Ali is the daughter of Daniel Rey and the stepdaughter of Kristi, as well as the older half-sister of Hunter Rey

Ali was born to Daniel Rey and her unnamed mother who passed away. She lived with her father in San Diego, California in their large, expensive house, and eventually Kristi came and moved in with them. Ali was shown to be a normal and cheerful teenage girl who got along well with her family and was motherly towards her baby brother, Hunter.

On August 26th, 2006, the demon attacks Ali's dog, Abby, Ali and her father take the dog to the vet leaving Kristi with Hunter. When they return the next day, Ali notices the odd change in Kristi's behavior and when she sees the tape of what happened, she begs her father to view it. When he does, they call Martine to come back and help them. Martine tells them that to rid Kristi of the demon they would have to transfer it to another family member, that being Kristi's sister, Katie. Ali disapproves as it is unfair to Katie, but Dan disregards her opinion, saying it is to save Kristi and Hunter.

Three weeks later, Ali leaves on a school trip. When she returns home on October 12th, 2006, she finds the bodies of her father, found with a broken neck on the couch in the living room and her stepmother on the floor upstairs in the nursery with Hunter missing.

After the death of her family, Ali started researching demons and became an occult expert
