Damon croaks, "His emotions have been shut off. He can't care."
MtVVS: "Really, his link to Klaus is so strong that he would let his own brother die?" When MtVVS tells Damon that Stefan and he are dead ends, he shoves his hand further in Damon's chest.
Stefan grabs MtVVS's arm and says, "Wait. I can bring him back. I can lure Klaus back to Mystic Falls."
Pleased that Stefan has been inspired to find a loophole, MtVVS pulls his hand out of Damon's chest, with a disgusting squicky sound. He tells Stefan, "Get Klaus back to Mystic Falls, and I will gladly drive a stake through his heart. Fail, I'll drive it through yours." Commercial
In A Cavern: Elena meets up with Alaric and Bonnie at the cave. He's putting up his sticky-note labels: vampire, werewolf, slaughter, mayhem, etc. Elena identifies the etching of the white oak, which had been the only way the Original Vampires could be killed. Alaric notes they already knew the tree equals a weapon of some sort. He's still not sure about the witch symbol combined with what looks like a bleeding heart. They're upside which often signifies death.
Looking at the drawings, Elena says, "Mikael killed the witch by ripping out her heart. She puzzles over another symbol and asks about it. Bonnie tells her they haven't gotten that far, yet. The symbol looks like a combination of the werewolf and vampire petroglyphs. A lightbulb goes on over Elena's head. "Oh my God. Rebekah doesn't know the real story."
Mossy Manse: Rebekah is pouring herself a drink when Elena walks in. Rebekah wants her to leave, but Elena asks how she knows Mikael is the one who killed Eloise Hawking. Rebekah says "Nik" witnessed it and told her. Elena: "He lied to you. [...] The cave where you carved your name is covered in symbols -- the story of your family -- how your parents arrived. How they made peace. The spell that turned you into vampires, and this." Elena has laid out a picture corresponding to each element above. The picture for this is the hybrid petroglyph. She shows Rebekah the symbol for her mother. Beckster says, "Her necklace?" Then Elena shows her the death story. She narrates: "The hybrid killed the Original Witch -- not Mikael, Klaus."
