Jack (Great Khans)

"Dude, what a total haul. No way that's copasheshy."

Jack is an easy going drug dealer for the Great Khans living in the Mojave Wasteland in 2281.

Background
Diane and Jack are advisers to Papa Khan. The pair run a drug trafficking ring and supply the Great Khans with drugs as well. It is implied that they have an emotional attachment to each other, or at least Jack does since he becomes upset when told that the Legion would put Diane into slavery and make her a prostitute.

Quests

 * Aba Daba Honeymoon: The player, with sufficient Science and Survival skills, can teach Jack how to make other chems such as Party Time Mentats, Slasher, Rocket (consumable), Hydra, and Super stimpak (Fallout: New Vegas) in exchange for Great Khan fame and a choice of 50 caps per recipe, chems, or a karma boost if the player chooses the 'just helping out' option.

Other interactions
After Aba Daba Honeymoon is completed, Jack will start to stock his supplies with the newly-taught chems, saving the player from having to gather/make them.

Appearances
Jack appears in Fallout: New Vegas.

Bugs

 * When you give Jack a new recipe for a Chem, the screen will black out, and roughly a few hours pass. After that, the screen will zoom in (maybe to begin dialogue with him), and then zoom back out and have another time lapse.
 * Jack's speech challenge for the "Oh My Papa" quest (speech check 60) can be repeated an infinite number of times, even after the quest has been completed. This challenge earns 60 experience points each time it is performed, allowing the player to gain infinite experience points. However if you rescue the runner Diane said went missing, you will not be able to use this exploit. (Still works after patch 1.02 on )
 * After teaching Jack all of the chems in the quest "Aba Daba Honeymoon" and finishing Diane's portion of the quest, you may not be able to finish the mission or learn the unarmed attack "The Khan trick". (Unconfirmed)
