Intent on a plan of his own, Klaus hosts a strange dinner party, where he reveals another story from his family's violent past until an unexpected guest brings the party to an end. Meanwhile, Caroline is heartbroken when she is unable to stop a tragedy from unfolding.
- Seconds after Elijah (Daniel Gillies) rips the heart out of Klaus's hybrid, Elijah can tell his brother is clearly surprised to see him, which means he didn't take out the dagger to wake him up. Elijah is on him in no time.
They throw each other around the room a little. Klaus (Joseph Morgan) makes his case, pointing out he reunited Elijah with their family. Elijah isn't going for it and keeps coming. Klaus grabs a dagger out of his other sleeping brother Kol's chest and prepares to use it on Elijah. Elijah dares him to. Klaus tells him he killed their father, Mikael.
Elijah wants to know why their family are still in coffins, Kol (Nathaniel Buzolic) for over a century and Finn (Caspar Zafer) for more than 900 years. He blames Stefan (Paul Wesley), saying he holds the one thing keeping him from freeing them.
Klaus says there are things Elijah doesn't know about their past and their mother's death, but he's ready to tell him now.
But first, he puts the dagger back in Kol's chest.
Klaus checksElijah is still loyal and asks for his help destroying Stefan so their family can be whole.
Alaric (Matthew Davis) wakes up with a hangover after a night with Meredith. Sheriff Forbes (Marguerite MacIntyre) comes by, with the stake someone drove through the medical examiner's heart. Alaric recognizes it as their family set. They only found one set of prints on it: Elena's.
Sheriff Forbes doesn't think Elena (Nina Dobrev) did it. Damon (Ian Somerhalder) calls in, and thinks Klaus could have done it. Elena wonders if Stefan could have done it.
Damon gets off the phone and meets Elijah. Damon left a note in his jacket pocket before removing the dagger. "Elijah, let's get together and talk about the destruction of your brother. --XOXO Damon"
Damon asks if he knows what's in the coffin.
Stefan leads Bonnie (Kat Graham) and her mom Abby (Persia White) to the hidden sealed coffin in the caves underground. Stefan suggests they find a way to open it before Klaus finds them and kills them.
Stefan emerges from the caves to find Elena waiting for him. She asks if he killed the ME. He's offended she asked and asks why she hasn't asked Damon the same thing. The implication of him shaming her for kissing Damon is clear.
Caroline (Candice King) goes to the hospital to meet with Dr. Meredith Fell (Torrey DeVitto), Alaric's lady. Caroline's dad was being a jerk about being healed from vampire blood, so she discharged him. Meredith knows Caroline's a vampire.
Caroline reports back to Elena that Meredith seems OK. They're walking down the hall when Caroline calls her dad. She hears his phone ringing. It's coming from a supply room. They go inside and see Bill (Jack Coleman) dead on the floor, his throat slit and a knife in his chest.
Caroline rushes to him. He's beyond help. She pulls the knife out. Elena points out he has vampire blood in his system. Bill opens his eyes and gasps for blood.
Down in the cave, Bonnie explains the cave drawings her to her mom -- about a mother who loved her children so much she turned them into vampires. One of them is Klaus.
Bonnie goes through her mom's gremoire. Abby tore out the spell she used to seal Mikael in the tomb, but she remembers it. A blood knot drawing signals you need two people from a bloodline to unseal it.
Damon tries to convince Stefan to come to a sitdown with Klaus, to buy time for Bonnie and Abby. Damon thinks un-daggering Elijah was smart, since he's in full vengeance mode. Stefan doesn't think they can trust him, but the Salvatore brothers don't even trust each other right now.
Damon can tell Stefan is angry about him kissing Elena. "Just remember if it wasn't for Klaus, you wouldn't have become such a dick and that kiss would have never have happened. So get ready, and get happy, we're going to negotiate a fake truce and I don't want your attitude screwing it up," Damon says.
Caroline talks to her new vampire dad. He didn't see who attacked him. He refuses to feed, even though he knows not doing so is going to kill him.
Alaric arms up back home. Elena brought the knife that was in Bill. Alaric recognizes it as his own, which means Meredith knew where it was.
The stake used on the ME was in Damon's car, at the fundraiser, where Meredith was. Alaric plans to get the dagger to the police.
Damon and Klaus arrive at Klaus' to find he's prepared a dinner, with hot chick waitresses. Damon tries to cajole Stefan into playing nice. Stefan asks about Rebekah (Claire Holt). Klaus says he already told Elijah about killing their mother.
