Deacon

Deacon is a synth sympathizer living in the Commonwealth in 2287. He is a potential companion in Fallout 4.

Background
Deacon is a spy for the secretive pro-synth organization, The Railroad. When the Sole Survivor first approaches the group they discover Deacon has been covertly keeping tabs on their activities in the Commonwealth. He will vouch for the Survivor's character to Desdemona, citing their accomplishments in the wasteland and their potential usefulness. Should the Sole Survivor join the Railroad, Deacon will become a companion.

At first glance Deacon is a laid back, lighthearted individual with a penchant for toying with people by lying. In reality he proves to be a cautious loner who is slow to trust. As they travel together, Deacon informs the Survivor that he is a synth and shares his recall code: a verbal command that will provide information on the Institute at the cost of wiping his entire personality. As his approval rises Deacon will reveal that he was one of the original founders of the Railroad some 70 years before, and Desdemona is merely the figurehead for his shadowy leadership. However, passing speech checks cause him to break down and confess these are all lies. He then warns the Sole Survivor to be wary of malicious people who will deceive them to achieve their own ends.

Once Deacon has reached maximum approval he will confide in the Survivor that he feels out of place in the Railroad. He says that as a youth he was a member of the University Point Deathclaws, a gang who harassed people accused of being synths. Their antagonism escalated to a lynching which was carried out on unreliable information. Shaken by the killing, Deacon left the gang to become a farmer. He fell deeply in love and married a woman named Barbara, but the Deathclaws returned and murdered his wife. It was not in retaliation for Deacon's departure, but because they had learned - to both Deacon's and her surprise - that Barbara was a synth. In the aftermath of the slaughter Deacon swore himself to the cause of synthetic freedom and equality. He then thanks the Sole Survivor for putting up with his games and expresses appreciation for them being a friend he can trust.

Notable quotes
Deacon is known above the other companions to be rather sarcastic in his reactions.
 * "The big three for predicting people: caps, beliefs, and ego. Get a handle on what's driving someone, and you know where you stand."
 * "And here I was wanting to spend the day reading Proust. And then you have to ruin it."
 * "I really want to know how the Big One started. What idiot fired first? Why? What the hell did they think they'd gain?"
 * "Back before I met you I'd go whole days without massacring a bunch of things. Honest."
 * "But I had a point here. A lesson, if you will. There're other organizations out there. And, in time, I'm sure they're going to spoon-feed you their own patented form of bullshit. Ignore the verbage and look at what they're doing. What they're asking you to do. What sort of world they'd have you build and how they're going to pay for it."
 * (When told to stay) "Absolutely. And my eagerness is totally unrelated to wanting a smoke break."
 * "I never really much cared for the Minutemen. The idea sounds great. But you give small men big power and sometimes you'll pay for it."
 * "One time, I got a face change and was a girl for a few months. You should've seen the looks back at HQ."
 * (When you decide to keep Buddy) "This robot is a national treasure!"
 * "Insert something Shakespearean involving death and your inevitable doom here."
 * "We sure do a whole lot of that. Winning, that is!"
 * "We live to see another day. And night. Etcetera."
 * (After reaching top of Trinity Tower) "Alright. You got me up here... let's go down. Now?"
