Betty: RIP: Part 4 - Written by Roberto Aguirre Sacasa. Art and Cover by Francesco Francavilla. The Horror began in Riverdale when Reggie Mantle struck and killed Jughead's beloved pooch Hot Dog. Since then, Reggie has been living with this secret knowledge-and terrible guilt. With no one to talk to about it, Reggie has started to crack under the strain. He is seeing visions of his dead friends - or are they literal ghosts? When an act of kindness prompts a confession from him, Reggie must decide for himself, once and for all-is there any good within him? Or is Reggie, as we've always suspected, beyond redemption? 32 pages, full color, Rated T+ Cover price $3.99
