Whether fans love the unnerving moments when Katherine shows up or are shocked by some big character deaths, there are several plot twists on The Vampire Diaries that fans are talking about on Reddit.

Katherine And Elena Are Linked

When discussing plot twists on this juicy show, many of them involve Katherine, especially since Katherine survives many TVD moments when it seems like she should be dead.

Reddit user Mariachrisma loves the season 2 episode "Masquerade" and wrote that their favorite plot twist is "When katherine linked herself to Elena! Favorite episode of all time!" It's always scary to think about what an impact Katherine's actions have on Elena and what horrors await.

Damon Murders Tyler

Tyler is a fan favorite character on the series, whether viewers like seeing his romance with Caroline or the moment when he learns that he's a werewolf.

For Reddit user InevitableTone65, the "Biggest twist" was "when Damon killed Tyler. I was so shocked when that happened." Even though this is a fictional world where anyone can be killed and also return, it's still a huge deal when it takes place.

Katherine Appears In The Season 1 Finale

At the end of the season 1 finale "Founder's Day," Katherine makes everyone think that she's Elena and hurts John and gets involved in Elena's love life. This shifts the whole tone and helps viewers see the big impact that Katherine will have on Elena's future. Nothing will ever be the same again in Mystic Falls.

Reddit user strawbebb loves the plot twist of "Katherine’s introduction when she pretended to be Elena." Reddit user Olea loved this moment too, writing, "When Elena kissed Damon back it made my jaw drop and then it turned out to be Katherine and it was so masterfully done."

The Sun And Moon Curse Isn't Real

While there are some great couples on The Vampire Diaries, the rules and curses that run the vampire and werewolf worlds are also a fun and fascinating part of the series.

One Redditor likes "The sun and moon curse being a hoax" and called it a "clever deception." Fans learn that this curse means that the sun hurts vampires and werewolves turn if there's a full moon and nothing else. It's amazing to hear that Klaus came up with this curse and that it's not real at all.

Damon And Stefan's Mom Isn't Actually Dead

While some characters on The Vampire Diaries stay dead, others come back, which is what happens to Lily Salvatore.

Reddit user ZapooDaWizKid mentioned the plot twist of "Stefan and Damon's mom being alive." Fans discover in the season 6 episode "Let Her Go" that when Bonnie sees a 1903 prison, she finds Lily there, which is a huge revelation and hard to believe after thinking that she was gone for so long. This means so much since fans know that Stefan and Damon have suffered a lot and all they want is family, love, and compassion.

Katherine Can Leave Her Tomb

When Bonnie, Damon and Stefan trap Katherine in a tomb, Elijah compells her and says that she won't be able to get out until he decides that she can. When Elijah dies, that changes things.

One Redditor likes that "Putting a dagger in Elijah's heart actually released Katherine from the tomb." This is an exciting moment in the series as Katherine is always one of the biggest dangers to Elena's happy life and at this point, fans can't wait to see what happens next.

Stefan Dies In Season 5

Fans know that not everyone stays dead in The Vampire Diaries, but it's still terrifying seeing Stefan die in the season 5 finale "Home."

Reddit user greasyeggplant said that "Stefan's death in S5" is a favorite plot twist. When Julian removes Stefan's heart, Caroline realizes that Stefan is dying and is totally freaked out, which is exactly how fans feel while watching this.

Silas Is Stefan's Doppelgänger

When it comes to underrated The Vampire Diaries plot twists, Stefan having a doppelgänger is definitely up there. This creates a lot of excitement on the show as it changes things for Stefan forever.

Reddit user hdjdjdkenendn enjoys this storyline and wrote, "To this day my favourite plot twist will always be the reveal of Silas." The fan wrote that learning that "Silas is actually Stefan’s doppelgänger" was amazing, especially since no one knew that Stefan had one.

Caroline Is Pregnant With Twins

Caroline has quite the epic love life on TVD, including her relationship with Alaric in season 7. While it's smart that Alaric realizes that Caroline loves Stefan, Alaric is still heartbroken and it's a tough storyline to watch.

One Redditor replied in a thread about the "biggest plot twists" in the series and said, "The twins being transferred to Caroline." While Caroline as a vampire can't be pregnant, Caroline begins carrying Alaric's twin babies. It's an awe-inspiring moment.

Bonnie And Damon Die

Reddit user greasyeggplant also mentioned the plot twist of "Damon & Bonnie's death" after viewers learn that Stefan is gone.

This is definitely a thrilling and terrifying way to kick off season 6. Elena is grieving at college and at the conclusion of the episode, Bonnie and Damon are eating a meal in a mysterious location. This is one of the best ways that The Vampire Diaries ends an episode as it's a smart cliffhanger.
