Volare!: Pete is a source for the Courier to gain reputation among the Boomers. The Courier can listen to Pete to learn about the Boomers' history to gain Fame, or ask Pete if there is any help needed at Nellis. He'll then direct you to Loyal.
I Could Make You Care: With Veronica as your active companion, listen to the history of the Boomers from Pete, but don't interrupt him. Once Pete is finished with the history, and you have talked to him about the Boomers, wait for Veronica to make a comment, then initiate dialogue with her.
After you've listened to the whole story, you have the option to ask questions about the Boomer people's history. The following question and answer (check) options appear, giving you the option to gain 230 experience and Boomer fame. If you can't meet the requirement, it's still possible to gain Fame (but not experience) by choosing the positive dialog option.
Why did your ancestors leave the safety of a vault?
Yeah, any detonation with a yield of less than half-ton of TNT is boring. (Explosives 40) - 40xp
I'm surprised Nellis was empty when your people found it.
Whereas your people had brought Geiger counters with them from the vault. (Science 35) - 35xp
How do you survive, totally cut off from the world?
You must cultivate soy or legumes for protein, in addition to grains. (Survival 40) - 40xp
What are howitzers doing at an Air Force Base?
That howitzer battery is a monument to the grit and resolve of your people. (Speech 40) - 40xp
How has Nellis taught your people to fly?
Oh, to slip the surly bonds of Earth and dance amid the soaring birds... (Speech 55) - 55xp
How did you learn where to find an old bomber?
You could attach ballast to the plane and then haul it here for repairs... (Repair 40) - 40xp
If you walk off in the middle of his story, you will gain Boomer Infamy.
Listening to the whole story will get you Boomer Fame.
Pete's voice actor Sam Cohen, will say "automatic warheads" instead of "atomic warheads" if the player asks him why the base was empty. This could have been an overlooked mistake during the voice recording, as in the subtitles, the word is "atomic". He also cutely messes up when he says "You're a sav- an outsider". He says it in a manner like a nickname; he was supposed to stop before he finishes the word "savage" and nervously replace it with "outsider" like many of the other Boomers.
pcps3xbox360 Pete may stop telling his story after the first part, wait a few times to get him restart the story and hopefully go on. You can use console code disable, then enable him again. This will reset him. (Only for PC) Bumping into him to move him out of his spot will make him move back to the place where he starts the story and begin again (on Xbox and PC).
ps3 Pete may glitch after telling the first phrase in his story, and his head will vibrate. He will not tell the rest of the story, or be able to be interacted with. Pushing Pete from his place results in Pete walking back to his spot and vibrating. Loading an earlier save (the auto-save through the door) or walking out and in again can correct the bug.
xbox360 Pete may not retell the story when prompted to. Walking out and in again "may" fix this.
xbox360 Pete may just repeat the same part despite retrying the above solutions but with no success. While he is still talking, continue to push him towards the door and cease when he starts to move back. There seems to be some kind of distance traveled requirement before he will go through the proper talk. Just nudging Pete doesn't seem to be enough.
