Stranger Things, which debuted in 2016, explored Jonathan Byers’ (Charlie Heaton) search for his younger brother, Will Byers (Noah Schnapp), in the first season. As the hit Netflix series approached its final episodes, the brothers grew even closer when Jonathan comforted Will following his emotional moment with Mike (Finn Wolfhard).
Meanwhile, Riverdale threw some major obstacles at the Blossom twins when the 2016 pilot kicked off with Jason’s (Trevor Stines) disappearance. His twin sister, Cheryl (Madelaine Petsch), later discovered that he died before getting to run away from the small town.
Ahead of the CW show’s seventh and final season, Riverdale took the characters back to the 1950s — and introduced Nichola Barasch as Julian Blossom in this version of the story. In May 2023, Barasch praised Petsch for her help transitioning to set as her onscreen sibling.
