After 15 long years,Supernaturalfinally ended near the end of 2020. Throughout 15 seasons,Supernatural’s mythology became more complicated and convoluted, going through multiple showrunners and creative teams, which made it hard to remember every plot thread. Well, hard for the writers. Fans, on the other hand, have been pretty good about pointing out the show’s flaws, both while it was on the air and ever since it went off. As Sam (Jared Padalecki) and Dean (Jensen Ackles) worked to avert multiple apocalypses, they did their best to make sure nothing went unresolved, but even they didn’t seem to catch everything. So, in honor of the show’s 15 seasons — and all the talk about apotential Season 16— here are 15 unresolvedSupernaturalplotlines for you to hunt down yourself.
Supernatural
Two brothers follow their father’s footsteps as hunters, fighting evil supernatural beings of many kinds, including monsters, demons, and gods that roam the earth.
Dean’s First Love Is Forgotten After Season 1
The first season ofSupernaturalfeatured some of the best monstersand moments, but one of the most personal plot points involved the introduction of Dean’s first true love, Cassie Robinson (played by future Arrowverse starMegalyn Echikunwoke). Cassie only ever appeared in one episode (“Route 666”), and a poor one at that, but in that time she helped the boys take down a racist ghost truck, and made an impression. Once the episode ends, Dean and Cassie say their goodbyes, with Dean confident that they’ll meet again (and maybe even settle down) down the road. Needless to say,Cassie never re-enters the picture, despite the show seemingly having more plans for her in the future. Yeah, it’s odd that we never hear from her again, but hey, that’s the tragic love life of Dean Winchester.
‘Supernatural’ Never Addressed How Death Changed Sam Forever
After Sam is killed at the end of the first hour of the two-part Season 2 finale “All Hell Breaks Loose,” Dean makes a deal with a demon to bring his brother back. After Sam is resurrected (with some serious strings attached), they finally take out the Yellow-Eyed Demon (Fredric Lehne), but not before the creature warns them that everything might not be as it seems. Azazel taunts Dean in the final moments before his death, asking how certain he is that what came back was “100% pure Sam.” While demons certainly lie (and that might be the case here), the show doesn’t really explore this idea further,despite Sam being increasingly more violent upon his return. Sure, Sam ended up using his demonic powers in Season 4, but that didn’t seem to be the difference that Azazel was alluding to…
‘Supernatural’s Deadly Sins Are Still Out There
After the Devil’s Gate was opened, thousands of demons and ghosts were released from Hell heading into Season 3, including the Seven Deadly Sins. According to Bobby Singer (Jim Beaver), the last time these demons were “topside” was during the Dark Ages (“The Magnificent Seven”). A few of the Sins were killed by Ruby (Katie Cassidy), but some of them lived another day. SinceEnvy, Sloth, Lust, and Wrath all survived their battle with the Winchesters, it seemed like they’d eventually return to finish the job. But they were forever a “no show.” Given their apparent importance in the demonic hierarchy, it seems unlikely that the remaining four Sins wouldn’t come back for revenge, especially when Hell needed a new leader afterCrowley(Mark A. Sheppard). With how often later seasons like to bring back characters fromthe more successful early seasons, it’s a wonder we never saw the remaining four Sins again.
Where Is Jesse Turner, the Missing Antichrist?
When Lilith (Katherine Boecher) begins breaking the 66 Seals to free Lucifer (Mark Pellegrino) and start the Apocalypse, the angel Castiel (Misha Collins) reveals to Sam and Dean that the young Jesse Turner (Gattlin Griffith)will eventually become the Antichristin Season 4’s “I Believe The Children Are Our Future.” Cass says that “with a word,” Jesse would destroy the heavenly host and the universe would never be the same. Throughout the show, both Lucifer’s actual son, Jack (Alexander Calvert), and even Sam have been referred to as “the Antichrist” due to their dark abilities, but Jesse, a half-human/half-demon cambion with god-like reality-warping abilities, is the real deal. What could’ve been an interesting turn of events later on in the series was completely forgotten asJesse’s role was filled by Jack by Season 13.
Some Horsemen Left ‘Supernatural’ Quicker Than They Appeared
The Four Horsemen of the Apocalypse arrive in Season 5 to usher in Lucifer’s arrival, and boy do they make an entrance. The final Horseman, Death (Julian Richings), would become a staple of the series for the next few years, but his brothers, Famine (James Otis), Pestilence (Matt Frewer), and War (Titus Welliver),never made it past their introductions. With their “power rings” still intact, fans have begged the question of why the remaining Horsemen never bothered to track down the Winchesters. It would have been easy to bring back these apocalyptic trailblazers, either to retrieve their rings from the Winchesters or hunt down Team Free Will for foiling their plans. Heck,since Dean killed their brother Death in Season 10, you’d think they’d be gunning for revenge.
