Holly Wheeler

Holly is the youngest Wheeler, the little sister who has spent years on the edges of Hawkins' chaos while the older kids fought monsters. As the series moves toward its end, she's no longer just watching from the sidelines — she's old enough to notice that something strange is happening to her, and to her town, up close.

For years Holly was the show's youngest observer, a kid glimpsed at the dinner table while the real danger happened elsewhere. Nell Fisher's casting signals a deliberate shift: the little sister finally gets pulled into the story she's always been adjacent to, and there's real anticipation in watching a childhood spent near the Upside Down catch up with her.
