fun s4 detail is that it’s a mutual veiling on jon and elias’s parts. jon is forbidden from seeing elias and elias cannot be a witness to any of jon’s marks either because 1) the slaughter mark takes place deep within the tunnels, at the very least he had some trouble looking 2) flesh within the domain of the spiral 3) buried is inside the coffin 4) “Ny-Ålesund is a stronghold of the Dark, meaning I can’t see inside.” 5) no reason to believe his sight extends to the lonely either. all in clear contrast to jon’s s1-s3 marks which happen out in the open and within his sight. like. it was their divorce era.
