Aba Daba Honeymoon

Aba Daba Honeymoon is a side quest in Fallout: New Vegas.

Detailed walkthrough
Inside Red Rock Canyon, a path leads north to a group of resting campers; this is the Red Rock drug lab. This location includes Jack, a drug dealer who might be using his own chems, and his partner Diane. Speak with Diane about their line of work to begin the quest. She mentions that Anders hasn't reported back. Agree to find him.

Note: If Motor-Runner or Don Hostetler is dead, the quest will instantly fail.

Find Anders
Anders was last seen at Cottonwood Cove. The Legion has crucified him just outside the settlement. Three options are available:
 * 1) Talk to him to confirm he's Anders and then cut him down (this will not cause  infamy with Caesar's Legion.)
 * 2) Talk to him to confirm he's Anders and leave him (this will delay progress in the quest).
 * 3) Kill him, with or without talking to him first. This will not cause infamy with the Great Khans but yields no reward from Diane. Cutting him down and then killing him will not necessarily end the quest but will lead to infamy with the Great Khans.

After freeing or killing Anders, go back to Diane. Depending on which of the previous options was chosen, Diane will either provide 250 caps or nothing. Freeing Anders allows the choice to earn either 250 caps or a turbo recipe from Jack. In any event, Diane will mention that she is short-handed and needs a volunteer to deliver a "package" to the Crimson Caravan Company. Accepting yields a "mildly suspicious package."

Meet with Hostetler
Travel to the Crimson Caravan Company and go inside to the Crimson Caravan main office to find the buyer, Don Hostetler. Tell him about mildly suspicious package that Diane sent for him; he takes it and says to leave. Take the payment back to Diane to gain Great Khan fame and 150 caps.

OR Travel to Hostetler home at night, which is just south from New Vegas Medical Clinic (just follow the street). This may be the best option for those not in good standing with Crimson Caravan Company.

It's not necessary to complete this step to complete the quest. Speaking to Diane again will open up the dialogue about the Vault 3 Motor-Runner delivery, and completing that task will mark the Don Hostetler delivery completed even though no delivery was made and open up the reward dialogue. The mildly suspicious package will remain in inventory.

Meet Motor-Runner
Diane then goes on to mention her next task: a delivery of the highly suspicious package containing some Jet and Psycho to Motor-Runner in Vault 3. The Fiends outside will attack, but wearing the Great Khan simple armor that Diane provides (or any other Great Khan faction armor) will make the ones on the inside a bit more friendly. Inside the entrance to Vault 3 is a Fiend; wearing Great Khan armor or passing a Speech check of 64 will get her to reveal where her boss is. After navigating to Motor-Runner, start a conversation with him and tell him about his delivery.

The Courier can sell him drugs from their own supply (Jet, Psycho, Buffout) for 20 caps (or 22 caps with a Barter check of 65) by passing the Speech check at the entrance of Vault 3 with the Fiend at the door. 22 caps are the most that it is possible to receive from selling the drugs, which are valued at 20, with the exception of one instance involving Ricky.

After that, return to Diane to continue the quest. This nets Great Khan fame and 300 caps.

NOTE: If the Fiends are hostile: Failing the initial speech test and not wearing Khan armor upon entering the vault will turn all the Fiends hostile. Even though Motor-Runner and his dogs will then show he is hostile, the quest can still be completed by talking to him, but this requires that all other hostile Fiends in the area be either out of range or dead. It is possible to kill everyone in the vault besides Motor-Runner and his dogs without failing the quest.

NOTE: If Motor-Runner has been previously engaged in dialogue: Motor-Runner will not engage in dialogue with the player character after their initial conversation. However, it is still possible to complete the quest by making Motor-Runner hostile, either by attacking him or the nearby dogs/Fiends, and then running to the entrance room of the vault (where Vault 3 Fiend guard is first encountered). Upon holstering their weapon, Motor-Runner will then address the player character directly and inquire about the shipment from the Great Khans. (Killing all Fiends in the area first will make this much easier.) Using the console command "rdf" will reset his dialogue, allowing one to give him the drugs (be careful, this command resets ALL dialogues in the game).

Create chems
Meeting the following requirements will make it possible to teach Jack recipes for chems:
 * Science 50: Party Time Mentats
 * Science 50: Rocket
 * Science 50: Slasher

Passing a Speech check of 66 with Jack, or a Barter check of 50 with Diane, will convince them to expand their business and start making more medicinal chems. This opens up two more recipes to teach Jack:
 * Science 50: Super stimpak
 * Survival 75: Hydra

Passing each individual skill check results in 50 XP as well as Great Khan fame. The player character can then request caps or drugs as thanks, resulting in either 50 caps or one each of Jet and Psycho. Declining a reward will instead yield positive Karma. This is repeated each time they teach Jack a new recipe. Once Jack is taught a recipe, he will begin to stock that item for purchase.

Quest completion
After finishing all parts of the quest by fulfilling Diane's requests and passing Jack's conversation skill checks, the Courier can learn a special Unarmed move called the Khan Trick.
