There are approximately a million serial killers on Riverdale (plus or minus a few), but thus far, only one of these serial killers is responsible for putting Betty Cooper in a hole. That's the Trash Bag Killer, aka TBK, and he is bad, bad news. Like, murdered multiple women, hacked off their limbs, and put their body parts in individual trash bags, bad news. When Betty tried to arrest him, he kidnapped and almost killed her — leading to awful PTSD and terrible nightmares. The worst of it all? Right now, we have absolutely no clue as to who the Trash Bag Killer is on Riverdale.

At the moment, Betty is a bit tied up with a different (so we think) murderer: The person kidnapping and killing women off the Lonely Highway. Betty is convinced that Polly, her older sister, is one of his victims, though, thus far, there's only blood — and no body — to prove that Polly is dead. Either way, Betty is going to find out who is killing women in Riverdale, even if that means pressing pause on her Trash Bag Killer investigation and letting her pseudo boyfriend Glen take over TBK.

Is it possible that the Lonely Highway Killer is the Trash Bag Killer? Totally, and I wouldn't put it past Riverdale to connect these two stories in one huge trauma-inducing season for Betty. However, right now, we don't know what, if any, connection these killers have. Until Riverdale gives us a few more clues, here's the suspect list for TBK thus far — including a few wild theories from our Clubhouse conversation with the Riverdale After Dark podcast.

The Kinda Obvious One: Glen

I'll say it again: Glen is just Diet Charles. Betty's serial killer brother was also an FBI agent, also a blonde dude in his 20s, and also suspicious from the jump.

We haven't seen a ton of Glen, but when we do, it's so he can tell Betty something new about whatever serial killer she's currently obsessed with. Yet because Glen is the one delivering the information to Betty — not unlike Charles, who always worked side-by-side with Betty on investigations despite secretly being a serial killer himself — Glen has total control over what Betty knows, and doesn't know.

Is it possible that Glen is hiding info about TBK that would implicate him? Totally. Is it also possible that he's weirdly obsessed with Betty, the FBI agent who already had a ton of solved crimes on her resume before she joined the team? Absolutely, yes! And most importantly: If Glen isn't shady, well, why is he here?

The Blast From The Past: Chic

Look, as far we know, Chic — aka the guy who pretended to be Charles, Betty's real brother — is still in prison. However, during The Dipp's joint Clubhouse with the Riverdale After Dark podcast, co-host Pete LePage reminded all of us that technically, Chic is just enough of a wild card to be considered a viable suspect. And honestly, I'm ready to have that conversation!

For one thing, Chic would be so obsessed with Betty (his faux sister) to try and get her attention by murdering people. He also knows how to get rid of a body, considering he basically made the Cooper family accomplices in the death of "The Shady Man" during season 2. While it seems like Charles is also in jail too, I wouldn't be surprised if Chic was able to bust out of prison with resources his FBI boyfriend acquired during his time working for the government, be it a shady contact or legal loophole. I'm just saying — it could be Chic!

The Unlikely (But Imagine If They Went There!) Option: Jughead

OK, but hear me out. This idea was brought up during The Dipp's Clubhouse event, in which Alex Zalben talked about an idea someone threw out on their Patreon's Slack channel.

"I don't want to take credit for it, but I love the idea that maybe it's Jughead and when he's blacking out, and he's becoming the Trash Bag Killer," Alex explained. "I don't think that's true, but I think it's a very funny, if dark theory."

Well... what if it is true? We know that Jughead lost "a lot of time" during his drinking days in New York, and it's heavily implied that he has some trauma he's still reeling from that he simply cannot remember. While we don't know what this is yet, could this "missing time" and "trauma" all add up to Jughead secretly being a serial killer?!?

Look, probably not. But we know that Jughead was pretty pissed at Betty, who, once again, cheated on him with his best friend during their senior year of high school. We know that he said something to her via voicemail that was so harsh, they never really spoke until they both showed up in Riverdale. Could Jughead's subconscious have turned him into a murderer, all as a way to exact revenge on new FBI agent Betty? It would be an insane twist.

I highly doubt the show would go there — and as someone secretly hoping that Betty and Jughead end up together down the line, I'm not exactly itching for the show to detonate Jughead's character like that, just for a jaw-dropping twist. However, I do think it's possible for Jughead to believe, at least momentarily, that he is capable of being the Trash Bag Killer — and hey, maybe he's involved in the crimes in some non-murder-y way that he simply can't remember.

The Let Down: It's No One We Know

Shockingly, not all serial killers can live in Riverdale — even on Riverdale. We know that TBK killed women all over the country, and it's quite possible that the serial killer solely exists so that Betty feels extra guilty and determined to track down Polly's potential killer: In her mind, she already let women die because she couldn't solve the TBK case.

Still, that doesn't mean we won't ever meet TBK, or that his presence won't become known in some way on Riverdale.

"I don't think it's anybody secretly," Alex shared with The Dipp. "I think it's just this external thing, not connected to the Lonely Highway, not connected to the Mothman, but is this pressure on Betty from the outside that eventually he is going to work his way back to Riverdale. It's going to come in at the most inopportune moment and really mess things up. But otherwise, [I think] this is an unrelated mystery that's propelling Betty and putting stress on her throughout the season."

This makes a lot of sense, actually. Maybe TBK will show up, whether physically or just in terms of the story, just as Betty is finally tying up all her other cases. Still, not as much fun as the Jughead of it all, right?
