Jethro was an agent of The British Sanctuary. After having a desk job for a long time, he decided to go out into the field to get a promotion, not knowing that it was much more difficult than he expected. While at a blockade around the premises of Tanith Low, Billy-Ray Sanguine quickly pulls him into an alley and gets him to tell him everything he knows. He calls him Jethro because he knew a man from Texas that was called that name. Eventually, even though he begs for his life, Billy-Ray kills him like the did to the first Jethro.
