Victoria made a Deal with the Devil so she can get her own gift and door.
Here the point. First, how come Victoria get a gift and door unlike Felix and Augustin despite being married in the family and not being related to the Madrigals? And second, I highly doubt the Casita will granted a evil person with gift. I found this confusing but I decided to make a theory about this. Victoria knew the Casita wouldn’t accept her in the family because of her evil soul but she desired the gifts from the Madrigals. Shortly before her marriage to Bruno, Victoria use dark arts to summon a devil and made a deal with him to make the Casita accept her into family and be granted a gift after she is married.- Jossed. She happened to go to visit Bruno on the night before Mirabel's gift ceremony. It was pure bad timing that she came across Mirabel's door and (since she's technically a Madrigal) took the magic for herself.
