Following the birth of his daughter, Klaus struggles to balance his parental responsibilities with leadership of the French Quarter. Elijah and Hayley try to determine where they stand in the aftermath of Celeste's reign of terror. Rebekah's own inner turmoil concerning Klaus' learning "The Secret" causes her to question her loyalties for a final time, while certain events also put the three twisted siblings on the slow path to reconciliation at long last. After burying Cami, Kieran decides he has had enough of vampires bossing him around and resolves to retake the city for the humans. Finally, a malevolent influence from a time before time threatens the very existence of the vampire and werewolf species.
