Doctor Duff

Doctor Duff is a resident of Diamond City in 2287. She along with Professor Scara both work and reside in the Science! Center.

Background
The open and easy-going Doctor Duff is the public face of the Science! Center, responsible for interacting with visitors and schoolchildren on field trips. She's a treasure trove of knowledge, particularly relating to biology, and doesn't shy away from sharing it with anyone willing to listen. She is also very absent-minded and impulsive; someone who would start a project and have to apologize if it got in someone's way. That someone is usually her lover, Professor Scara. The pair operate as the classic "odd couple." While Duff has a multitude of experiments running simultaneously, Scara focuses on one at a time, even when Duff tries to get her to help her. Duff has also has taken to cleaning up their home and laboratory, to the chagrin of Scara, who didn't want her laboratory space rearranged.

During the quest Liberty Reprimed, Duff will ask the Sole Survivor to rescue Professor Scara from the General Atomics Galleria. With Scara's absence, Duff is depressed and uninterested in her work, feeling hopeful for Scara's return. Duff: "Oh... it's you. If you brought any Bloatfly Glands, why don't you bring them back later. I'm not in the mood to deal with it right now." The Sole Survivor: "If something's wrong, maybe I can help." Duff: "It's my colleague, Professor Scara. Her normal field expeditions never last more than a few days, but it's been over a week now. I'm afraid something terrible has happened to her." Cait: "Gone for a week? Got bad news for you, love... either she eloped or she's dead." Codsworth: "Oh dear. I hope she's all right." Curie: "We should help find her." Danse: "That doesn't bode well. She could be in trouble." Hancock: "Yeah, that sounds about right." Robert MacCready: "Yyyeah... you might want to start looking for someone else to bunk with." Piper Wright: "Gone for a week. Blue, she could be in real trouble." Preston Garvey: "That doesn't sound good. We'd better go find her." Strong: "Then human was weak." Nick Valentine: "Chance of survival after a week out there ain't that great for someone not used to roughing it." X6-88: "That seems likely." (Duff's, Cait's, Codsworth's, Curie's, Danse's, John Hancock's, Robert MacCready's, Piper Wright's, Preston Garvey's, Strong's, Nick Valentine's and X6-88's dialogue) Scara, joining the Brotherhood of Steel, leaves her without her partner.
