The scene opens back down in the Lockwood tunnels. Alaric shows Elena the cave markings. Damon still can't get in. Alaric deciphers some of it, including depictions of a werewolf that pre-dates the Lockwoods. There are names in a Viking script. One name is Nicklaus, then Elijah and Rebekah. Flash back to ye old times, Rebekah is carving in the stone and Klaus complaining. They're both afraid of their father. Back in the present, they realize the names have been there long before the founding of Mystic Falls. Damon suggested it could be an elaborate Klaus ruse, but the other name they found made them think otherwise: Mikael who is Klaus' father. Alaric snaps photos and studies them later at Damon's. They try to sort out how Mason's ghost saying the cave contained a weapon against the originals squares with Mikael being listed. Elena decides to go to the source.
She goes to school to talk to Rebekah. She shows Rebekah the cave etching and asks why she and Klaus have spent 1,000 years running from their father. Elena threatens to wake Mikael, citing the location of his tomb to prove she knows where it is. Rebekah warns her if they wake him, they're all doomed. In Ye Olde times, Elijah and Klaus practice sword fighting. Klaus wins and disarms Elijah. Their father Mikael arrives with their mother and disapproves of the tomfoolery. He takes a sword and taunts Klaus for playing around. His dad takes him on with a sword and quickly disarms him. He holds a sword to his son's neck and calls him impulsive. "Some days it's a miracle you're still alive, boy," Mikael taunts him. Alaric looks over the etchings and deciphers the symbols. He finds one for vampire. Elena calls Damon and tells him she thinks Rebekah will spill eventually, when their "mean girl power struggle" is over. "A thousand year old vampire I'm sure has learned the art of patience," he says. "She's a 1,000 year old vampire who's joined the cheerleading square.
There's a whole different set of rules at play here," Elena tells him. Meanwhile, Damon checks on Stefan in the jail cellar. "It's Family Day at Vampire Rehab," Damon says. Damon tries to talk to his brother, but Stefan is morose and pouty. Damon breaks his chains, says to hell with the Lexi plan, and suggests they get a drink. Elena visits Rebekah at the Salvatore place, where she has compelled a group ot teenage girls to model Homecoming dresses for her. She threatens to kill one until Elena picks a dress. Elena capitulates. Rebekah lets them go, and then warns Elena that she will give her information on her own terms. Bonnie brings Alaric the necklace that wouldn't die. He consoles her about Jeremy being an idiot. Then he shows her a carving that matches the emblem on the necklace. The symbol is repeated across the wall. Based on the origin Bonnie's grandmother told her for the necklace, he thinks he knows what the symbol means: witch. Back at the Salvatore house, Rebekah tells Elena that her family came to America, long before it was America, to escape a plague.
Her mother heard from a witch about a land where everyone was healthy. They came and lived among the werewolves for 20 years, during which time Rebekah was born. Once a month they'd retreat to caves and wait out the howling. Rebekah admires necklaces hanging in a witch's hut. Elena's necklace burns her. The witch warns it's not Rebekah's to touch. In another flashback, Klaus comes up shouting for help and carrying his brother Henrik. They snuck out to watch the werewolves turn. Henrik is torn to shreds. The witch tells their mother Esther that Henrik is gone. That was the beginning of the end of peace with the werewolves, and one of the last moments her family had as humans. In the present day, Damon calls Elena and tells her he went "off book" with Stefan. They're walking into a bar. Damon orders a whiskey and compels the waitress to let Stefan feed off her. She offers her arm and Stefan bites down right at the bar. Later at a table, Stefan plays quarters with shot glasses. Damon loses.
During this, Stefan says he's worse than Elena, trying to get to him with brotherly bonding. Damon likes living on the edge, but says Stefan goes too far over it. Back the Salvatore house, Rebekah toys with Elena, who gets fed up and pretends she's ready to leave. Rebekah tells her the necklace wasn't Stefan's to give. She says the original witch is the one, who turned them into vampires. In another flashback, Rebekah listens as Esther and Mikael beg the witch Ayana to ask the spirits for help fighting the werewolves. Being a vampire wasn't meant as a curse, it was a weapon. Ayana warns them what they're talking about is a plague and the spirits will turn on them. Mikael tell Esther it's in her hands. In the present, Rebekah explains to Elena that her mother was also a witch. The witch of the original family. The original witch. Rebekah isn't a witch. She explains her mother didn't turn.
