So that's been super special and important.''Here's a look back at the off-screen and on-screen friendships that defined Stranger Things across its five seasons.Stranger Things: A lookback at the friendships that stole the spotlight View this post on Instagram Instagram PostAs a coming-of-age story, friendship has been an important aspect of Stranger Things. Before the evil monsters and their dark interdimensional realms took over Hawkins, it was just another town with young kids riding on bikes and playing Dungeons & Dragons in the basement.Joe Keery's comments suggest that the on-screen friendships eventually translated into real-life bonds that will stay long after the end credits have rolled. Across its five-season run, the Duffer Brothers' sci-fi saga gave us many memorable friendships, from the core four, Dustin & Steve, Robin & Will and Max and Eleven. Will, Lucas, Dustin and Mike, the four nerds playing D&D in Mike's basement, formed the heart of the show and their friendship remained the glue that held Stranger Things together across five seasons.While their everlasting bond defined many memorable moments, it also helped Will beat the Upside Down and defeat the Mind Flayer in the finale. In a pivotal moment from the final season, Will develops a special bond with Robin, who encourages him to be himself and channel his self-acceptance to unlock his true potential. It is only after Will lets go of his fears and accepts his sexuality and feelings towards Mike that he understands that his connection with Vecna's hive mind actually gives him power. Even in a pivotal moment, Stranger Things manages to highlight the bond of the group, which is equally strong off-screen.While Will and Robin emerged as unlikely friends in the final season, Steve and Dustin's heartwarming connection defined Stranger Things. As Steve became the 'babysitter' of the group, silently initiating one of the best character developments on the small screen, he formed a special bond with Dustin. Even while Dustin and Steve were poles apart and opposites in every sense, their genuine friendship stole hearts and is now more popular than romantic pairings in the series.What do Joe Keery's comments suggest about the show's cast?
