On November 7, 1983, the Wheeler family had a family dinner where Mike and Nancy got into a loud, verbal fight, startling and scaring Holly. Karen became angry with Ted and left the table, taking Holly.
Two days later, Holly and her mother visited Joyce Byers. Holly followed Joyce's flickering Christmas lights to Will's room and saw the monster begin to push through the wallpaper. Joyce asked Holly if she saw anything, and Holly responded with a yes. Joyce then insisted for the two of them to leave.
Three days later, Ted, Karen and Holly were placed under house arrest while agents from the Department of Energy searched their home.
One month later, after Will's rescue from the Upside Down, Holly is seen with her family celebrating Christmas together.
On October 29, 1984, Holly Wheeler was with her parents in the kitchen watching Nancy chase Mike for taking money from her piggy bank so he could play at the Palace Arcade with his friends. On the next day, Holly is eating at the dinner table as her parents tell Mike to fill two boxes of his toys for a yard sale.
Four days later, while eating breakfast with her family, Holly is asked by Mike if she likes the grapes she's eating. She then listens to Nancy asking if she could spend the night at a friend's house which her mother says yes (unaware that Nancy plans to expose Hawkins Lab with the help of Jonathan Byers to Murray Bauman as payback for causing the death of her best friend, Barbara Holland.).
In 1985, a couple of days before July 4, Karen decided to meet Billy Hargrove for swim lessons at a local motel. However, when she saw Holly sleeping on her father's lap as he slept on his couch, Karen changed her mind as seeing her youngest daughter and her husband caused Karen to realize how she's missing out on her family by being seduced by Billy.
On the Fourth of July, at the Fun Fair, Holly was with her parents, having fun as they were about to go on the Ferris wheel. When they reached the top of the wheel and stopped, Holly and her parents got a perfect view of the fireworks. Holly noticed some trees in the distance moving and tried to tell her mother, but Karen urged her to keep watching the fireworks.
Later, as Holly got on the Gravitron with her parents, Holly watched as her mother was approached by Joyce Byers and Jim Hopper, asking where Mike, Nancy, and their friends are. Holly enjoyed the Gravitron as it started and watched as Joyce and Hopper ran off, listening to her parents remark how Joyce and Hopper make an odd couple, which unknown to the three of them, the two were pursued by Russians led by hitman Grigori.
PersonalityHolly is an adorable and innocent little girl. Though she's very young, Holly is shown to have some degree of intelligence as she noticed Joyce's Christmas lights flickering and the Demogorgon, the Mind Flayer moving through the trees during the 4th of July celebrations, and was able to say more, according to Lucas Sinclair. However, Holly can also get scared especially when her brother and older sister were arguing over Will and Steve Harrington, Holly started crying as their outbursts frightened her.
