i got a question. when quent starts to think about his family's death, he sees a wolf, if im correct he saw Darcia; but thing that i dont understand is, was it darcia? cause if i put enough atention to the series, darcia couldnt turn into a wolf until he had the stone at the end of the series. can somebody explain that to me?

according to the guards it was jagara's man who killed everyone, so what quent saw was an illusion?
