With conversations about everything that went down in Hawkins reaching fever pitch, the writers of Stranger Things have now revealed that several dramatic moments from the final episode weren’t in the original script.

In a series of tweets posted to the Stranger Things official writers’ account, the creative minds behind the blockbuster-sized finale shared three scenes that were completely improvised by the cast.

The first scene revolves around Joyce Byers (Winona Ryder) and Jim Hopper (David Harbour). At one point, Joyce says goodbye to Hopper, who’s getting ready to fight the prison’s Demogorgon. Visibly upset, she urges him to be careful, saying that she doesn’t want to hold a second funeral for him. Then, in a sweet moment that actually occurred spontaneously on the day of the shoot, they share a kiss.