Is Ben Braeden Actually Dean Winchester’s Son?
After first appearing in Season 3’s “The Kids Are Alright,” Dean has since speculated that he is the biological father of the young Ben Braeden (Nicholas Elia), the son of his former girlfriend Lisa (Cindy Sampson). In fact, Dean lived with Ben and Lisa for a whole yearbetween Seasons 5 and 6, leaving hunting behind. While some hoped (for Dean’s sake) that his story could end here, it wasn’t in the cards. While Lisa says Dean isn’t the boy’s father, he not only looks like the older Winchester but acts like him too (they even have the same music taste). In Season 6’s “Let It Bleed,”a demon possessing Lisa “reveals” that Dean is Ben’s father, but this line is mostly chalked up to “demon lies” (which is fair). Afterward, Dean leaves his foster family for good and forbids Sam from ever mentioning them again. If Ben is Dean’s son (and we have more reason to believe he is than not) that’s pretty cold.
One of ‘Supernatural’s Greatest Strengths Also Made the Show Iconic
Carry on, my wayward sons.
Jacob Never Came Back To Hunt Dean Winchester
In the Season 7 episode “The Girl Next Door," we learn that, as a kid, Sam made friends with a harmless Kitsune who refused to kill to survive. This kindly monster, Amy Pond (Jewel Staite), would later have a child of her own, one she needed to kill humans for, so he could survive. Against Sam’s wishes, Dean kills Amy, only for her young son, Jacob (Lyova Beckwitt), to walk in to see the hunter standing over his mother’s body. This traumatic event ends with Dean telling Jacob to “be good,”to which Jacob replies that he’ll hunt Dean himself one day. Jacob would have been a great addition for a “monster-of-the-week” episode later on, or even as Dean’s final nemesis in the series finale “Carry On,” but the writers either forgot about Jacob or the monster moved on with his life. More than likely, it was the former.
‘Supernatural’ Season 8 Didn’t Close the Gates of Hell
The whole point of Season 8 was thatSam and Deanwould finally slam the Gates of Hell shut forever, an honorable goal with an even more honorable end. With every demon down under, the world would be a much safer place andSupernaturalcould’ve instead focused on being amonster-hunting horror showlike it started out. Sam completes the first two trials with relative ease, which involve killing a Hellhound (“Trial and Error”) and saving a soul from Hell (“Taxi Driver”). But the final trial, “curing” a demon, is interrupted by Dean once the elder Winchester realizes that, for the trials to be complete, Sam will have to die (“Sacrifice”). This act saves Sam’s life, but it puts the world more at risk.Dean justifies his actions by saying that they have enough knowledge to turn the tide, but it’s all talk. Sure, Sam later cures demon Dean (“Soul Survivor”), but that’s about it. They never rescue another innocent soul from Hell (not really) and the Hellhound-seeing glasses are only seen once more. The tide never changes, and demons still walk the Earth. Nice one, guys.
What About All Those ‘Supernatural’ Monsters in Chicago?
Supernatural’s first real attempt at a spin-offoccurred in the Season 9 episode “Bloodlines,” which introduced us to the Chicago-based ensemble, including human CPD officer Ennis Ross (Lucien Laviscount), shapeshifter David Lassiter (Nathaniel Buzolic), and werewolf Violet Duval (Melissa Roxburgh). The episode revealed a mafia-esque monster conspiracy that secretly runs the Windy City. But fans didn’t exactly love the episode’s change of pace, andSupernatural: Bloodlinesdidn’t take off, which is a shame since Sam and Dean neverreturn to Chicago again. With the ultimate fates of Ennis, David, Violet, and the cast unknown, “Bloodlines” left us with a lot more questions than answers. But more than that,the Winchesters learn that five monster families hold a grip over Chicago, and they never go back to do anything about it. Spin-off or not, that doesn’t add up.
Where Did the Stynes Run Off To?
Speaking of stories that deserve some greater resolution, the Frankensteins (also referred to as “The Stynes”) completely disappeared after Season 10. While an easy explanation is that Dean, influenced by theMark of Cain, slaughtered the entire American branch of Stynes after they killed Charlie Bradbury (Felicia Day), it was said earlier that season that the immortal monster family lives all over the world. With tendrils on every continent, it doesn’t seem likely that these gruesome, power-hungry fiends would ignore an entire branch of their family tree falling to the ground all at once. Yet,the Stynes never show their face in America again after “The Prisoner,”forcing us to wonder why these magic-dabbling semi-zombies never took the bait.Supernaturalcould’ve used some more body horror anyway.
