According to Sink — who did her best to avoid spoilers — the new season is “darker and scarier than ever,” while her character, Max, is going through an emo phase and “is not doing too hot.”

“No! Like I didn’t know she knew I existed! And if she would have asked me to be a tree in something I would have said yes in a heartbeat,” she explained.

As for Swift’s skills as a director, Sink summed up her feelings in one word. “Amazing,” she said. “Obviously, I mean she can do anything, so she was incredible at it.”

The fourth season of Netflix’s “Stranger Things” debuts on Friday, May 27.
