If you have not read it, go away now.
For the rest of you, Somebody, please try to explain what seems to me to be a glaring plot hole:
- At one point in the action, a weapon is lost at Gringott's. Traded, you might say, to the original owners, and so done by Harry, who was arguably the rightful owner.
- Much later, that self-same weapon is used in the final battle.
