Valerie is definitely in the show. Chuck isn't in the IMDB list, but I could have forgotten.
I've seen a million pictures where Sabrina is with Jughead and gives him magical burgers. I'm wondering if she's his new best friend or something. He's in her comics, too. I want her to be in it, but maybe next season.
Have you ever read Archie versus Predator? It's in Dark Horse comics and the idea of Archie being able to fight Predator is crazy, but it's also somewhat entertaining.
Cole think comics Jughead is creepy, not his version.
