Scribe Haylen

Scribe Haylen, registration HN-118FS, is a field scribe of the Brotherhood of Steel, living in the Cambridge Police Station in Fallout 4.

Background
Sometime after the Brotherhood-Enclave War, as the Brotherhood began recruiting throughout the Capital Wasteland, Haylen was accepted into the organization with Rhys sponsoring her induction and Danse sponsoring her training. Rhys took her under his wing during her training and during this time she began to believe that there was a possible romantic connection between them. However, when she asked him about it, he told her that the Brotherhood was the only thing that he cared about and the two never spoke of it again.

She became a scribe, serving in the Brotherhood's Order of the Quill. By 2287, she, Danse, Rhys, and four other soldiers had been assigned together to form Recon Squad Gladius, tasked with investigating the Commonwealth after the loss of Recon Squad Artemis three years prior.

The mission was difficult from the moment of their arrival; after establishing a stronghold at the Cambridge Police Station, Knights Worwick, Brach, Knight-Sergeant Dawes, and Keane all perished from attacks by raiders, super mutants, and feral ghouls respectively. Worwick's death was especially hard on Haylen; she spent two days treating his wounds before Danse ordered her to put him out of his misery via an overdose of painkillers. Despite their losses, Haylen still carried out her assigned tasks, monitoring energy readings from an unknown source and modifying the police station's radio tower to eventually call in reinforcements.

She is first encountered during the quest Fire Support and is responsible for the emergency broadcast the Sole Survivor hears. Later on in the Brotherhood questline, she can also be found at Waypoint Echo along with a couple of Brotherhood troops during the quest Liberty Reprimed, and onboard the Prydwen during the quest Blind Betrayal. Afterward, she will return to the police station and continue tasking the Sole Survivor with recovering pre-war technology.

She has certain doubts about the Brotherhood's ideology and practice. She joined out of idealism, but it was quickly confronted by brutal, pragmatic tactics that define Maxson's doctrine. While Haylen continues to work for the Brotherhood, she's constantly doubting herself over the morality of her chosen path.

Quests

 * Semper Invicta: She will welcome the Sole Survivor into the ranks of the Brotherhood.
 * Quartermastery: Travel to a random location and find a piece of technology for Haylen.
 * Blind Betrayal: Haylen is furious when Danse is accused of being a synth. She is angry at Quinlan for acting indifferently toward Danse's life and pleads with the Sole Survivor to speak to Danse and hopefully spare him. She can be questioned for information on Danse's whereabouts, leading the Sole Survivor to Listening Post Bravo.
 * If Danse is killed, Haylen will become very cold towards the Sole Survivor.
 * Regardless of her sympathies, if Danse is hired as a companion after Blind Betrayal, Haylen will be hostile to both Danse and the Sole Survivor.
 * Precipice of War: She, along with Rhys, will need to be killed during the Railroad's assault on Cambridge Police Station so a Vertibird can be captured.
 * Liberty Reprimed: Stationed at Waypoint Echo, Haylen sends the player deeper into the Glowing Sea to find weapons for Liberty Prime.

Appearances
Haylen appears only in Fallout 4.

Bugs

 * If Danse is spared during Blind Betrayal, Haylen may be removed from the game, making it impossible to complete Semper Invicta, without the use of console commands.
 * If the Institute is destroyed with the Minutemen and Semper Invicta is not completed, Haylen will pick up her dialogue as though Danse was spared and he is at the bunker, even though he will still be in the Cambridge Police Station.
 * Even when killing everyone at the Cambridge Police Station, Scribe Haylen will still comment on the Sole Survivor destroying the The Institute in her terminal.
