Have you ever watched the hit TV show Supernatural? If you have, I'm sure you've noticed a few plot holes and unanswered questions throughout the series. Let's take a closer look at some of these puzzling occurrences and try to make sense of them.

In one episode, the characters find themselves in an alternate world known as the "French Mistake." It is revealed that every alternate-world character is a variant of the prime universe person. However, there is one version of Sam who is missing. It's as if he disappeared and was replaced by the prime universe Sam. This raises the question of what happened to the original Sam in that universe.

Another puzzling aspect of Sam's story is his lack of contact with his college friends. Sam claims to still be in touch with them, even while traveling with Dean, but it seems that his friends have disappeared from his life. It is later revealed that these friends were actually demons posing as Sam's friends, but this revelation comes years after Sam severed ties with them. It leaves us wondering why he cut off contact with his friends in the first place.

In another episode, Sam and Dean discover that the Leviathans have contaminated the food supply to make people dumb and easier to consume. However, Sam is seen eating processed foods without any problems, even though the entire country's food supply is contaminated. It's unclear how Sam managed to avoid being affected by the tainted food.

One of the most mind-boggling plot holes revolves around Sam's body. When Sam jumps into Lucifer's Cage to save humanity, his body is left behind while his soul spends over a century in Hell. According to the show's previous explanation of Hell, Sam's body should have been destroyed. Yet, somehow, his body remains intact. How is this possible?

Another plot hole involves Sam's lust for demon blood.

For two seasons, this was a significant arc for his character. However, after returning from Hell, Sam seems to have completely overcome this desire, and it's never explained how or why he was able to do so.

Sam's decision not to reunite with the alternate version of his brother, Dean, is also perplexing. Why would Sam choose to spend decades mourning his brother when he had the chance to connect with an alternate version of him? It doesn't make sense.

There's also the issue of Sam supposedly turning evil. It was hinted that this would happen after Sam was resurrected, but apart from one instance of shooting someone, he never displays any evil tendencies. It leaves us wondering if the show forgot about this plot point altogether.

Remember when Sam spent over a century in Hell with another Winchester brother, Adam? Well, after Sam regains his memory of Hell, he seems surprised to learn that Adam is still alive and claims he didn't help him because they were unsure of his condition. But wait, Sam was there with Adam the whole time. How could he not know?

Lastly, when Sam cures Dean of being a demon, he should technically die due to the pending trial that involved curing a demon. But instead, Sam survives without any repercussions. It raises the question of why the intended spell to seal Hell wasn't completed.

These unanswered questions and plot holes in Supernatural may leave fans scratching their heads. While some may argue that they are simply mistakes or oversights, others believe that they add to the show's mysterious charm. Regardless, they will forever be intriguing aspects of the beloved series.
