Lily (Fallout: New Vegas)

Lillian Marie Bowen is a nightkin living in Jacobstown in 2281.

Background
Born in 2078, just a year after the Great War, Lily lived a simple life in Vault 17, until the Master's Army raided the vault. The 75 year old grandmother was dragged outside, where she saw the sun for the first time. She was taken to the Mariposa Military Base and dipped into the vats of Forced Evolutionary Virus. She would emerge as a nightkin and was then on used as a spy or an assassin, with Tabitha as her squad leader. It was during this time that Lilly made her sword from a blade of the Vertibird that crashed near Klamath. It was also during this time that she developed multiple personality disorder, this personality "Leo" would "show" her how to craft the blade.

With the fall of Unity, the destruction of the Cathedral and the death of the Master, whom she didn't like, she decided it was time to go home. She and her squad led by Tabitha eventually met with Marcus and formed a community at Black Mountain. When Marcus and Tabitha parted on less than amicable terms, Lily traveled with Marcus to Mount Charleston to begin anew.

Eventually, she made it to Jacobstown, where she now lives as a herdsman, tending to the bighorners. Recently, however, the local nightstalkers had developed a stealth mutation, managing to hunt the domesticated bighorners as prey. Should the Courier choose to intervene, Lily would like to become involved.

While living at Jacobstown, she got help from Doctor Henry for her schizophrenia, brought on by excessive Stealth Boy usage and manifesting itself as a split-personality named "Leo," with anti-psychotics drugs. The side effects of the drugs however is memory loss. Unwilling to forget her past, in particular her grandchildren Jimmy and Becky,  she chooses to take her medicine at half-doses. An act personified by listening to a holotape of the last time she visited her grandchildren.

The "Leo" personality manifests itself as a malicious deviant and sociopathic voice she can communicate with, "He" instructing her in battle and telling her to do "terrible things>" She sometimes listening to it when she gets mad. "He" in turn doesn't like being called a voice in her head. In stark contrast is Lily's natural personality, friendly, helpful, and pleasant. Due to her nightkin training, she can help the Courier with their stealth. While she claims to not like guns that doesn't mean she is incapable of doing so, just that she, and "Leo," prefer to use bladed melee weapons.

When Doctor Henry began his work on developing a cure for the nightkin schizophrenia she asked his permission to help. She even still wishing to help after he informed her of the risk of permanent brain damage. Should the Courier help her and Doctor Henry with the completion of the cure, Jacobstown will prosper. Furthermore should the Courier help convince her that she was correct to take her medicine at half doses she will eventually leave Jacobstown to seek the remnants of her past. However if she is convinced that she should take the entire dose every time she will forget the importance of her past and throw away her holotape. Or, if she is convinced to stop taking her medicine then she will be consumed by the Leo personality becoming nothing more than a ravening beast.

Inventory
Additionally, Lily has a third companion weapon, a power fist variant called Lily's gauntlet. This weapon is not initially in Lily's inventory, but may be given to her as part of a script which ensures all companions retain their special weapons.

Lily is limited in the weapons she can use, and can only theoretically equip weapons from the following list.

Note: Lily's default assault carbine does so much base DPS that she will never equip certain weapons in practice; these weapons are crossed out.

Due to the above limitations, there are only two holdout weapons which Lily is capable of using: frag grenades and plasma grenades. This makes Lily a less-than-ideal companion when performing quests which take place in "weapon-free" areas like the Strip's casinos.

Appearances
Lily Bowen appears only in Fallout: New Vegas.

Behind the scenes
Lily Bowen was written by Travis Stout.

Bugs

 * Lily's vertibird sword and assault carbine may occasionally clip into one another, causing whichever one she's using to have the other hanging from it. The sword may also be replaced entirely by the gun. She will not shoot with the gun, however; she will continue to use it as a melee weapon. Opening her companion wheel and forcing her to switch between melee and ranged attacks a couple times will fix this glitch.
 * Sometimes when going into stealth mode, Lily will say her normal line, "Oh, don't you worry about me dearie, your grandma knows how to stay quiet," but will repeat it every 20–30 seconds.
 * Even before recruiting, if you talk to Lily, she will comment on things like Lucky 38 or Benny being killed.
 * After killing the mercenaries that are at Jacobstown she may randomly attack the player then fall unconscious.
 * On rare occasions, Lily may die before she is recruited as a companion in a non-hardcore game.
 * Sometimes, when Lily is equipped with Oh, Baby! she will randomly lose the weapon. It will no longer be in her hands or in her inventory, where it would normally go if it were to break from use.
 * If Lily is asked to use ranged weapons, she may not take out her assault carbine, and instead stay with her vertibird sword, or bumper sword if it is in her inventory. Even if switched back to melee, she will still stand near the courier, trying to use a melee weapon as a ranged weapon. This can be fixed by switching her back to ranged, then back to melee again; however, there is not a fix to make her use her Assault Carbine, because the next time you switch her to ranged, the bug occurs again.
 * If the player dismisses Lily to the Lucky 38 penthouse, she will not always make it there, but instead found in the Casino section, able to recruit again and dismiss to the penthouse without issues.
 * When the player character is sneaking, Lily may not enter sneak mode along with the player, and instead will walk along as if the player was not sneaking.
 * If the player dismisses Lily while they are sneaking, Lily will remain in stealth mode until recruited again.
 * Lily may disappear on the way to Jacobstown during Guess Who I Saw Today, if she is sent to the Lucky 38 and then asked to take Doctor Henry's test for the Stealth Boy Mark II without re-hiring her. However, it will still be possible to complete the mission regardless of whether or not she's actually there, though she may not be hirable again unless somehow found.
 * To fix this, either access the dismissal terminal and dismiss all companions, or reload a previous save. The former should bring Lily back to the Lucky 38's presidential suite.
