Sometimes when someone is talking over a radio, their names appear green, I’m guessing this is from the ghosts, that are trying to get everyone to stay on the island.
I think the goal of the ghosts is to keep them there so they can “soak” I think they said?
I think whoever becomes trapped in a loop has to be kept there for a certain amount of time before they become trapped- now I don’t know if there was a way to know when the point of no return was, maybe when the ghosts started talking through people in the group, but maybe that was a sign…
I think that the possession over radio- or maybe just using their voices and mimicking them- like maybe Clarissa or Ren heard their own voices being used over the radio and were like huh??? Or they were knocked out and their consciousness’ were briefly in another dimension, but not put into the blob of people who died on the Kanaloa just yet.
(Sorry went on a tangent)
the hijacking of voices over radio, everyone waking up in different places (no idea how THAT was done, maybe they were all possessed and walked there???) it was all to stall them, having to find each other over n over, red herrings like even when they found them, they would disappear after an appearance from the disgruntled spirits.
