Determined to make her ultimate move against the Mikaelson brothers, Aurora (guest star Rebecca Breeds) uses Freya (Riley Voelkel) as bait to lure Klaus (Joseph Morgan) and Elijah (Daniel Gillies) into a dangerous trap. Meanwhile, after being recruited by The Strix's powerful coven of witches to perform a spell that could save the lives of her closest friends, Davina (Danielle Campbell) finds a way to conjure up Kol (guest star Nathaniel Buzolic), the only person who may know the key ingredient to completing the spell.

A new promo for the episode opens with Klaus and Elijah in a forest as Aurora has taken Freya as a leverage to draw the Mikaelson brothers out. Elijah tells his brother: "Whatever happens, you promise me..." but Klaus cuts him short and says: "Aurora dies today." With two Original vampires hunting her, looks like Aurora's days are numbered.

Aurora will play a cat and game mouse with the Mikaelson brothers to give away the bullets she made from the White Oak tree. Fans know that the White Oak tree is the only weapon on Earth that can permanently kill an Original vampire.

The promo ends with Aurora shooting at Klaus. Meanwhile, Davina will do everything in her power to resurrect Kol in the episode.
