Jughead Jones is in deep with the Jason Blossom murder case. Since the second episode of "Riverdale," he has worked with Betty Cooper to uncover the killer's identity, but there's more to his involvement than meets the eye. Speaking to CBR and other reporters, Jughead himself Cole Sprouse discussed why his character was so interested in the case -- and why he originally believed Jughead was the killer.

"The way that I had read Jughead was that he really considers himself to be a special snowflake. I think anyone who takes a stance as the observer and the watcher and one who can write 'objectively' about other people fashions themselves -- not with a superiority complex, so to speak -- but at least with this idea that they are qualified to do so, which complicates where Jughead stands," Sprouse explained. "I also think he's one of those guys who would much quicker criticize someone else's moral complex than point the fingers at himself. I think he judges and he builds his own personality based on how other people act within the town. Including himself within the narrative of Jason Blossom's murder is really an exercise of self for Jughead, but he has a personal stake in it as well. He's a member of this small town that's deeply interwoven with this tragedy and so -- across the latter half of the season and really from episode 7 onward -- you find out that Jughead has a tremendous stake in Jason Blossom's murder case and it really ends up getting revealed over time."

However, that doesn't mean Jughead killed Jason Blossom himself, though Sprouse once thought that may be the case. "From the very beginning, I have thought Jughead was the killer. That was informed by a bunch of different things, and the narrative still rings true but Roberto wrote 'Afterlife With Archie,' in which Jughead was the antagonist, and -- in this dark version of the universe as well -- Jughead had a shifty, outsider perspective," he shared. "He's also the only one that speaks to the audience and breaks fourth wall, which gives him the ability to inform the audience that he's the killer without having to inform any of the cast living in Riverdale, which ends up being a kind of dubious position to take. I'm not going to spoil too much, but that's kind of where I had planted myself from the very beginning, was the notion that Jughead was some sort of creepy kid."

Nevertheless, the identity of Jason's killer didn't come as much of a surprise. "I think I was surprised when we find out the culmination of the narrative but I think I'd also spent the last six months (or however long I've been here) exercising theories and pointing fingers and blaming just about every person on the cast. So, when one actually takes hold, which is inevitable, I'm excited that the theory takes hold but I can't say I didn't see it coming," he added.
