Ethyl

Ethyl is one of two Glowing Ones in The Chop Shop's containment area in The Underworld in 2277.

Interactions with the player character
Ethyl can't be interacted with as she is behind a plate of glass to an inaccessible room, but the PC can set her on fire with a flamer.

Appearances
Ethyl only appears in Fallout 3.

Behind the scenes
The name Ethyl is most likely a reference to an Alice Cooper song called Cold Ethyl which speaks of making love to a dead woman.
