The 15 Worst Supernatural Plot Holes That Made No Sense

Goingon for 13 years now, Supernatural is one of the longest running shows out there. Against any and all odds, the fan-favorite program has stood the test of time; each year it acquires more and more fans. Though Supernatural’s central premise revolves around San and Dean Winchester, two brothers who fight monsters, it’s a less a show about creatures that go bump in the night and more an emotional odyssey featuring two semi-broken siblings. Appealing to nearly every demographic out there, Supernatural is a show that has something for everyone. Season 13 is currently underway and it wouldn’t be surprising if we got a 14th, 15th and 16th season.

With such a long history, the Winchester brothers have battled everyone and everything from the Devil himself to demonic Easter bunnies. Anything is possible in the world of Supernatural and the Winchesters have staved off the Apocalypse more than once. On account of having an extensive history however, the show’s writers have occasionally lost track of this and that. They think no one notices these tiny to Leviathan-sized plot holes, but noticed they are. Today at CBR we’re looking at 15 plot holes in Supernatural that still leave fans scratching their heads.


For the longest while it was Sam and Dean against the world. Their dad popped in for a hot minute, but then left just as quickly, leaving the brothers to fight the supernatural on their own. In season five, it was revealed they had another brother: Adam. At the season’s finale, Adam is thrown into The Cage, along with Lucifer and the archangel Michael and then…that’s it.

Season six revealed that it’s possible to escape The Cage, since Sam gets pulled out, albeit without his soul. In season ten, Supernatural’s writers teased they still remembered Adam during the musical when a director points out Adam's character in the drama; Dean and Sam's exchange awkward glances with one another. So while he’s dead and nearly forgotten, it’s about time all the Winchester brothers got together again. Isn’t it?



Kevin Tran was a fan-favorite character that died rather unexpectedly. As one of God’s prophets, he was privy to a wealth of knowledge and helped out the Winchesters on multiple occasions. His death left many fans rather disgruntled, to say the least. Around the end of season nine however, Kevin returns as a ghost, having attached himself to the physical possession of his class ring and returns home to live with his mother.

At this point Heaven is deadlocked and souls cannot go there. After Heaven opens again, then what? What does Kevin do? He could have stayed, but that would have been risky, since he could turn into an angry spirit. He might’ve gone to Heaven, but we don’t know. Nobody seems to know and no one has mentioned it even in passing.


At the end of season six and the beginning of season seven, everyone’s favorite angel Castiel has assumed the role of God. After absorbing the Leviathans, Castiel decides, that since God is absent from the universe, that he will be the new God, but how does an angel become God? Chuck i.e. God, was clearly still alive, albeit doing his own thing.

For the sake of argument, let’s assume Castiel became God (even though Chuck was around somewhere), how did he lose to the Leviathans? Wouldn't the God-level angel be in control of them? God locked them away originally, so if Castiel couldn’t maintain them, what did he become? Clearly stronger than any angel, Death mentioned Castiel seemed like a "mutated angel" rather than a god. So maybe Castiel only called himself God, but was really transformed into a mutated angel.



Occasionally Sam reminds audiences and Dean about everything he’s given up in order to fight monsters; college is high on the list. It’s a puzzle how long Sam actually was at college, as we get different measurements of time. The first couple episodes of season one offer up different statements; Dean says it’s been two years since he last saw Sam, which wouldn’t make sense since Sam is about to be interviewed for law school, and he’d have to have to just finished his BA, a total of four years, to do that.

Eric Kripke acknowledged the mistake, saying Sam was meant to be 20, but they aged him to 22 and forgot to change Dean's line from "two years" to "four years." Even so, there are multiple theories out there explaining the time discrepancies and no one can seem to agree, despite the show’s creator giving his opinion.


One of the most powerful weapons in the Supernatural universe, The Colt was first introduced way back in season one. Upon its introduction and subsequent stories, we learned two things: The Colt has seen many owners and it can kill anything in the universe except for five specific beings. For a time, it served as one of the weapons the Winchesters could go to if things got rough. Slowly, the gun started to get forgotten and wouldn’t see the light of day again until season 12 when the brothers do battle with Dagon, one of the Knights of Hell.

Though Dagon severely damages the Colt and Sam admits he’s not sure whether he can repair it, why isn’t he trying to repair it? A gun that can kill anything is super handy and Sam ought to at least give it the old college try!



Supernatural’s first episode jump started the rest of the series. Later, things would get explained, all we knew at the beginning was that a yellow-eyed demon had killed Mary Winchester, the boys’ mother. That set their father down on the warpath to hunt down supernatural monsters. It seems Yellow Eyes had a plan involving Sam all in the name of freeing Lilith, a chore he’d been tasked with, and also finding a child that could kill her.

However Lucifer and Michael stated that Sam and Dean were destined to be their vessels due to their ancestry dating back to Kaine and Abel, which contradicts Yellow Eye’s intentions for Sam. Audiences also forgot that Jake Talley, who decided to work for the demon Azazel, killed Sam towards the end of Season Two. There are plenty of layers involved in this plot hole and it’s a situation that’s raised numerous questions.


Season five of Supernatural was supposed to be the show’s finish. Only through a massive appeal by millions of fans that also translated into a spectacular viewership did the CW decide to keep the show going. Even so, the fifth season was also about leading up to a confrontation with Lucifer. Before the Winchesters can battle the Devil, they first had to deal with the Four Horsemen of the Apocalypse.

