Adrian looked closely and a crop was suddenly growing from the neck of the witch. Since he was not able to see it, Sirius was the one that observed from the shadows. Sirius fed the memories that he had on what happened earlier and Adrian could not believe it himself.
It was not Farmer Vincent that created such an event but one of the blessings that was given to him. When the witch tried to inject some of her mana into the body of Farmer Vincent, the blessing activated, and her spell backfired. Not only did the spell backfire but the blessing of the fae activated to put a natural curse on the witch.
