Riverdale's premiere will be dedicated to Luke Perry and his character, Fred Andrews, as the show finally addresses Perry's death, which happened in March with three episodes of season three left to film. Shannen Doherty guest stars in the episode, and you can expect some seriously heavy emotion, for the actors and the characters.
Don't, however, expect to get all the answers about that spring break flashforward, other than the fact that Jughead is MISSING in the trailer we debuted exclusively.
