Felicia

Felicia is a "cut" non-player character still present in the game's files of Fallout: New Vegas in the form of a merchants container and a reference in a script.

Background
Based on the resources which remain relating to them, she was in some way tied to the Sunset Sarsaparilla Headquarters, and possibly the quest The Legend of the Star. In particular, the script which controls the more general dialogue surrounding the Sunset Sarsaparilla Headquarters includes a section, now empty, which is described as containing variables for Felicia.

Interactions with the player character
The disconnected cell in which Malcolm Holmes' merchant container is placed also contains a merchant container with the Editor ID (RefID, FormID ), identified as "Felicia's Merchant Container". As this container is placed in a cell meant to house non-player characters met in random encounters, it is possible she was intended to be encountered much like Malcolm Holmes.

Merchant inventory
The contents of Felicia's merchant container are as follows:
 * 1 conductor
 * 1 leaf blower
 * 1 sensor module
 * 1 scrap metal
 * 1 pre-War toaster
 * 3 plasma mines
 * 4 pulse mines
 * microfusion cells (varying types and amounts)
 * energy cells (varying types and amounts)
 * 300-2400 bottle caps

This container is set to respawn, possibly indicating that Felicia was intended to be a more permanently located non-player character or able to be encountered multiple times.

Appearances
Felicia was added during the development stages of Fallout: New Vegas, but was cut from the final retail release of the game.
