The CW's Riverdale is coming to an end in just a few weeks and while the series' main characters have been left in the 1950s for the entirety of the series' seventh and final season, it sounds like things will be jumping back to the present for the fan favorite show's big sendoff — in a very unexpected way. The CW has released the synopsis for "Chapter One Hundred Thirty-Seven: Goodbye, Riverdale", the twentieth episode of Riverdale's seventh season and the series finale. The episode is set to air on Wednesday, August 23rd. According to the synopsis, we catch up with an elderly Betty in the present day who wants to relive the last day of her senior year with her friends — with all of their memories restored.
