The Last Dance
The Last Day
KNOW THY ENEMY— Stefan and Damon are furious when they discover that Elena has defied them both to make a new ally and take control of the plan to out-maneuver Klaus. Disagreeing over how they should protect Elena leads to growing tension between the Salvatore brothers. Meanwhile, Stefan has his hands full trying to keep a confused and frightened Jenna safe. Flashbacks to 1491 reveal Katherine’s introduction to Elijah and Klaus along with the origin of the moonstone curse. Elena learns shocking new information about Klaus and his motives.
|Elena sits as Elijah suddenly comes back to life and his first word is "Katerina" when he sees her, thinking at first that she is Katherine. Right into the first flashback set in 1492, England, where Trevor introduces Katerina to the Lord Elijah. In present day, Stefan realizes both Elena and Elijah are gone.
He gets Elena on the phone and she tells him that she needs time alone with Elijah and Stefan needs to respect her decision. She gives Elijah the dagger back to show that he can trust her. After a quick stop at the Lockwood mansion for clothes, Elijah continues to reveal history and drops the bomb that he and Klaus are brothers. "I'm a bit behind on the times, but I believe the term you're searching for is OMG," Elijah says.
- Antagonist: Klaus
- On March 1, Dawn Olivieri tweeted part of the script that was in fact not supposed to be on there, as it was a leak and the producers do not like spoilers to be ruined. This is the reason why the image was removed shortly afterwards, and the original is no longer on Twitter.
- This episode features Klaus' first appearance in his own body. It also features a re-appearance of Trevor in flashbacks. 
- This is the seventh flashback episode.
- Caroline, Bonnie, Jeremy, Tyler and Matt don't appear in this episode.
- This is the first episode of Season Two to feature only five main characters (Elena, Stefan, Damon, Jenna and Alaric).
- This is Greta Martin's first appearance on the show.
- Jenna learns the existence of vampires in this episode. With this, all main characters now know the truth or at least part of the truth of the Salvatore Brothers.
- Elijah reveals 3 shocking secrets:
- He and Klaus are half-brothers.
- Klaus is a vampire-werewolf hybrid.
- The Sun and Moon Curse is fake. The real "curse" is that the witches suppressed Klaus' werewolf side so he wouldn't be an over-powerful hybrid with all the powers of both species and none of their weaknesses. Werewolves can mate with each other or humans so Klaus would have the ability to procreate and hence the ability to sire an unstoppable un-killable hybrid race destroying the witch enforced balance between vampires, werewolves and humans.
- Elijah's and Klaus struggle over Katherine affection's clearly mirrors the one between Stefan and Damon. History Repeats itself.
- There is a bit of foreshadowing - when Elijah meets Katherine for the first time he says "Forgive me. You remind me of someone". We later find out that this "someone" was Tatia.
- When Klaus says "Niklaus is the name my father gave me. Please. Call me Klaus" he is indicating that wants to distance himself from his father by rejecting the name he was given.
- In the "Previously On The Vampire Diaries" section, they foreshadow the revelation of Klaus being the subject of the curse himself, rather than vampires and werewolves in general, when just after talking about the Sun and Moon Curse, Rose says "Klaus is the real deal". This particular part was possibly deliberate as "Klaus is the real deal" here may mean both him being the most powerful vampire around and him being the subject of the curse rather than a Sun and Moon Curse.
- Alaric meets Katherine for the first time, but he mistakes her for Elena.
- This episode had 2.700 million viewers in the USA.
- When faced with two terrible choices, Elena takes the third option and makes an alliance with Elijah.
From sheknows.com, the meaning of the name Klaus reflects the character's personality: People with this name tend do initiate events, to be leaders rather than followers, with powerful personalities. They tend to be focused on specific goals, experience a wealth of creative new ideas and have the ability to implement these ideas with efficiency and determination. They tend to be courageous and sometimes aggressive. AS unique, creative individuals, they tend to resent authority, and are sometimes stubborn, proud and impatient.
- Elijah (To Elena): "Yes. Klaus is my brother."
- Elijah (To Elena): "I believe the term you're looking for is.... OMG."
- Klaus (In Alaric's body): "Do you believe in vampires, Jenna?"
- Klaus (After returning to his body): "That's more like it."
- Elijah (To Elena): "I need some air. I'm still feeling a tad dead."
- Elijah (To Elena about Klaus): "I helped him because I loved him. That's changed. Now he must die."
- Katherine (To Elijah in 1492): "True love is not real unless it is returned."
- Katherine (To Elijah in 1492): "Life is too cruel. If we cease to believe in love, why would we want to live?"
- Klaus: "The full moon is tomorrow, brother. After all these centuries, it is finally time."
- Elijah: "I have been to see the witches. They believe they may have found a way to spare the doppelgänger."
- Klaus: "What does it matter if she lives or not? She's a means to an end, that is all."
- Elijah: "What, she should die for your gain?"
- Klaus: "She's human. Her life means nothing."
- Elijah: "I beg you to consider this."
- Klaus: "Are you so foolish as to care for her?"
- Elijah: "Of course not."
- Klaus: "Love is a vampire's greatest weakness and we are not weak, Elijah. We do not feel and we do not care."
- Elijah: "We did once."
- Klaus: "Too many lifetimes ago to matter. Tell the witches not to bother. The sacrifice will happen as planned."
- Stefan (To Elijah): "I'm sorry for the part that I played in your death. I was protecting Elena. I will always protect Elena."
- Elena (To Jenna): "I should've told you. I thought that if you didn't know you'd be safe. But then things got so out of control and everything I've done to keep you out of it all blew up in my face."
- Elijah (To Elena): "Your phone wοn't stop it's incessant buzzing. Answer it."