Each of the Horsemen had rings of power, but the Winchesters were able to cut them off and prevent them from reaching their full strength. The rings themselves turned into the key for The Cage, which locked up Lucifer. After that Dean was the last person to touch them. But what then? These are highly powerful artifacts and nobody mentions them again. Does Dean still have them? Who knows!



Supernatural is rife with death and we know when someone dies, they go to the afterlife. Typically the afterlife is either Heaven or Hell. We’ve seen both, and one of them is certainly more unpleasant than the other. Though it turns out there was also Purgatory, the space in between the afterlives. Purgatory is a nightmarish landscape that has no order or reason to it; only the especially unlucky end up there after they die.

It raises the question, what happens when you die in Purgatory? Purgatory is for the dead, not the living, so how do dead people die again? Do they respawn somewhere else in Purgatory, only to live out their undead lives over and over? Are their souls finally purged and do they go to Hell or Heaven depending on how they behaved as a human? These are all questions we never discovered the answers too.


One of Supernatural’s biggest story arcs dealt with Lucifer trying to claim Sam as his personal vessel. The younger Winchester brother goes through a lot of grief as a result, but the idea behind Sam needing to be prepared to become Lucifer’s is rather unclear. In one of the final season five episodes, Castiel mentions to Sam that for the mortal’s body to be able to handle Lucifer’s essence, Sam would have to drink a sickening amount of demon blood; more than he ever drunk before.

Castiel also says doing this strengthens the vessel to make sure it doesn’t explode, However, there is one thing not explained. While it’s true that Sam is Lucifer's destined vessel and needs to prepare by consuming large amount of demon blood, Dean, Michael's true vessel, does not. Why is that? Can you answer that mystery?



Sam and Dean are constantly on the road, but whenever time allows, we see the duo eating greasy burger or having a slice of warm pie. But how? Where do they get their money from exactly? How do they have money for things like gas, food, clothes, and the motels they’re constantly staying in? There are a few episodes where the brothers hustle people at pool in bars, but they’d have to be the best hustlers and pool players in the world in order to make enough money to support themselves.

Lest not forget, they also need money for weapons, ammunition, fake I.D.s and whatever else they need to work a case, including fancy laptops they just seem to have in possession. Do they loot bodies of victims? Do they steal and rob little convenience stores? Will anybody tell us what they do for work and money?


Garth Fitzgerald was introduced in Season Six as a rather eccentric and endearing hunter. He teamed up with the Winchesters a couple times and would make appearances up until season nine, where it was revealed that he’d suffered an accident and was now a werewolf. Sam and Dean met Garth again, and the lovely goof is living with a bunch of pacifist werewolves. After that, we never see Garth.

Season 12 featured the British Men of Letters going around hunting down every supernatural entity they perceived as a threat. Dean gives Garth a phone call, saying he ought to go into hiding. And then…? The British Men of Letters are gone and things are once more safe for benevolent supernatural creatures. Maybe Garth is living peacefully and has a family; it would be nice to know one way or the other.



Supernatural’s current season, that being season 13 at the time this list is being written, is focusing heavily on Lucifer’s son, Jack, who is a Nephilim. That is, he’s the child of a fallen angel and a human. The idea is pretty cool and Sam and Dean are currently taking on the role of his surrogate parents in an attempt to teach him right from wrong. Yet this wasn’t the first time the notion of the antichrist has been seen on the program. Back in season five, the character Jesse was introduced, claiming to also be the antichrist.

At the end of the episode, Jesse disappears and is never heard from again. There are plenty of assumptions that could be made about his whereabouts, but those are just assumptions. Where is one of the most powerful beings in the universe hiding? Does anyone, including the showrunners, even know?


This one could send theologians in an endless debate. In the universe of Supernatural, we see all kinds of gods, fairies, and even characters like Lilith. Many of them are given backstories, but plenty of them aren’t. At one point we see Lucifer kill a bunch of other gods like Thor, and it’s treated like it’s no big deal. We know for a fact that Chuck is that one true God and he has a sister.

If Chuck is God with a Capital G, then how did all the other gods come to be? Who birthed them and/or who created them? What makes a god a god specifically? Demons, archangels, and angels are explained, but other deities are casually waved off. It’s a perplexing question with no answer… at least not yet.



Reapers were an interesting addition to Supernatural lore. While the entity Death exists within the TV show’s universe, he doesn’t make a pit stop to everyone who dies. He delegates. Occasionally, if a death is big enough Death appears to reap the individual. Typically though, Death leaves the task to his Reapers.

The Reapers have gone through several questionable changes over the years, and some of them don’t make sense. Reapers began as incorporeal things who didn’t really care about the politics of heaven and hell. They merely existed to fulfill their function. Later though, and rather inexplicably, they are no longer fully incorporeal but are able to get possessed by demons. Then they got retconned once more and were revealed to be a type of angel. The Reapers’ relationship with the Winchesters is roadmap of confusion too; sometimes they’re friends, enemies, and everything in between. It’s never clear.


Several seasons ago, the Winchesters discovered there was a secret magical bunker left over from the Men of Letters, a scholarly group dedicated to battling the supernatural. They learned their grandfather was a member and that it was part of their heritage; the entire time fighting monsters Sam and Dean had simply considered themselves Hunters. In this bunker there are troves of information as the entire place is one giant library about the occult.

The British Men of Letters had their own resources and used the arcane knowledge to maximum effect. Sam and Dean haven’t done this at all. The only time they scour through the books is when they’re reading up on how to beat a specific baddie, but there’s so much wasted potential in those pages. Why they haven’t stopped to read and learn how to become even more formidable is an enigma.
