Evelyn Evernever was a "Little Archie" character who was shown in the comic books in the 1950s.
The opening scene you see Archie in juvenile prison and it's a scene right out of The Shawshank Redemption (1994), from the older uniforms, the rotary phone, the needle point quote and even the warden looks like Shawshank's warden and both are named Warden Norton.
Archie's cell number and the episode number are the same, '302'.
The "Leopold and Loeb Dentention Center" is a nod to killers Nathan Leopold and Richard Loeb from Chicago.
The title of this episode references a movie which was shot in Canada, which goes the same for "Riverdale".
