It was a dark night in New Orleans, as Klaus entered the compound alone to face Marcel, only to find Rebecca alongside him.
A moment later, a bunch of vampires appeared, making a huge circle around where Klaus stood.
"What's this?" Klaus questioned him.
Marcel informed him of his intentions.
"You think you can subdue me with this!" Klaus yelled at Marcel, before addressing the vamps. "Vampires of New Orleans, as you know, I am an Original hybrid. I cannot be killed! Now-"he took out a coin. "anyone that picks up this coin gets to live." He tossed it, but none of them made a move to pick it up. "Well then, come on!"
Suddenly, chains were thrown onto his wrists.
He looked at the vampires and then at Marcel and Rebecca, as his vampire side tried to get free, pulling on the chains that the vampires held tightly onto. Since his vampire side couldn't break free, he stood there for a few minutes until his eyes turned yellow like a werewolf's.
"Pick up the coin," Rebecca told Marcel.
"What?"
"He's going to kill us all," she explained, just as Klaus broke free of the chains and started killing vampires left and right by ripping out vampire hearts at hybrid speed.
"No. We end this tonight," he said to her. "He's going down."
Marcel watched, as Klaus slaughtered every last one of his vampire companions he had known at different number of years. Then, Klaus grabbed Marcel and pinned him against a wall with a growl, hatred of him showing. He was too far gone at this point to even care about what he was going to do.
Not wanting to die, Rebecca picked up the coin.
"Nik, stop!" she said to him, knowing that he would stop at nothing, when he was determined. She knew that that was just how he was these days.
Hearing her, he looked at his only sister whom had betrayed him time and time again, each in different times, whom now held the coin up in her hand.
He looked at Marcel with a growl.
"For your disloyalty, sister; forgive me," he said, before ripping out Marcel's heart and letting both pieces of him fall to the ground, before looking at her, before leaving her alone in the compound to think about what she had done. He wouldn't kill his sister this time around, much less dagger her, but he could punish her in other ways. One way was killing Marcel whom he had thought of as a son 100 years ago.
As he headed for the plantation home to go get Elijah and Katerina to take them to the compound where they would all be living at, he slowly calmed himself, turning his eyes from yellow to their normal color.
The next day, Katerina was sitting on the porch, having heard about what had all happened at the compound, when Klaus walked out of the house with Elijah and headed for his SUV.
"Come on, Katerina. We're going to our real home now."
Without any hesitation, she went with them both, knowing what he meant by their real home. He meant that they were going to live at the compound where the Originals had lived in the first place when they had first come to New Orleans.
