Characters narrating a show is pretty popular these days, but it almost always leads to the question of whether or not it's just a fun storytelling device or actually significant. For instance, the most recent season of Jane the Virgin reveals that the series narrator not only knows things that are going to happen, but that the whole series is "based" on the main character's books. Similarly, it's not a stretch to imagine that Jughead is more than just a narrator — he's controlling the narrative we see, with ramifications we have yet to fully understand.
