"He was a lot of things to me" "The only conclusion was love"
I think people can work magical object without having the spark of magic. Snow, for instance, could open the jail cell by blowing on ink of the parchment. But that didn’t require her to be magical, just to use the magic already present. Same with Belle. All she needed to do was pour the potion into the fairy dust in the town and the magic worked itself.
I also think this is in contrast to Neal in 301. There he had to direct the magic himself. It wouldn’t work if Neal wasn’t focused. It was more than just using a magical object, something inside him also let it happen.