Caroline hasn't been able to reach Tyler. Elena isn't sure whether Meredith is involved. Caroline's mom and dad are in the house. She and Elena wait outside. Caroline wonders if Tyler could have attacked her dad. She wants to force her dad to feed, but Elena says it's his choice.
Matt (Zach Roerig) joins them and comforts Caroline.
Klaus taunts Stefan with Elena. Klaus tells them about Tatja, the originator of the Petrova line. Klaus and Elijah both loved her. Their mother dealt with her, using Tatja's blood to complete their transformation. Elijah extols the idea of family above all.
In the caves, Bonnie and her mom try a spell but Bonnie quits, accusing her mom of not trying. Abby says the spirits are angry with her for leaving Bonnie. Bonnie argues that's not true, the spirits gave her the dreams about her.
Bonnie doesn't understand how she never came back for her. Abby says there's no way she can show her how sorry she is. "Yes there is, you can help me," Bonnie says. They try again, joining hands over the coffin and chanting.
The candles surrounding them flare and the ground shakes. The coffin lid is looser. Bonnie leaves to call Damon.
There's a noise from the coffin, Abby reaches for it and the lid flies open.
Damon gets a text from Bonnie asking for more time. Damon suggests a deal: Klaus takes his coffins and leaves. Klaus doesn't want to leave Elena's doppelganger blood. He doesn't think they can protect her.
Damon goes for air.
Matt walks Elena home. At her house, the power is out.
They grab flashlights and see blood on the floor and a bloody handprint on the wall. They grab knives and follow the trail. The house shows clear signs of a struggle. Alaric is at the top of the stairs, with a knife in his belly.
He's alive. He doesn't know who did it. He tells Elena she has to kill him. As a doppleganger, she's supernatural. If he dies a supernatural death, his ring will bring him back. He's lost too much blood to make it to a hospital. Elena takes a deep breath and drives a knife deep into Alaric's gut. (She can't just let him die because if a human attacked him, he'll just be dead.)
Stefan thinks Klaus's motivation for the evening was to drive a wedge between him and his brother. Klaus points out Stefan's doing a good enough job on his own.
Klaus presents his counter offer: Elena's future happiness. He wants to set Elena up with Matt, so they'll have children, whose blood he can use to make more hybrids. Stefan walks over and shakes Klaus's hand. But he tells him no deal.
Klaus grabs Stefan's arm and sticks it in the fire. Elijah prevents Damon from helping. Klaus orders Damon to bring the coffin and assigns Elijah to go with him, and promises to hand over their family when Elijah returns.
Caroline checks on her dad, who is not doing so well. He asks her to call Steven when it's over.
Caroline tries to convince him to change his mind. He won't go against his beliefs. She asks how he can hate who she is. He tells her that's not true. She's strong and good and just who he and her mom hoped she'd be. She begs him not to leave her. He says parents aren't supposed to outlive their children.
Back at Klaus's, Stefan dares him to finish him already. As Klaus is wondering where Stefan's fight has gone,
Elijah comes back in the room with two daggers on a tray. In walk Kol and Finn, un-daggered. Finn immediately drives a dagger through Klaus's hand.
Rebekah joins the party, stabbing Klaus in the gut. "This is for our mother," she says.
Finn holds Klaus. Elijah tells the Salvatores they're free to go. "This is family business," he says.
Caroline holds her dad's hand as he lies in bed.
Elena waits for Alaric to come back. Caroline called, her dad died. Elena asks Matt to stay with her, she can't lose any more family. Matt hugs her.
Stefan and Damon walk home and Stefan admits un-daggering Elijah was a good idea. He points out Damon could have left him there and had Elena to himself. Elena calls Damon and he ignores her call.
"I love her, Damon," Stefan says. "So do I," Damon says.
Elena talks to Sheriff Forbes. She checked -- Meredith was in surgery when Alaric was attacked. He's the third member of the Founder's Council to be attacked and they have no suspects.
Alaric sputters back to life.
Damon and Stefan go into the cave and find Bonnie knocked out. The coffin is open and empty.
Klaus faces his siblings' rage. Rebekah tells him they're leaving him, right after she kills Elena, leaving him alone with no more hybrids. He rages he's a hybrid and can't be killed, and has nothing to fear from any of them. Elijah says he will when they have the coffin.
The door opens. They all stand in stock. It's their mother Esther (Alice Evans).
She walks over to Klaus. He cowers. "Do you know why I'm here?" she asks. "You're here to kill me," he says. "Niklaus, you are my son, and I am here to forgive you," she says.
She addresses all her children: "I want us to be a family again."
