This would be interesting if it wasn't absurd. ( I know this isn't your theory, so no shade cast your way)
Under this thought pattern,
BG is only a delivery boy for the Odinists?
He takes them to a vehicle or to the....help me out here,... to a place nearby. Then, later that night, in the cover of complete darkness, with nothing lighting their way, a ritual was performed by sacrificing 2 white girls, again in complete darkness.
One of the Odinists redressed AW, again in darkness, and manually operates Libby's iPhone.
Then, this group is able to disappear and resume whatever their normal daily activities are, unnoticed by their contemporaries.
Is there any established link between RA and the Heathen group? I have not heard of a connection.
