Priah Ferguson as Erica Sinclair on Stranger Things 2 (2017)

“I can’t believe it,” she tells EW of the positive reaction. “I knew people would be excited, but I didn’t think it would be like this.”

The Atlanta native, whose biggest pre-Stranger credit was fittingly a small guest role on FX’s Atlanta, knew little of the Netflix hit before she was cast, and got some guidance from her family of “horror fans.” Among them was her own little sister, which means Ferguson is no stranger to sibling dynamics. But despite Erica and Lucas’ antagonistic relationship, Ferguson enjoyed her time on set with the 16-year-old McLaughlin, whom she adorably describes as an “amazing gentleman.”

As much as she loved Erica taunting her brother, it was picking on Lucas’ partner in crime that was Ferguson’s favorite moment of the season. “The walkie-talkie one was super-fun to me,” she says of the scene where Dustin’s (Gaten Matarazzo) desperate attempts to get in touch with Lucas for a “code red” are thwarted by Erica retorting with a “code shut your mouth.”
