Jessup

 is the leader of the Great Khans living in Boulder City in 2281.

Background
He is holding NCR troops hostage. He also accompanied Benny who shot the Courier in the opening cutscene. He also argued, albeit briefly, with Benny over the burial of Chance, whom he had watched out for since the onset of Benny's mission. Jessup was able to easily intimidate Benny into allowing the burial, as the other Khans backed his threat.

During many portions of the graphic novel he exhibits fierce loyalty to the Khans and more personally to Chance, watching over the troubled man as if he were a brother or son. It is no surprise that later in Boulder City he holds sway over them as a leader figure.

Appearances
appears in Fallout: New Vegas and All Roads.

Bugs
If you help Jessup get out of Boulder City without killing anyone (through the speech check) he will say he has a long walk ahead of him, if you meet him at the Great Kahn settlement in Red Rock Canyon, he will still say he has a long walk ahead of him.
