With The Winchesters finally bringing fans back to the world of Supernatural, fans of the series are excited to once again catch Winchesters taking part in the family business. It's even been fun to see Dean Winchester picking the music back in the Impala.

Yet fans are rightfully worried that the show might make some of the same mistakes that Supernatural did. After all, Supernatural had many plot holes that never had any resolution, and they really do eventually deserve to be revisited and explained.

The Fight Between Michael And Lucifer

The fight between Michael and Lucifer was one storyline that the show had spent over a decade preparing for. Yet, when it actually came, it's not nearly as terrifying as fans expected. Reddit user Various_Permission47 comments, "It was pathetic. In season 4/5 it was supposed to destroy half the world and it didn't even wreck the building they were in."

Michael and Lucifer were two of the most powerful characters in Supernatural, and their endings were as lackluster as it was boring. If the show wanted to revisit them, they should have caused as much damage as they were meant to, even if it meant an apocalyptic future.

Jacob Pond's Vengeance

After murdering Amy Pond, a kitsune who was killing to protect her son, Dean found that her son swore that he would return the favor and kill him. It was clearly something that was going to come back to bite Dean, but it never actually ended up materializing.

"He had a powerful, meaningful story and the creators just dumped it," writes Redditor mizejw. Instead, Jacob became one of Supernatural's many forgotten characters. It was incredibly disappointing and, if the show needed to kill off Dean, it should have used Jacob instead of a rusty nail.

Dean And Sam As Forgotten Fugitives

As hunters, Dean and Sam were rarely on the right side of the law. There were many times when the two of them struggled to avoid prison, and sometimes, they even failed to. Yet for some reason, they always managed to come back without anyone even recognizing two of the FBI's most wanted.

"The amount of times Sam and Dean are country wide fugitives then next season act like nothing happened," says Redditor OblivionArts. It's a major plot hole, as they should never have been able to interact with law enforcement without a hefty prison sentence.

Adam In Hell

The Winchesters were all about family, or at least, they were all about the family that they cared about. Their half-brother Adam rarely actually won the same protection. Redditor Various_Permission47 thought that "Leaving Adam in hell" was ridiculous. They further elaborate, "And let's face it, they did not make best efforts to retrieve him."

Given that Sam managed to escape from the cave, the brothers knew that it was possible. Yet they left Adam to suffer in endless torment for no reason at all. The Cage was the worst thing to happen to Sam, so letting Adam stay there was just needlessly cruel.

Forgetting Christo

Early on in Supernatural, the brothers could simply use the word "Christo" to force demons to reveal themselves. Eventually, though, they just forgot about it. Instead, demons came out of nowhere to surprise them constantly, leaving the brothers struggling to figure out who to trust.

"If they didn't wanna use it anymore, they could have filled it in by saying the demons for some reason where no longer affected," says Reddit user Die-alreadyy. At the very least, the show should have done something to acknowledge the absence of "Christo" rather than just pretending that the brothers forgot about a major hunting tool.

Jack Being So Powerful

While Jack was one of the best Supernatural characters, he never should have been as powerful as he was. Reddit user DisastrousWelcome710 argues, "Sure, he got turned into some cosmic sh*t and was able to "absorb" power from all that's around. But God even says after they tell him their plan that it was the first time he doesn't know what's next. Meaning he knew what was going to happen, and he let it happen anyway?"

The fact that Chuck would allow the character's creation who could outright defeat him was ridiculous. If any character was going to defeat God, it should have been the rebellious Michael paired with Lucifer, which is much more believable than the sudden arrival of a ridiculously powerful Nephilim.

The Forgotten Tools

Supernatural featured hundreds of different tools that could kill demons, vampires, werewolves, and more. Yet Dean and Sam rarely rely on the many piles of information that the Men of Letters offered them. "The massive amount of lore, weapons and spells that they collect that would be massively useful and completely ignored," says Reddit user benadunkcamberpatch.

Dean and Sam should have been recording the tricks that they found all along, while also using whatever tools they could find along the way. Their priority after discovering the Men of Letters outpost should have been learning everything they could. Instead, they just shrugged.

The Disappearance Of The Anti-Christ

Another forgotten character who should have had a bigger impact was one who could have destroyed the world. According to Reddit user dog5and, the worst plot hole was "the complete and total absence of Jesse Turner, the antichrist kid." A half-demon, who was meant to aid Lucifer, Jesse just never appeared again.

Jesse only appeared in one Supernatural episode, yet he could have been so much more. After Lucifer's return, he should have found the boy and used him in the fight against Michael. Instead, Jesse's destiny was completely forgotten, and the show just moved on without a care.

Soulless Sam

While the presence of Soulless Sam was fascinating and offered an interesting break for the show, it didn't actually make any sense. "How did Cas not realize Sam's soul wasn't there when he rescued him!?! Even if it was a mistake, how did he not realize for months that Sam was soulless?" writes a now-deleted Reddit user.

Still, while it was a serious plot hole, it was also hilarious enough that many fans were willing to overlook any problems with the plot. Yet The Winchesters has a great chance to showcase whether it was actually possible to see if a soul was absent from a body, even if it can't have characters like Castiel appear to explain it.

The Forgotten Queen Rowena

Ruling Hell had been a lasting plot for the show's entire run, so it really deserved more attention than it received. "A plot line of Rowena being the queen of hell and some kind of insurrection brewing that was just left dangling that really bothered me," says Reddit user dog5and.

​​​​​If there was to be an insurrection, they should have shown it and clarified who would win. While Hell has never been outright stable, fans were invested in the realm's political structure and deserved to see more. If Supernatural is looking for more spin-offs, a political drama about Hell could even be a great way to resolve the plot hole by showing Rowena consolidating power after the plot was dropped.
