So @swampvendor informed me that they suspect that by season 2 the character Cheryl Blossom is writing her own plotlines in Riverdale. If you tie this to my statement that everyone is in a different show than Cheryl except for Jughead, and then note that Jughead is literally writing the events of at least episode 1 in the course of episode 1....
Riverdale is a Homestuck spin-off @swampvendor
