The road to hell is paved with good intentions on this week's Riverdale.

In Thursday's new episode, Betty (Lili Reinhart) decides to throw Jughead (Cole Sprouse) a surprise birthday party despite the fact the show's self-styled outcast would rather just share a booth with Archie (KJ Apa) and Veronica (Camila Mendes) at Pop's and pray everyone just ignores (or maybe even forgets) it's his big day.

Of course, because this is Riverdale — or more accurately, because this is high school — the small, intimate celebration quickly spirals out of control in a way that only Bogey Lowenstein or Cady Heron possibly could have predicted.
