Gladys Jones left Riverdale for a reason. Whether it was her husband FP or criminal matters, she picked up her life and took her daughter out of town. Those reasons haven't gone away. The past has a way of coming back from the dead.
Archie: Ronnie, when I first met you … you were it for me. Everything I could ever wanted. I saw our whole future. Veronica: Because we’re endgame, Archie. Archie: I hope you know how much I love you. Veronica: If you loved me, you would come home. Archie: God, Ronnie, you know in your heart that I’m right about this. It just hurts to admit it. Veronica: Don’t you make me say goodbye, Archie Andrews, because I don’t wanna hear it back. I can’t. I can’t. [She drops the phone, cries, and Kevin consoles her]
Veronica: What the hell is a "Sticky Maple"? Kevin: It's kinda what it sounds like. It's a Riverdale thing. Veronica: No, Kevin, it's a slut-shaming thing. And I'm neither a slut nor am I going to be shamed by someone named, excuse me, Chuck Clayton! Does he really think he can get away with this? Does he not know who I am?! I will cut the brakes on his supped-up phallic symbol.
