Tonight marked the end of an era for The CW's Riverdale, with the airing of the hit series' long-awaited episode "Chapter Seventy-Nine: Graduation". The installment -- which was initially supposed to serve as the Season 4 finale, before the COVID-19 pandemic delayed production on the series for several months in 2020 -- undoubtedly has a lot of emotion behind it. Not only does the episode see the high school cast members graduate from Riverdale High, but it wraps up a number of storylines that the series had in the works, before the series jumps seven years forward into the future in future episodes.
