Warning! Yellowjacket's Season 3 spoilers ahead!

Long time no see, citizen detectives. Though theYellowjackets hive have had some complaints about the pacing of the plane crash drama's newest season, things seemed to pick up a bit around episode four with the death of one of the remaining seven confirmed adult Yellowjacket survivors, Lottie Mathews. A surprising death considering season two's accidental murder of another main character, Natalie "Nat" Scatorccio at the hands of Misty Quigley.

What's strange is that even as the season creeps along, as of episode seven, we still don't know who the killer was—despite multiple characters (Misty, Shauna and Walter) doing their damndest to figure it out. But after some serious Reddit deep-diving, I'm absolutely convinced of an unlikely murderer to be found in Jeff Sadecki, Shauna's husband.

As far as we know, Lottie's adult arc was far from over. After running a cult, staging a makeshift "hunt" which nearly killed Shauna and actually ended up killing Natalie, being sent to a psychiatric ward and subsequently being released from the ward, briefly living with the Sadeckis, becoming unreasonably close with Shauna's daughter Callie and finally, giving Callie Jackie's heart necklace (one which marks a person for death)—many loose ends have yet to be tied. So why is she dead?

We're as close to figuring out the killer as we are to knowing why—which amounts to very little. Many viewers have been led to believe that Shauna or Other Tai could have killed Lottie—they sure have reason to—but, Redditor grendila_ makes a strong argument for the less obvious happy-go-lucky goofball father, Jeff, as the cold-blooded killer. And they make a very compelling case for this accusation.
