"REGGIE MANTLE IS THE BRAVEST BOY I KNOW." — From Roberto Aguirre-Sacasa and the writers of the new CW series Riverdale, this ALL-NEW, ongoing comic series features stories set in between episodes of the new CW TV series Riverdale. Reggie's harboring a deep, heartbreaking secret that only Archie knows about – but is there more to Reggie's story than he's saying? And will the whole world know the truth about Reggie Mantle just as prom night arrives?

- Initially scheduled to release on March 7, 2018, it was delayed to March 14, 2018 along with other titles from Archie Comics, such as Archie Jumbo Digest #287, Cosmo #3, and Vampironica #1. 
- The novel Riverdale: The Day Before seemingly retcons the events of this issue as having taken place before the series began back when Reggie was still in sixth grade. The presence of Veronica already in Riverdale during the events of the comic points to the fact that this story was originally meant to take place during the show's present day timeline.
