Klaus laughs when he finally catches on to the truth that everyone seems to be aware of except him. His hybrid army isn't working as he had hoped because, contrary to what he had thought, he ihadn't/i fully broken the curse. The doppelganger is still alive.
He sends Stefan off to Washington to give himself enough time to do what has to be done without any heroics on his comrade's part interfering in his plans and then he heads to Mystic Falls.
He sneaks into her house in the middle of the night, compels her brother to leave the house, and waits.
He makes her breakfast in the morning, anticipating her arrival in the kitchen—even pours them both a cup of coffee.
"Alaric," he hears her say as she's coming down the stairs. "How many times have I told you, you are not required to make—" she freezes when she sees him.
"Looks like I didn't kill the doppelganger after all."
Her breathing is controlled, her eyes fixed on him. Her effort to maintain control and stay calm is very admirable, he thinks to himself as he sits down at the kitchen table. He motions for her to follow.
"I made breakfast," he states needlessly. "The least you could do is sit down and enjoy it with me."
He can practically ihear/i the reply she wants to say but holds back as she slowly makes her way to the table. Her hesitance is warranted, he will admit, so he doesn't hold it against her.
"What do you want?" she asks.
Klaus tilts his head. It has been a long while since someone has asked him that question. "I'm not sure at the moment," he answers. "I thought I knew…but things weren't progressing as I had hoped, and then I receive the news that the very lovely human doppelganger is still alive and I have to wonder—is it wrong to deviate from my desires if I find something that I want more?"
She stares at him blankly.
"You haven't touched your food," he says. "It's actually quite good."
Her head tilts just slightly, but she takes a forkful of scrambled eggs and puts it in her mouth. He watches in amusement as she eats in silence, trying to conceal the fact that she is actually enjoying the meal.
"Here's the problem, my lovely doppelganger; I cannot create a hybrid army with you still alive, but I have found that I am…hesitant to kill you." He shrugs and takes a drink from the coffee cup in his hand, trying to make light of the serious problem on his hands.
"I don't want to die," Elena tells him honestly, an expression of acceptance on her face.
She thinks he's playing with her, yet she is being honest. He surveys the domestic scene in front of him carefully, an idea forming in his mind. "You could come with me," he offers. "We could start our own family…a family of hybrids."
