The Mathews family can't be the reincarnation of the Kavanaughs. Victor and Henry are still alive. A soul can only occupy one body at a time. And Victor, Henry and Eloise are not a part of the reason for the reincarnation of the initial two parents.

I believe the beginning was in the 1600's, if you notice the clothes on the man nailed to the tree, and the little girl who hides behind the rock, they are definitely colonial. The man from the tree in also seen drinking blood from a skull. These were the parents who sacrificed their children, and I believe that the ritual brought in the man in the yellow suit and his henchman, kimono woman. If this is true, then saving the children can't mean that they're still alive. I think it means saving their souls by finding their bones and burying them in consecrated ground...the church.

I think the sacrifice of the children was done in the 1600's, look at the clothing the man wears who is nailed to the tree. Look at what Tabitha is wearing in the dream she has as a child. The man who was nailed to the tree is also seen drinking blood from a skull. I think the children were killed by their parents, and their blood was taken for the ritual, this is why they are seen as very pale. I think that freeing the children means finding their bones to be buried on consecrated ground, the church grounds. These incarnations of Tabitha's soul has been happening for years, and the puzzle is never solved. And it seems that each incarnation has a brilliant person to help, but isn't utilized, ie. Jade and Christopher, and there could have been others.

I believe only Tabitha is a reincarnation. You can't meet yourself in a current incarnation. I believe this chain of incarnation started in the settlement, it looks like an American colony in the 1600's. That incarnation may be when Tabitha's soul is the only one that can free the children. I believe the children were sacrificed by the parents and Tabitha was the only one to escape. And who said Eloise was dead. Victor never found here. I think they should be looking for the bones of the children to bury on consecrated ground. This will free them. And Fatima is giving birth to a new lord of this underworld.
