I like the idea that his heart must be given up willingly. Perhaps they’ll tie that into how PP came to his position as well, because traditionally, it was his choice to stay with the fairies and become who he became. Would it sort of negate the power of the heart of the truest believer if the heart had to be taken by force? Because if it’s taken by force, that means that the owner of it doesn’t want to give it up, doesn’t believe that giving it up is the right thing to do, which means it doesn’t really possess true belief in the cause. So if the heart must be 100% true, I’d think it has to be given freely.
