A new fan theory about Stranger Things season 5 has a new take on an important line from throughout the series, which could be the key to stopping Vecna. Stranger Things season 5 will end the long-running Netflix series, with Eleven and her friends in Hawkins getting ready to fight Vecna and the Upside Down. Stranger Things season 4 became the most-watched series on Netflix, meaning there's plenty of intrigue about what the final season will hold.One fan, willow the wise on Twitter, believes an important line from the show could explain how Eleven and her friends will defeat Vecna in Stranger Things season 5.

The theory, which can be read by clicking the post above, states that, despite the line "friends don't lie," being an important part of Stranger Things, every character was introduced with a lie in season 4. Willow posits that characters' lies being revealed and their ability to work through them together will help defeat Vecna.

How Will Vecna Be Defeated In Stranger Things Season 5?

Much of Stranger Things season 4 focused on characters learning to come back together after being apart for a long time, both physically and emotionally. One key relationship that was repaired was Mike and Eleven, who didn't have as strong a connection following Eleven's move to California with the Byers family. At the end of Stranger Things season 4, Mike tells Eleven he loves her, which gives her the strength to push back against Vecna.

Mike's honesty pushing Eleven to defeat Vecna lends to willow's theory about how the Stranger Things villain will be defeated once and for all. Eleven might beat Vecna in Stranger Things season 5 through her friendship with every other major character in the show. Everyone else could also assist her by being honest with one another, somehow using the power of their true feelings and beliefs to help destroy Vecna for good.

While it's unclear how Vecna's defeat will come to pass, the theory about lies and truths means honesty could be a hidden weapon the group could use to win. The battle is likely to be difficult due to Vecna's abilities and his control of the Upside Down. However, with Eleven leading the charge against him, it's possible Stranger Things season 5 will see truth prevail, thus bringing Vecna's reign of terror over Hawkins to an end.