Her mother called upon the sun for life and the ancient white oak tree, nature's sign for immortality. Mikael offered his children wine laced with blood, and then he killed them. "And he wasn't delicate about it either," Rebekah says. In another flashback, Rebekah and Klaus wake up by the fire, bleeding. Their father brings in a compelled village girl and slits her arm for his children. He forces them to drink. In the present, Rebekah says the witch Ayana was right about the consequences, for every strength there was a weakness, like getting burned by sunlight. Her mother found a solution. In a flashback, neighbors were able to keep them out. Flowers at the base of the white oak burned them and prevented compulsion and the spell decreed that the tree that gave them life could take it away. So they burned it to the ground. In the present, Rebekah explains that the worst part was the hunger for blood. She feeds ravenously on village people. "And with that, the predatory species was born," Rebekah says.
Meanwhile, Damon notices Stefan over-feeding at the bar and slows him down. Stefan asks again what Damon's agenda is. He wants to remind Stefan what it's like to not just be Klaus' little bitch, he explains. Stefan says there's no point because Klaus can't be killed. Someone approaches and offers to help. It's Mikael. At the Salvatore house, Elena wants to know why Mikael started hunting Klaus. Rebekah explains when Klaus made his first kill, it triggered his werewolf gene. And Mikael knew his wife had had an affair with a werewolf villager. Esther put the hybrid curse on to suppress his vampire side, and shunned him, but Mikael couldn't get over it. Mikael's greatest weakness was his pride and it was heightened after he turned. He went on a rampage and killed half the village, then he came home and killed his wife. He ripped her heart out as Klaus watched, Rebekah says. Afterwords, Mikael took off in a rage. Nick stayed behind to bury their mother.
Rebekah, Klaus and Elijah promised to stick together forever. Elena points out that Klaus locked her in a coffin for 90 years. Their emotions are heightened as vampires. She's stubborn, Elijah is moral and Klaus has no tolerance for those who disappoint him. Rebekah says as an immortal, she needs her brother. The alternative is an eternity alone. She knows Elena wants Klaus dead, but warns her if she comes after him, she'll rip Elena apart. At the bar, Mikael quizzes Stefan on Klaus, but Stefan says he's compelled and has been told not to talk. Mikael reaches into Damon's chest and grabs hold of his heart. He asks Stefan again, but Damon says Stefan's emotions have been shut off. Mikael's about to give up on Stefan and kill Damon when Stefan says he can get Klaus back to Mystic Falls. If he does, Mikael will kill him; if not, he'll kill Stefan. Meanwhile, Alaric and Elena take Bonnie down to the cave. He puts Post-its up with translations.
They see the white oak tree the originals burned down. There's another symbol with the witch symbol and what looks like a bleeding heart. Two of the symbols are connected. Elena remembers that Rebekah said Mikael killed the witch by ripping out her heart. Elena figures out the symbols and realizes Rebekah doesn't know the real story. Elena goes back to Rebekah's. She asks how she knows how her mother died. Klaus told her their father did it. Elena shows her the carvings. She shows her the symbol for hybrid and the one for witch and the story of her death. It involves the hybrid symbol. The hybrid killed the original witch. Elena points out that his mother put the curse on him, so he'd be the only one of his kind, and then she rejected him. Klaus was angry. Elena says he lied so he wouldn't lose Rebekah. Elena pleads with Rebekah to do something, saying Klaus has had a hold on her family for 1,000 years and now has a hold on everyone. Rebekah screams at her to stop talking and grabs her, vamping out.
Then she breaks down sobbing. Outside the bar, Damon congratulates Stefan on his breakthrough of emotion to save him. Stefan haughtily says he didn't do it for Damon, he did it for himself. When this is all over, he plans to leave everyone. Damon says he couldn't just leave Stefan to rot in the cell. Stefan taunts him that his humanity is showing. Damon decks him. Stefan gets up and Damon body slams him. He tries to get up and Damon trips him hard. He walks away. Rebekah breaks down alone. Elena comes home to find Damon waiting for her. She doesn't have the energy to yell at him for letting Stefan out. Damon tells her they got Mikael and the plan is in motion. Elena tells him they might have Rebekah on their side, too. Elena describes Rebekah as a girl that lost her mom too young who loves blindly and recklessly, even if it consumes her.
Elena realizes how familiar that sounds. "When all is said and done, there's nothing more important than the bond of family," she says. Damon suggests she remind Stefan of that. Elena thinks Damon will be the one to save Stefan from himself, not because he loves Elena, but because he loves Damon. She curls up and shuts the lights off. He watches her fall asleep.
