Sentinel Lyons

Sentinel Sarah Lyons is a Brotherhood of Steel member and the commander of the Lyons' Pride in 2277.

Background
Sarah Lyons was born in 2251 in the Brotherhood of Steel's Lost Hills bunker in California.

Some time after the Chosen One stopped the Enclave on the West Coast, the Brotherhood of Steel ruling council decided to send a contingent of soldiers to the East Coast with a mandate to recover all advanced technology from the Washington D.C. area and to investigate the reports of super mutant activity in the area.

And so a small but hardened contingent of Brotherhood of Steel soldiers, led by her father, an idealistic Paladin named Owyn Lyons (accompanied by his friend and technological adviser Scribe Reginald Rothchild) set out from the Lost Hills Bunker in California. This started the long trek east to what was once Washington D.C.

A permanent base known as the Citadel was built into and beneath the ruins of the Pentagon. Owyn Lyons (now Elder of the Capital Wasteland division of the Brotherhood) and his soldiers also found the super mutants in the urban ruins of downtown D.C. and helped to stop the mutant tide from overtaking the entire region.

In 2277, Elder Lyons' daughter Sarah is now a grown woman, but she is still one of the Brotherhood’s finest warriors, if not the fiercest. In fact, she’s the only member to have achieved the illustrious rank of Sentinel, and now commands her own elite squad, Lyons' Pride.

Sarah is unsurprisingly loyal to her father, but her superior attitude to wastelanders is more typical of those in the Brotherhood with lingering sympathies for the Outcasts. She has little patience with 'civilians' stumbling into the line of fire. However this may be the pride of a professional rather than someone who doubts the value of the Brotherhood's objectives. Her attitude to Initiate Reddin suggests she is not convinced that wastelanders should be recruited into Brotherhood ranks.

Quests

 * Following in His Footsteps: The Lone Wanderer encounters Sarah while traveling to the GNR Building Plaza. The PC will find her squad not far from the Tenleytown/Friendship Station exit to Chevy Chase North. When the PC approaches her, Sarah will not trust the wanderer but will allow him/her to follow behind them to the GNR studios. Upon reaching the GNR Building Plaza, the PC and Lyons' squad will be attacked by super mutants, and a super mutant behemoth Lyons will then enter the GNR building with the remainder of her squad. While there she can be talked to, and will thank the PC for his or her help if appropriate.
 * Take It Back!: Sarah, after inducting the Wanderer into the Pride, briefs you all on the mission to come. She personally accompanies the Wanderer into the Jefferson Memorial Rotunda for the final confrontation with the Enclave's second in command Colonel Autumn and his handful of personal guards. Based on the Wanderer's choice, Sarah Lyons will:
 * Watch the Wanderer's selfless act of sacrifice in choosing to enter the chamber and mourn his/her inevitable demise (unless Broken Steel is installed).
 * Enter the chamber herself, sacrificing herself in place of the Wanderer.
 * Wait until the Purifier explodes.
 * Who Dares Wins (Broken Steel): After the player escapes from the mobile base, Sarah Lyons will appear again (unless she was killed) and pick you up in a Vertibird, taking you back to the Citadel.

Effects of player actions

 * She will comment if the player is wearing power armor when fighting the Behemoth in the GNR plaza, saying he/she can wear it for helping them defeat it.
 * (Broken Steel) If you betray the Brotherhood and launch an orbital strike on the Citadel, she and the other Brotherhood members who picked you up will attack you in a fury, calling you a traitor. It is then possible to kill her, as she will no longer be an essential non-player character.
 * (Broken Steel) If the player activates the purifier himself/herself, or uses Fawkes, Sergeant RL-3 or Charon to start it; it is revealed that an energy spike knocked both of you out. Two weeks later after you wake up, she's still in a coma, "unresponsive but stable".
 * (Broken Steel) If Lyons activates the purifier, she was killed by the radiation and doesn't appear.
 * (Broken Steel) After completing all the main quests, she will comment that she wishes she could get to know the Lone Wanderer better, hinting possible romantic feelings for them.

Notable quotes

 * "Keep firing! They bleed just like anything else!"

 * "How dare you assault a soldier of the Brotherhood of Steel!"

Bugs

 * At the end of the game Sarah Lyons can glitch into either saying that the control room still isn't clear or repeat the phrase "Steel be with you!"
 * After Waters of Life, before speaking to Rothchild to start the quest Finding the Garden of Eden, Lyons will appear on the road leading from Arlington Library to the Flooded Metro, walking along the road to a point past the Nuka-Cola Plant.
 * At the beginning of Take it Back!, as Liberty Prime crosses the first bridge, she may jump into the water and stay down there indefinitely.
 * At any point in the game, Lyons may talk about the Enclave fortifying the water purifier, and about the Enclave having Vertibirds. This happens only in non-player character to non-player character conversations though.
 * If you begin the Take it Back! mission, then fast travel to Falls Church, Sarah Lyons may appear as a follower in the area.
