When Klaus starts getting mysterious clues related to Hayley’s kidnapping, Klaus decides to put additional pressure on Marcel, Vincent, and the three factions. We review The Originals, “Between the Devil and the Deep Blue Sea”.

The lesson for The Originals Season 5? Apparently, it’s “I don’t do well without Elijah…”
In “Between the Devil and the Deep Blue Sea”, NOLA is preparing for Mardi Gras. As Vincent says so beautifully: “Where another city would buckle, New Orleans turns misery into magic.” Truest of TRUFAX!
However, while the rest of NOLA prepares for celebration, Klaus returns from France alone and even more determined to find Hayley, by any means necessary. Soon, we learn these means involve playing the Witches, Crescent Wolves, and Vampires off one another. Klaus gives all three factions an ultimatum–that if they fail to find (or return) Hayley, the Mikaelsons will rain death and destruction down on all their houses. Marcel, who speculates that something is off with Klaus, joins in for the search for Hayley, a search which gets more alarming once the clues that rolling in. First, they get a mysterious note with an address in Treme, and when Klaus and Marcel get to the house, it’s empty, but only recently so. Whoever was there left behind a chair and ropes with wolfsbane and vervain. There’s also a message written on the wall in blood: FREAK FILTH CROSSBREED. Yep, someone was keeping Hayley at that house! This has Klaus all shook and drives him even further to the brink. He ends up kidnapping one witch (Colette), vampire (Josh), and wolf (David)? If Hayley isn’t returned by the end of the day, Klaus promises to kill the three.
It needs to be said that Klaus is making some *major* assumptions. He’s thinking that because Hayley is a hybrid, some enterprising person among the Witches, Crescent Wolves, and Vampires would see her as a threat and want to eliminate her, especially if it would strike fear into the Mikaelsons. But…… what if an outsider is the one that has Hayley? Also, we haven’t seen Irish Declan in some time… Yes, I’m still suspicious of that guy. Fine AF, but suspect.
“I don’t do well without Elijah…” Klaus says that same thing to Caroline and now to Marcel… Klaus goes as far as to confess that Elijah knows he’s a Mikaelson and wouldn’t return to NOLA to help search for Hayley. As they’re talking, another clue arrives, this time a piece of Hayley’s body bearing her crescent birthmark, Klaus loses it. He kills Colette and David, but is interrupted by Vincent before he can kill Josh.
At this point, Vincent also recognizes that, without Elijah, there are no restraints on Klaus’s menace. Upon increasing pressure, especially from Josh and Vincent, Marcel decides to lock Klaus away. But Klaus has a final message for his adoptive son: “A vampire took Hayley so that those who care for her would suffer.” And if Marcel doesn’t watch his back, they might be coming for him next.
Meanwhile, in Mystic Falls, Hope is working on her own and trying to use her magic, plus research magic around the world to find her mom. It’s a good thing that Auntie Freya decides to make a surprise visit for some girl time and beignets. This includes a tour of campus… can we talk about the feels of being back in the Salvatore house?! *SIGH* Also, I see what they’re trying to do, making Roman seem likeable by showing him playing shirts/skins soccer with his buddies and being sympathetic to Hope. Well, I’m not falling for it and I really don’t want Freya to be encouraging Hope to befriend Roman. In any event, Freya has also come to Mystic Falls for another reason, to tell Hope about the reading Vincent and Ivy did, predicting that Hope would either be the source of untold peace and prosperity for NOLA OR the source all their deaths and downfall.
It’s interesting the Vincent told Freya about the reading… interesting that Freya is telling Hope, too. But given that Freya was raised by her own aunt who spent centuries manipulating her, I can see how Freya would want better for her relationship with Hope. Besides, of all people, Freya is the one who could teach Hope to control her tendencies toward darkness.

In the end, Marcel frees Klaus. Side by side, they will search for Hayley and look out for NOLA’s best interests. This also means that, until they can the trusted and Hayley is found, all Vampires must give up their daylight rings. I doubt this endears Marcel to the Vampires, especially as Greta (and maybe even Josh) is fomenting discord. WOWSA.
As for Vincent, he’s 100% done with Klaus and tells him so. When Klaus comes to him during Colette’s burial ceremony, Vincent refuses any help and promises to take down Klaus himself should he attack the Witches again.

Lisena rallies the Crescent Wolves after David’s funeral ceremony, saying that they need to be prepared to fight.
Klaus and Marcel get one last message–when Klaus throws the box that carried Hayley’s birthmark (out of frustration), it breaks and a coin tumbles out, a coin with a swastika. Let me tell you, when I first saw that I raged, because I really don’t understand why every show is making Nazis their big-bad. Seriously, it’s a BAD IDEA. But, alas, in the past, the Mikaelsons had some dealings with vampires somehow connected to the Nazis. According to TVGuide.com, in the upcoming episode:
“…we’ll flash back to Germany in the 1930s, when Klaus was up against a cult that hunted werewolves and slaughtered them by the pack. It’s looking more and more like this cult (or a modern day version of it) could be behind Hayley’s disappearance and the bigoted hybrid language that was scrawled across the former site of her captivity.”
We shall see…

The Originals airs Wednesdays at 9:00pm ET|PT on The CW.
