Jillian McKinley Jillian McKinley is one of the vital escaped Tibbets prisoners . Like many of her escapee comrades , she carries one of the New Plague mutations – a piece in a large and lethal puzzle that the player needs , and the same virus that inhabits player ’ s own body . Background . Jillian is a striking woman in her late thirties , despite her unkempt , " wasteland " look when the player finds her . Her looks are only exceeded by her intelligence and skill with mechanics and science ( it ’ s rumored that her family came from an actual vault , which explains her high mechanical and science knowledge , but she never talks about her family – possible PC dialogue quest ) . It is because of this intelligence , and her enviable skill with all things mechanical , that her life was spared the ghoul procreation process ; a process that is usually fatal to humans . The ghouls found her ability with tools and cognitive thinking both refreshing and useful , almost to the point of making her an " honorary " ghoul . So , the ghouls charged her with gun smithing under the direct supervision of Hank , the ghoul gun and ammunition smith . Jillian made no protest since the alternative was probably a grotesque and horrifying death . Jillian was abducted by a retrieval robot not long after the Rusty Hooks found Bloomfield . Like many of her fellow prisoners , she headed out in a direction she was somewhat familiar . Day and night she braved the wastelands , evading creatures of nightmarish size and grotesqueness . She thought she might actually make it to her home , Bloomfield Space Center . However , a few days before she reached her beloved home , Jillian was captured by a ghoul patrol and taken to The Reservation as a slave and potential procreation catalyst . Luckily for her , the ghouls discovered her high intelligence and skills in mechanics , and decided to make her a slave . Interactions with the player character . Quests . Acquire Jillian - The player will find Jillian sweating away in a radiation suit in the little trade area on the surface of The Reservation . It will be made clear that the player may not speak to any slaves . However , the player may inquire about purchasing Jillian from Hank , though it will take a very charismatic person with a high speech skill to even get Hank interested in selling Jillian ( Hank is far too fond of Jillian , and even shows a bit of affection towards her , mostly because of her skill , which he admires and respects ) . Other options of acquiring Jillian is proving to the ghouls that the player can be trusted by freeing Harold from his capture and returning him to The Reservation , by foiling a trade scam that a human trader is conducting on the ghouls , by talking the guards into taking the player to meet Willem Clark by saying that the player knows about a hi - tech launch platform that is fairly functional , or by blowing the shit out of the ghouls , though the last option would be very tough due to the sheer number of ghouls and their formidable equipment . As far as Sid is concerned with Jillian , she couldn ’ t return sooner . He will be ecstatic if the player brings Jillian back to Bloomfield so he can return to his life of background obscurity . Appearances . Jillian McKinley did not appear nor was mentioned in any of the published games , but was to appear in the canceled " Fallout 3 " project by codenamed " Van Buren " . It is not certain if she will appear in any future " Fallout " game .
