Warning! Spoilers ahead

The Stranger Things stars went rogue while filming Volume II.

The show’s writers revealed on Twitter July 2 that three of the biggest moments in the season four finale weren’t actually in the script. It turns out the stars improvised at times, making their emotional scenes even more, well, emotional. 

Take, for example: Joseph Quinn came up with the idea to have a dying Eddie tell Dustin (Gaten Matarazzo), “I love you, man,” following his epic Demobats battle. 

The writers also said the same. Winona Ryder and David Harbour weren’t supposed to kiss before their fight with the Demodogs, but, the writers said, “Winona David added it on the day of filming.” 

Also Caleb McLaughlin‘s heartbreaking scene, in which Lucas cradles Max (Sadie SinkVecna almost killed her.Jamie Campbell Bower), was made up on the spot, too. Caleb was said to have improvised the “Erica help”, according to the authors.
