Yvonne

Yvonne is a witch and Cajun healer who worked as the resident cook and housekeeper at Montague House. She had worked there for decades before Kane Montague and his wife took over. The Charmed Ones suspected her to be evil due to the mysteries surrounding Montague House and her bad attitude. She only appears in the novel, Voodoo Moon.

History
Yvonne had worked at Montague House since she was young and never married nor left the place. The bed-and-breakfast was infamous for its evil purposes and Yvonne did what she could to protect those who came.

In early 2000 during Mardi Gras, the Charmed Ones came to stay at the house. Phoebe Halliwell got curious about the kitchen separate from the rest of the house and tried to enter, but Yvonne stopped her. Unbeknownst to the sisters, Phoebe had been poisoned by the Montagues and was slowly turning into a zombie. Yvonne realized what was happening and stole a lock of her hair to brew a protection spell, but Gabrielle Toussaint was too powerful for her. When the sisters decided to leave abruptly, Yvonne demanded they stay, threatening that things would not end well if they left, but Prue flung her to a wall in an anger response. This caused Yvonne to flee in fear.

Ultimately, Yvonne and Randy came to help rescue the sisters. Piper froze the evil voodooists while Yvonne restored a zombified Phoebe and Gabrielle's innocent sister, Helene. The spell took most of her strength and she nearly fainted. When the freeze power wore off, Yvonne gave the sisters a spell to banish the Petro loa, but it was too strong for their powers. Randy then summoned forth the second Petro loa the voodooists were also worshipping and were punished for it.

Yvonne, Helene and Randy celebrated with the sisters at Remy Fortier's restaurant on their last night. To their surprise, Yvonne knew Remy and was able to reserve a table in no time.
