I have a few questions about the Vow and how far I could stretch cannon fact until they're... no longer cannon.
Though it's never said as fact, we see, in HBP, that there is a 'Bonder' who oversees the two making the vow and therein 'binds' it. Do you think that the two making the vow could bind it themselves, or would they have to find someone to do it for them?
Is it said anywhere that failure to keep the vow results in death? Or are the punishments the decision of the two making the vow?
Do you think that, if the magic was sealed by those making the vow, it would somehow lessen the power of the spell? Say two children, not very experienced in magic in general, made a vow--without a Bonder--that they would always wash each others socks () and failure to do so would result in their clothes smelling like socks for the rest of their lives. Do you think that because the magic wasn't sealed by another party (therefore probably making the vow less powerful), instead of their clothes reeking for the rest of their lives, they would just have a sort of... almost indistinguishable smell to them?
Can you understand any of this blubberish?
