–Auntie Poulet to Tommy Vercetti
The grandfather of Auntie Poulet is only mentioned during the GTA Vice City mission Juju Scramble. He was possibly born in Haiti, but moved to Vice City to live near his grand daughter. The precise location of his shack/home is unknown. He was informed by his grand daughter to Tommy Vercetti. Rumors have been spoken out regarding the exact location of his home and his involvement in Haitian Voodoo Ritual.
Upon analyzing the quote, it can be said that her grandfather may be a soul, however, no physical evidence is present to support this claim, but keeping in view the other quotes, one can certainly be curious about his status. In the following missions, Auntie Poulet speaks to Tommy that many dead men are talking about him. This seems to suggest that being a witch doctor, Auntie Poulet may be talking to the dead including her grandad.
