Background
Heather Holloway is the daughter of Tom and Janet Holloway. Before the summer of 1985, Heather became a lifeguard at the Hawkins Community Pool where she became co-workers with Billy Hargrove.

1985
In the summer of 1985, Heather began working as a lifeguard at the Hawkins Community Pool alongside Billy Hargrove. Her shift was always the one before Billy's. During one of her shifts, she finds Billy acting strange and goes to check on him. This proves to be a bad idea as Billy abducts her and brings her to the Mind Flayer, where she is converted into one of the Flayed. Her conversions is also seen by Eleven when she is spying on Billy, but she does not see Heather or the Mind Flayer. Eleven uses her powers to track down Heather after they figure out she's missing, and find her in a tub of ice, with Heather popping out, jump scaring Eleven and then falling through the floor in the Void. When Max and Eleven go to Heather's house, they find Billy with her parents Tom Holloway and Janet Holloway. Heather comes out of the kitchen offering Eleven and Max a cookie, which they refuse and then leave. Janet later doesn't feel so good, spills her wine, and goes to lie down, only to fall to the floor unconscious because of Billy and Heather poisoning the drinks. When Tom goes to check on her, Heather picks up an empty bottle and knocks him out with it. They then (as seen in a flashback) drag them to the garage, restrain them, and take them to the Mind Flayer, where they are then converted into the Flayed. She is next seen tending to Billy's injuries after his fight with Eleven, with Billy commenting on how Eleven, Max, Mike, Will, and Lucas know that he's Flayed. Heather responds that they don't know about the rest of us, with the shot panning out to show more members of the Flayed. She is mentioned in another episode when the group figures out that the Mind Flayer has control over more people (thus dubbing them as "Flayed"). She is last seen being melted by the Mind Flayer and merging with it to make it stronger, along with her Mom, Mrs. Driscoll, and the rest of the Flayed.

Personality
Heather is a sweet and sensitive neutral girl who hangs out with and works alongside Billy as a lifeguard at the Hawkins Community Pool. She seems to be both sympathetic towards and harbor some degree of feelings for Billy, prior to her abduction by him, as evidenced by both her flirtatious remarks towards him while walking past him during their shift switches, as well as her concern for his mental state while he was hallucinating due to his implantation by the Mind Flayer. After her abduction by Billy and conversion into one of the Flayed, Billy and Heather seemed to begin a romantic relationship, though this was likely a sham for the sake of the Hive Mind. Meanwhile, her personality became very one note and almost like an exaggerated version of her prior personality. She quickly became completely subservient to the will of the Mind Flayer, leading to the development of sociopathic tendencies as evidenced by the remorseless assault, abduction, and conversion of her parents by herself and Billy. By the end of her life, she became totally devoted to the cause of The Flayed, which ultimately led to her death.
