We are all thinking that Abby is meant to be alive with her "sibling" but this implies, that it is all being done with her to be the last one alive, suffer, and then die herself...Have been watching past episodes and it seems to me that there could be many different endings....what if Abby is the killer??? The fortune teller also told Trish "the person who betrays you is also your savior" and she implied it was a male...Is she Wakefields daughter?
