On Friday night’s episode of The Originals, the Mikaelson brothers have to put aside petty differences to save their sister from her abductor.

Lucian marches Vince and Freya through the woods, they’re in Mystic Falls. Lucian made a deal with the ancestors to kill the Mikaelsons in exchange for Vince’s help.

Lucian brings them to the site where Esther created the Originals. He means to replicate the spell to make himself into something better. Vince will do the spell while Freya is there to give her blood.

Davina and Kol go to a bar to meet Vincent, but he’s not there. Davina senses something isn’t right. She finds a video message from Vince telling her about the abduction. He asks for her help tracking the connection between Finn and Vincent. He leaves Davina a vial of his blood.

Kol is argumentative with Finn. Davina asks for his help with the spell. Finn and Elijah will work together to track Freya down.

Klaus tells Hayley that Lucian has Freya. She tells him to go back and head up the hunt. He says he wants to stay and help her hit up all 10 Kingmaker offices.

Lucian forces Vince to start the spell. Lucian dumps an unknown liquid into the spell pot. He also puts in the white oak bullet.

Davina does a tracker spell on Vince’s blood and narrows the area down to Northern Virginia. Kol realizes they’re going to Mystic Falls. He needs to get a dark object from Cami, who he threatens to harm. Davina says Cami is her friend and they’ll go together.

Freya accuses Lucian of faking the prophecy. He says he found it and realized his rise would be their downfall.

Elijah and Finn rush to Mystic Falls. Finn tells Elijah that being daggered for decades is different than centuries. He could feel the passage of time as endless days in despair.

Cami has trouble finding Kol’s dark object. He threatens her and his eyes change. Davina tells him to get out. Cami tells Davina that she saw that same look in her uncle and thinks Kol is cursed too. She gives Kol’s bowl to Davina.

Elijah tells Finn he was daggered because he was a threat to their survival. He despised what they became and was afraid of it. Finn says every time he closes his eyes, he goes back to that black horizon where he was forgotten by his own family.

Finn threatens to tear the town apart to find Freya. Matt Donovan overhears and tells Finn and Elijah to leave. He’s just cleared the town of vampires.

Vince completes the spell and collapses. Lucian draws the potion from the bowl.

When Hayley and Klaus question the receptionist at the latest Kingmaker office, she rings an alarm and they’re attacked by armed guards. Hayley and Klaus take them out. In the basement they find werewolves hooked to venom extractors. There’s also a dead vampire.

Elijah threatens Matt, but Matt offers to help him find Freya.

Kol teaches Davina how to use the bowl to find the connection between Finn and Vincent. Finn falls, then says he knows where Vince is.

Vince tries to stop Lucian from drinking the potion, but the ancestors attack him. Lucian threatens to kill Freya, but Elijah shows up. Lucian downs the drink and asks if the brothers can get to him faster than he can kill their sister. Finn makes Matt shoot through Freya into Lucian’s chest. Freya and Lucian both fall. Elijah gives Freya his blood.

Hayley and Klaus let the wolves free and heal them with their blood. Klaus thinks Lucian was stealing werewolf venom to create a vaccine. They can’t figure out why he needed to test the cure on the dead vampire if he already knew it worked.

Matt tells Freya that Lucian is dead. She says they don’t understand. He wanted the Mikaelsons to kill him to take the final step in the spell. Lucian rises and fights them all. He bites Finn. He’s winning until Freya puts up a barrier spell. Lucian flees.

Kol loses control of his temper and punches a mirror. Davina tells him she thinks he’s cursed. He screams at her and runs. She magically tests his blood from the mirror.

Hayley tells Klaus to go home and heal Finn. She’ll take care of torching the lab. She says he should try to make Finn an ally.

Finn has hallucinations about betrayal and abandonment. The venom seems to be working twice as fast. Klaus gives Finn his blood.

One of the wolves tells Hayley they come from the seven packs, not just the Crescents. Lucian wanted their venom. He combined it until it was so powerful, there was no saving the vampire he tested it on.

Finn seems to heal. He thanks his family and says he feels a part of their “always and forever.” He even thanks Kol for Davina’s help. Suddenly, he’s throwing up again.

Klaus offers to continue healing Finn until Davina can remove the spell that locked him in his body. Then Freya will move his soul back to her pendant until they can figure out how to bring him back. Finn asks them to let him die. They stay by his side while he does.

The Mikaelson family scatters Finn’s ashes in the water and say a few words for his passing. Even Kol wishes him peace.

Davina meets Vince at St. James and asks for his help. She tells him that Kol’s blood was corrupted by the ancestors’ magic. Vince tells her that the ancestors are out of control and they need to take them down.

Hayley tells the Mikaelson clan that Lucian created a more lethal strain of werewolf venom. Freya says that’s what he added to the spell. They realize that he made enough for two. They run upstairs where Klaus imprisoned Aurora. She’s gone.
