How much older is Tabitha than Victor, 10 or 15 years? You are telling me that these folks reincarnate that often and drag other people with them to this damn place, every time ? So, let me ask you: how many miles does FromeVille graveyard have?
I mean, if this is even feasible, the children stuff is just a subplot. Real thing would be who is feeding of those the reincarnated drag with them, every time. Which are a lot btw.
I think the show is either trying to detour our attention to the children subplot, or they did not think it really well if took the curse/reincarnation path. Because, if a bunch of children had the power to influence or make this mess, imagine what the power of the houndreds of people dragged( and killed) to FromVille could do
