stretchers to carry Sirius Black and HRH to the hospital wing. He has no reason to switch to another wand because he wasn't "defeated" in the sense of being permanently disarmed. They were merely attacking him (three on one) to let Lupin continue his story. The wand that chose Snape and built up a relationship with him is not going to switch loyalty to three weaker, inexperienced wizards just because they temporarily disarmed him, IMO.
