|“||You and Elijah have a choice.. from now on, it's either Klaus, or me.||”|
WAYWARD WAYS — Setting the stage for a bloody showdown, Dahlia gives Klaus and Hayley a deadline to turn over baby Hope. Elijah attempts to convince Klaus that they need to work together in their fight against Dahlia, but Klaus forges ahead with his own dangerous plan, leaving everyone concerned about his next steps. Meanwhile, when Hayley realizes their chances of outrunning Dahlia are slim, she devises a risky plan and enlists Aiden's help. Elsewhere, Freya gives Rebekah and Elijah an ultimatum, and Marcel strategizes on how best to deal with Klaus' erratic behavior. Cami and Davina also appear.
- Antagonist: Dahlia.
- Title meaning: the tensions in the Mikaelson family will finally come to a head.
- The phrase "When the levee breaks" refers to things being thrown out of balance. A levee is used in coastal regions, including southern Louisiana, in order to regulate water levels and protect the residents from the effects of hurricanes. When a levee breaks, the ocean water can flood the region it is meant to protect, as demonstrated by the effects of Hurricane Katrina on Louisiana and especially New Orleans in 2005.
- The Norse rune Freya carved into the stones for Mikael's memorial is called "gar", which is an adaptation of the Norse alphabet rune "gebu", and is analogous to the English letter "G". The rune can mean "gift" or "spear", and has been used to refer to Odin's spear Gungnir in Norse mythology. Gungnir was believed to have been given to Odin by Loki, and is known for always hitting its mark and always returning to the hand of its wielder.
- When this rune is used in divination, it can mean conflict, arguments, struggles, anger, confusion, hostility, and confrontations.
- Aiden is killed by Dahlia, who makes it appear that Klaus did it in order to turn the pack, Hayley, and the rest of Klaus' maternal half-siblings against him. Klaus takes the blame for Aiden's death to make Hayley doubt the pack's loyalty and to make the rest of the pack fear him, and tells only Camille the truth.
- Klaus is neutralized by the golden dagger when Elijah is convinced by Hayley that Klaus is too out of control to join everyone in protecting Hope.
- Goof - Hope can be seen crying right before Dahlia's plants grow, then again in the next shot, but the camera is angled to cover her mouth. All sound is cut out in both.
- It is confirmed by Rebekah that it has been a day since the events of Night Has A Thousand Eyes.
- Josephine - Beheaded; killed by Klaus (though she was originally killed and subsequently reanimated by Dahlia to send a message in Night Has A Thousand Eyes)
- Aiden - Heart extraction; killed by Dahlia
- Elijah, while talking to Klaus, mentions when Klaus broke his Hybrid Curse, after which Elijah almost killed him by ripping his heart out. This occurred in The Vampire Diaries Season Two episode The Sun Also Rises. This is the first mention of Elijah almost killing Klaus in either series since Elijah saved Klaus instead of ripping his heart out.
- Klaus mentions to Camille the first time he killed Mikael. This occurred in The Vampire Diaries Season Three episode Homecoming.
- Camille was last seen in Save My Soul.
- Freya holds a memorial for Mikael, which is visited by Rebekah and Elijah. Mikael was killed by Klaus in Night Has A Thousand Eyes.
- Davina mentions the golden dagger that can neutralize Klaus, which she made with Kol in I Love You, Goodbye. Davina also mentions Kol's death, which occurred in the same episode due to the death hex Finn cast on him in Sanctuary.
- Dahlia is the second witch in the series to use magic to extract a heart. The first was her nephew, Finn Mikaelson, who used it to kill a vampire in Sanctuary.
- Elijah being tortured by Esther was mentioned in this episode. This occurred from Red Door to Wheel Inside the Wheel.
- Finn was mentioned in this episode. His spirit was removed from Vincent's body and absorbed into Freya's Talisman by Freya herself in They All Asked For You.
- Esther was mentioned in this episode by Klaus and Dahlia. She was killed by Freya in Exquisite Corpse.
- Eva Sinclair was mentioned in this episode. Her spirit was destroyed by Rebekah in Exquisite Corpse.
- Klaus mentions to Elijah the following events in which Freya helped Finn.

- Klaus (to Elijah): "Is something the matter, brother? Can I fix you a drink, perhaps?"
- Elijah: Strangely enough Niklaus, I'm not in a mimosa mood.
- Klaus: "Fantastic. More for me."
- Elijah: "Let's discuss strategy, shall we, Niklaus? Just wondering if you have one. We can begins with Mikael's ashes. Given that they are the main ingredient in our weapon against Dahlia, would you care to tell me where they disappeared to?"
- Klaus: "Elijah, I have compelled the city's finest pastry chef for your own personal edification, and yet you ignore my efforts in favour of needless concerns."
- Rebekah (to Klaus and Elijah): "Can we stop talking so loudly? Give me that."

- Klaus: "Whoever said opportunity only knocks once, eh?"
- Camille (to Klaus): "Bad time?"
- Klaus: "Camille. Ah, yes. As I've recently proved disagreeable, I assume Elijah asked you here to play therapist to the savage beast."
- Camille: "Actually, I was just gonna say you look like you could use some fresh air. Maybe we could go for a walk. You could spend, I don't know, five seconds not obsessing about who not to trust and who're gonna murder next."

- Klaus: "Which is a far cry from being trustworthy!"
- Freya (to Rebekah): "From now on, it's either Klaus or me."
