The second season of Stranger Things introduced some new series regulars to the franchise. Sink's character, Max Mayfield, would quickly transfer to Hawkins Middle school and join the core group of students. Eleven (Millie bobby Brown) was envious of her presence, and Dustin (Gaten Matarazzo) and Lucas (Caleb McLaughlin) fought over who she liked better. By the third season of Stranger Things, she had become Eleven's best friend and Lucas' girlfriend. Her elder step-brother Billy Hargrove, played by Dacre Montgomery, joined her, and would go on to become the town's new bad boy before succumbing to the Mind Flayer in season 3.
