Myrna

Myrna is a Diamond City vendor. She and her robot assistant Percy run the Diamond City Surplus trade shack. She is available to trade with during the day and Percy takes over at night. She sells weapons, apparel, aid, miscellaneous, junk and ammo. She sells shipments of steel, adhesive, springs, fertilizer, ceramic, and plastic.

Background
Myrna is a trader situated in Diamond City. She suffers from a lot of Synth paranoia and initially asks the player if they are a synth or human. After the player confirms they are human, trading can be accessed. If the player tells Myrna they are a synth, she will not sell to them unless they convince her they are human. Myrna's dialogue often implies that the player may be a synth.

While at her stall during the day, she will periodically accuse residents who come to shop or chat with her of being synths, leading them to leave in frustration.

Percy was hired to work with her because she does not feel safe to trade at night due to the synth propaganda. They effectively have two shops with separate caps piles, making it easy to wait for either to come back out.

Appearances
Myrna appears only in Fallout 4.
