in their hands, the Chosen One, along with the Arroyo tribals and the Vault 13 dwellers, founded the city of New Arroyo and reunited the two bloodlines that had been separated for three generations.
Canonically, the Chosen One was twenty years old by the time of Fallout 2, so he’d (or she’d) be sixty by the time the events of New Vegas. Given that Harold was able to walk across the country and survive, I would say the Chosen One’s still alive and kicking.
Personal life Arroyo resides in New Orleans with his wife Rebecca and their three children.
The Chosen One’s “Married” status then becomes “Separated”. Unlike Davin, she has a Strength of three, rather than four, which means she cannot use any SMGs without a strength penalty to her already-deficient skill, though she has a +50 to-hit bonus for short-range fire.
While the Chosen One was on their quest, on July 20, 2242, Arroyo was attacked by Enclave soldiers in Vertibirds, wearing power armor and armed with energy weapons, and the villagers were captured and brought to the oil rig. Some of them tried to resist the attackers and were killed, and Hakunin was seriously wounded.
Notes. The Lone Wanderer is named “Albert” in Fallout 3 previews.
“By 2297, the Lone Wanderer had disappeared from the Capital Wasteland, and their fate was unknown. Most citizens of the wasteland had a story about the Wanderer, and many of their actions had gone down as local legend. History had even forgotten their gender.
The Chosen One, is the player character in Fallout 2, and the grandchild of the Vault Dweller.
Edit 4: tl;dr Since NCR annexed as far as Klammath, and Arroyo is listed as a member-state of the NCR, yes, the land of Arroyo in under NCR control, though the Arroyans and people of Vault 13 founded New Arroyo elsewhere with the Chosen One of FO2.
Ask him if he can teach you some unarmed skill, and if he can, ask him to teach you some. Next, go to the west and repair the damaged well for a little bit of experience.
