User blog comment:Argorrath/Treyarch releases a BO2 teaser video called "Origins" for DLC 4/@comment-1639863-20130807222334/@comment-90.212.225.109-20130807223440

This is a great theory but if this is their idea it has left the story open as it wont go into detail about samantha being trapped in agathar

That said the robot could just be what you use to reach her and this is just setting the plot
