Ambassador Dennis Crocker

 is the ambassador of the Mojave Wasteland for the New California Republic in 2281.

Background
Is the NCR ambassador to the Mojave area.

Interactions with the player character
Crocker writes a letter which an NCR soldier delivers to courier while on the New Vegas Strip. In the quest King's Gambit, after learning from Rotface that Pacer has a Jet addiction, return to the embassy. After telling Crocker this information, you'll have a special dialog option for Wild Wasteland, which causes Crocker to shout "DAMN IT, I'M AN AMBASSADOR NOT A DOCTOR".

Crocker gives the courier the quest, Things That Go Boom, which duplicates a quest given by Yes Man followed by the quest King's Gambit.

Bugs
If the Courier waits in the Embassy at night when Ambassador Crocker isn't around, waiting for him to appear in the morning/afternoon, he will not appear in the building. All you have to do is take your player and exit the Embassy and re-enter for the Ambassador and his secretary to appear in the Embassy. He will not always reappear though. This has been a bug in the game and you can no longer complete quests with the NCR because Crocker disappears permanently.

It is however possible to spawn the Ambassador if he disappears permanently using the following command:

''player.placeatme 1126401 ''

Appearances
appears in Fallout: New Vegas.
