FIVE YEARS LATER — On the fifth anniversary of Klaus' defeat, Marcel is king of the city and welcomes the un-sired vampires to New Orleans, only to find they pose an unexpected threat to his rule, leading him to seek counsel from an unlikely source. Meanwhile, as Hayley closes in on the cure that will allow her to revive Elijah and the slumbering Mikaelsons, she faces a final task that will force her to make a ruthless decision. Vincent and Freya also appear.
- There's a five year time jump, placing the events of this episode in May 2019, 14 months after the events of TVD's series finale.
- In those five years, there was peace with even a truce between Vampires and Witches.
- There is no truce with the werewolves.
- With Arcadius dead, Marcel Gerard is currently the most powerful being in the TVD and TO universe known to date.
- This is the first season premiere not to feature Kol and Rebekah Mikaelson.
- Hayley tells Mary that she had found a witch to siphon the magic of Rebekah's hex and found a cure for Freya's poison.
- Valerie Tulle may be the witch Hayley is talking about as she's the only remaining siphoner besides Josie and Lizzie Saltzman.
- Klaus is now kept chained up in the Mikaelson compound by Marcel.
- Marcel, Josh and Vincent mention Camille.
- Alistair was yet another vampire who was compelled to slaughter his family as well as his entire estate and was used to distract Mikael so that Klaus could escape.
- The beast anti-venom is finally created by Freya, her magic amplified by five dark objects, using Klaus' blood mixed with the venom of seven werewolf packs. It successfully cures Elijah and Kol though there was only enough for two doses.
- Freya's amplified pain infliction spell shows that one only needs to completely destroy a vampire's brain to kill them rather than a complete decapitation. Keelin described this phenomena as "melting".

Behind the Scenes
- This is the first season of The Originals to premiere without its parent show The Vampire Diaries being on air at the same time. "Gather Up The Killers" aired one week after the TVD series finale.
- Vincent: "This week marks five years since the fall of the Mikaelsons. We've managed to keep our monsters buried and now we've got to make sure that they stay buried."
- Hayley: "After all this time, I am this close to getting them back."
- Marcel: "I put him down. I kept him down."
- Sofya: "Hayley is trying to bring the Mikaelsons back."
- Vincent: "This city, everyone in it, is in danger."
- Man: "Give up now and we'll end this quick."
- Klaus: "Camille, Camille!"
- Camille: "I'm here."
- Hayley: "I'm trying to save my family."
- Sofya: "Every vampire either loves you or fears you."
- Klaus: "Have you come to taunt me, Marcellus?"
- Marcel: "New Orleans is the city that you like to say you built. It's mine."
- Vincent: "It's a beautiful day outside. Streets are packed with tourists, they're drinking beers, they're chasing beads, headed out on the vampire walking tour of New Orleans. They think it's a myth: just part of our city's charm. Well, we know better. Just like we know that there's a storm coming. This week marks five years since the fall of the Mikaelsons. Five years of peace and we paid a high price for that peace. We witches, we earned that peace. We snatched back our freedom, we severed our link with our ancestors. To take back our city, we back Marcel Gerard. Now since then, we fought hard to build this community and in the next week, as we celebrate our independence, that community will be challenged."
