Stranger Things

Billy arrived at Hawkins High School in his black Camaro with his stepsister Max. As Max skateboarded towards Hawkins Middle School, Billy got out of his car and was noticed by several students including Steve Harrington and Nancy Wheeler as well as three other girls who admired his figure.

On October 31st, Billy waited to pick up Max from school. When she arrived, he chastised her for being late and said next time it happened she would have to skateboard home. On the way home, Billy noted that Max seemed to enjoy their new town despite her denial of this. Billy then asked her whose fault it was that they had to move to Hawkins; Max muttered that it was his. Billy was enraged by this comment and began speeding and yelling. Billy then threatened to run over Mike Wheeler, Dustin Henderson, Lucas Sinclair, and Will Byers as they were cycling home. Max said it was her fault that they had to move, and Billy swerved to avoid collision with the boys.

Antagonizing Lucas Sinclair and Steve Harrington

Billy joined the school basketball team and played against Steve, demonstrating skill and strength over him. Billy's team won easily against Steve's team. Billy also attempted to wind Steve up by talking to him about his relationship with Nancy in the school shower.

Billy eventually did leave Max to skateboard home one day when she was late. He left with a date.

One day, when Billy saw Max leaving her school with Lucas Sinclair. When Max got into his car, Billy told her that there are people in the world who she should avoid and that Lucas is one of them. Max tried to stand up for herself, but Billy tightly gripped her arm and reinstated his command. As they drove home, Max quietly cried. Billy was further angered by Max when he saw her with Lucas a second time at the arcade.
