Summary: The town of Riverdale has been hit by a nasty Civil War. People who are on the same side are beginning to turn against each other. Jughead Jones becomes the newest casualty of the fighting when he ends up in the hospital with a traumatic brain injury. While Jughead fights for his life, Betty is no longer fighting for peace. She is fighting anyone and anything that wants to rip them apart.
