pearl and cleo have fundamentaly changed after limited life, pearl found a family to fight for, finally laying dawn the title of lone wolf while cleo, who maybe hasn't changed much personality wise, has turned human, very clearly flesh and bone since last episode
lizzie in secret life, is an outsider, almost like she's taken over pearl's curse of loneliness, gem on the other hand thrives as a zombie, or so it seems at the surface, only time will tell if the massacre was worth its price
so maybe the body and soul imprint on each other, maybe you can't split the two exactly without leaving bits and pieces disarranged, maybe lizzie and gem took pearl and cleo's defining traits after limited life
maybe months from now, when everyone has forgotten about zombies and betrayal, rendog will awaken with an unfamiliar fury consuming him from the inside out
