Audience: *Feels vindicated and yet oddly ripped off*
Elijah goes to Mossy Manse, to proposition the Salvatores. Not like that. Either they stop Esther, or Rebekah will kill Elena. The only apparent way to stop Esther is to break her tie to all the Bennett witches, ever. Bonnie and Abby are that tie. Kill them, or Rebekah will kill Elena.
Elijah: You have until six minutes after nine to find them.
Damon: Oh, how super specific of you.
Elijah: Full moon's at 9:07 PM, asshat.
Down in the caves, Rebekah takes pictures of Elena, to send to Damon and Stefan.
Elena: Hey, does her phone work down here? My phone doesn't. I bet my old phone would have. I HATE YOU STEFAN!
Rebekah: And I hate you so much, Elena, I'd almost be glad to die, just to kill you, you little, literal backstabber. Shit down and shut up.
Elena Haters: Marry us, Becky! Elena really needs to die in a fire.
Back at Mossy Manse, Damon finds Stefan mooning over an unopened bag of blood. Our beautiful Brothers Salvatore try to brainstorm. Damon's willing to kill Bonnie and/or Abby, if worst comes to worst. Stefan is more hesitant. Damon then suggests a "less diabolical plan." If they dagger one of the Original vampires, that should disable all of them (except Klaus), and will allow the Salvatores to save their girlfriend. They get Ric and Caroline to help. Klaus and Kol are already at the Grill, so Caroline shows up to distract Klaus. Ric daggers Kol. Back in the caves, Rebekah falls to the ground and starts to desiccate, as though she too had been daggered. Elena runs.
Meanwhile, outside the Which House-Witch House, Esther has drawn a pentacle. She has the self-loathing Finn at the center of it. Bonnie and Abby are there. Esther explains that since she cast the spell that made her children vampires, she can unvamp them with this spell. Once they're human, they're killable. She praises Finn for his brave willingness to serve as her sacrifice. Finn says, "It's not a sacrifice. It's a gift." When Alaric daggers Kol, as mentioned above, Finn collapses and starts to desiccate. Esther says something has gone wrong. Gee. Ya think?
Outside the Grill, Klaus is trying to chat up Caroline. It's a great scene. The chemistry between Candice Accola and Joseph Morgan continues to dazzle. When Klaus senses that Kol has been daggered, I suspect the linking spell is what tips him off. He finds Ric, Mere, Stefan and Damon dragging brother Kol out behind the Grill. Klaus quickly undaggers him. Alaric is injured in the scuffle. Damon tells Klaus about Esther's plan to off him and his siblings. Kol comes back to life, almost immediately. Elijah arrives and stops Klaus from killing the Salvatores.
