Mama Murphy

"Mama" Murphy is a character in Fallout 4, and possibly a Psyker.

Background
Mama Murphy is one of the people taking refuge from raiders in the Museum of Freedom in Concord. She is a seer, having the power of "Sight", claiming such power comes from Chems, Fallouts version of drugs. She is most likely a Psyker since her predictions do in fact become true.

Mama Murphy uses chems to induce a trance-like state in which she claims to see "things that were, things that will be, and even some things that are, right now." She uses her power out of a desire to protect people she cares for, providing warnings of danger and advice on which courses of action to take.

She sometimes mentions her past when the Sole Survivor comes near her or offers her drugs. She apparently engaged in a lot of unarmed combat in her youth and claiming to tear off a raider's head with her bare hands, earning the nickname "Murphy the Madwoman" and saying she used to be more muscular than the Survivor is when offered Buffout.

Other interactions

 * During When Freedom Calls if talked to she will be the one to reveal Dogmeat's name, and if passing a speech check, she will foresee a Deathclaw attack...which upon completion of the quest, may comment on how she killed a deathclaw with a single shot, without any fancy power armor or minigun back in her youth.
 * Upon completing When Freedom Calls quest, Mama Murphy commends the Sole Survivor's success and reports the player character's son is alive, somewhere in the Commonwealth.
 * After giving her Jet she will request that the player character make her a special chair called Mama Murphy's chair.
 * She will continue giving vague, but ultimately true predictions with more and more basic chems, such as Buffout, Mentats, Med-X and Psycho. These predictions unlock new dialogue options that allow the Sole Survivor to avoid combat during main quest line missions, namely Nick's rescue and the standoff with the synth courser.
 * After asking for Psycho and delivering the prediction that follows, she will die, making all of the Minutemen mourne her death.
 * Alternatively, the Sole Survivor may pass one of two hard Charisma checks to convince her to give up chems entirely, at which point she will lose the Sight, and not offer this service.

Appearances
Mama Murphy appears only in Fallout 4.

Bugs

 * If one does not craft Mama Murphy's chair properly, she will be stuck sitting in the chair in the ceiling of the house in Sanctuary that has the main workbench attached. She will be above the kitchen with (usually) only her feet showing. One must shoot her feet until she falls out of the chair, then go into "edit" mode and bring the chair out of the ceiling and on the floor. She will then spawn back in normally and sit in her chair as normal.
 * She might refuse to get in her chair just standing next to it. When the player tries to speak to her she will tell the player that she needs to sit down, no other interactions can be made with her.
 * There are two possible ways to fix this:
 * Scrapping and rebuilding the chair may fix this bug. Once scrapped, the chair will become available to rebuild after waiting or sleeping for an hour.
 * By opening the console, selecting Murphy and typing.
