Alexandra Alexandra is a bounty hunter who is working for Caesar ' s Legion in 2253 . Background . She was an ' attractive ' woman in her late 20s , with dirty blonde hair tied back in a pony - tail . Usually wears worn denim jeans , a t - shirt , cowboy hat , and a duster . She ' d look more attractive if it weren ' t for the perpetually icy look in her gray eyes . She ' s not an ice queen , though ; it ' s just the tough mask she wears to keep trouble away – especially the male kind . Alexandra was raised a Mormon in New Canaan , the youngest daughter of a skilled physician . Unlike her seven brothers and sisters , Alexandra was always a bad seed , so it was no surprise to anyone when she left home at age 16 after a particularly vicious argument with her parents . She hooked up with a caravan bound for Hoover Dam . The only things she took with her were the clothes on her back and the medical knowledge she picked up from reading her father ' s books . Though Alexandra started out as a doctor for caravans , she ' s branched out into other professions as well , like caravan guard and bounty hunter . She feels that a well - rounded person is a prosperous person . Now 28 , she feels like she ' s doing fairly well for herself . When the player encounters her , Alexandra will have cornered the super mutant Blackjack in a cave near Mesa Verde . Caesar ' s Legion has put out a hefty bounty on live super mutants , and when Alexandra spotted Blackjack traveling alone , it was too good an opportunity to pass up . Alexandra became a cynic early on in life . She saw no reason for herself or her family to suffer just so total strangers could be taken care of , especially since such strangers might decide to take advantage of the Mormons ' charity . Her belief was justified she heard the news that New Canaan had been overrun and destroyed by desperate refugees . Her self - satisfaction was dimmed somewhat by the fact that none of her family had survived the looting and slaughter . Although she ' s a doctor , she ' s not a particularly compassionate one . She won ' t go out of her way to cure the sick , and she ' ll certainly not do it for free – medical supplies are expensive and often hard to come by . Furthermore , Alexandra can ' t stand it when healthy people beg for help . The way she sees it , as long as most parts of you are working , you can damn well fix your own problems . This may lead to situations where she makes an rude comment or two when an NPC is pleading for the PC ' s help . Alexandra has no agendas or goals , other than to survive . One final note : Never , ever call her " Doc " . Interactions with the player character . Effects of player ' s actions .
