It’s time to start running up that hill again. But since it’s been more than three years since “ Stranger Things ” aired its fourth season finale, the trek might be a little rough for those who haven’t re-binged the Duffer brothers’ hit Netflix series before it debuts Volume I of the fifth and final season Nov. 26 at 5pm PT.

It’s been over three years since “Stranger Things” Season 4 hit Netflix, leaving plenty of fans in need of refresher ahead of Season 5.

During season 1, which premiered in 2016 and took place in November 1983, the core characters — Mike Wheeler (Finn Wolfhard), Eleven/Jane Hopper (Millie Bobby Brown), Dustin Henderson (Gaten Matarazzo), Lucas Sinclar (Caleb McLaughlin), and Will Byers (Noah Schnapp) — were 12 years old.

The Duffer brothers and 'Stranger Things' cast tease what to look forward to in Volume 2 of the fifth and final season.
