(W) Roberto Aguirre Sacasa (A/CA) Francesco Francavilla. "Betty: RIP*" Part 4. 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? For TEEN+ Readers.
