Archie (K.J. Apa) and Ms. Grundy’s (Sarah Habel) relationship was exposed on the latest episode of Riverdale.
Betty (Lili Reinhart) confronted Archie when she saw him and his father Fred (Luke Perry) having dinner with Ms. Grundy. As Archie tried to explain himself, Veronica (Camila Mendes) overheard and neither of them approved of what Archie was doing.
Using her journalist instincts, Betty roped Veronica into investigating Ms. Grundy and the pair broke into her car. In there they found a gun and a driver’s licence with a picture of Ms. Grundy but bearing a different name.
They shared their findings with Archie and he confronted her. Ms. Grundy explained that she was in an abusive relationship and had changed her identity so she couldn’t be tracked down.
Betty’s mother Alice (Madchen Amick) found Ms. Grundy’s gun hidden in Betty’s drawers and after reading her diary found out about the affair. Alice dragged Fred to the school where they caught Archie and Ms. Grundy together. Betty threatened to deny her mother’s story if she spread the word about Ms. Grundy and the group agreed it would be best if the teacher left town.
Meanwhile Cheryl (Madelaine Petsch) stirred up trouble for Hermione (Marisol Nichols) when she took a photo of her talking to a member of the Southside Serpents gang. She informed Veronica about what she’d seen and when confronted Hermione tried to brush it off.
Veronica caught her mother meeting with the man again and let Hermione know what she’d seen. It transpired that Hermione was trying to clear up the mess her estranged husband had made.
Elsewhere Kevin (Casey Cott) found himself attracted to Southside Serpents’ member Joaquin (Rob Raco) and the two made out, Sheriff Keller (Martin Cummins) found that his office had been ransacked, and Jughead (Cole Sprouse) was revealed to be the son of the Serpent’s leader.
The next episode of the season is Chapter Five: Heart of Darkness. With Jason’s funeral around the corner, the Blossom family moves forward with last minute preparations – and a secret agenda.
