Klaus' POV
What's wrong with me, why am I behaving like this? Elena has always been with Stefan so why does it bother me now.
...
Elena snatches her necklace back from Stefan and tells him, "Thank you Stefan for telling me why I should consume vervain instead of wearing it."
Stefan keeps a hand on her shoulder and tells her, "Elena, it is not safe for you to be around Klaus and what I did was to save you so I don't mind you being angry on me for that. I will always protect you no matter what."
...
Klaus thinks Stefan is right, being with me is actually too careless for Elena and it's good that Stefan thinks for her safety.
Soon his relief shifts to rage when Stefan leans in to steal a kiss from her but what calms him is that Elena puts a hand between them, a few inches away from her face therefore stopping Stefan midway.
Stefan questions, "You're not gonna kiss me because I saved you. Fine, it just makes me love you even more." Stefan moves his arms across her back to pull her into a hug and Klaus is about yo throw a stake at him but stops when Elena steps back, "No Stefan, I am not in the mood, I just want to be alone that's it."
She leaves upstairs to her room and Stefan looks at her going. Klaus waits for Stefan to come out but instead Stefan walks to her kitchen and starts to cook for her.

Klaus' POV
Why am I wasting my time with the doppelganger, let her be with who she wants to be, why do I care? All I need is her blood to make more hybrids.
With this Klaus leaves.
...
He leaves to his manor and starts to paint, he is filled with thoughts, "did Elena let him kiss her after I was gone? Did she sleep with him post that meal which he prepared for her? Did she let him touch her the way he did before her union to him?
Flashback
When he was driving her back to Mystic Falls, after a long moment of silence she finally said, " You got cameras installed in my house, you are creepy, the first thing I'll do when I go home is find them and throw them in the dustbin."
Klaus pulls the brakes and tells her with a little loud voice, "No you won't because you won't remember it."
He puts two fingers on her chin and turns her to him, "Since you are playing vampire for a day I take it that you're not on vervain."
She purses her lips but when her heart skips a beat he realises he has got it right.
He smirks, "Ah, poor Elena, out to save her parents, full of vampire power and with a lack of vervain. How easily will I compel you."
Her heart beats faster and he enjoys it. "No" she says, she is about to closes her eyes but before she could do that Klaus starts with his compulsion, "Look at me Elena" and with that she turns to him eyes wide open.
"You will forget that there are cameras installed in your house. You will never deny me what I want, be it your blood or an invitation to your house."
He is about to start the car again but stops, he turns to her and pulls her in a kiss, a very deep and passionate kiss. He thinks she would slap him or resist but instead she kisses him back.
Soon his hands move to her body exploring her but she doesn't deny it, she let's him touch her. Soon Klaus breaks the kiss to look at her, thinking she would curse him or say anything but instead she comes closer to him claiming his lips again with hers. Her hand gently moving down his chest.
He vamps them both to the back seat and there they end up having sex in the car, in his car. When they are both done, she lies bare over his bare chest and he says, "I thought you would slap me when I kissed you, I didn't know you would take it till here? Honestly I kissed you to tease you."
Elena props her head up and says, "I wanted to but you said I can't deny you anything so I couldn't and I so hate you for this."
His eyes which were taking her beauty in suddenly got wide open and he sat up, making her sit too. He realised what mistake he made, when he compelled her it was purely for her blood supply not to make her sleep with him unwillingly.
"Dress up Elena" he says and she does, so does he. When she is all dressed up,
he gives her a kiss before telling her, "You have your free will Elena, next time I touch you and you don't want me to, then deny it, even slap me if you have to,
hit me, I give you your free will back. You will forget about the part where we slept together."
It's not that he didn't enjoy sleeping with her but it's that he wanted to do it when she wanted it too, this was unwilling and he was a monster in every way but not the one who sleeps with a girl without her consent. Had he known she didn't deny him because of the compulsion he wouldn't have taken it that far.
Had he known she didn't deny him because of the compulsion he would have stopped her then and there, but this just happened. It was non consensual but he didn't know because he had not chosen his words carefully. He is not at fault for what happened and the reason he took her memory away was unknown to him too.
Normally he doesn't care what other people think or suffer, but he had no idea why he took that memory away from her and why did he gave her back her free will, why didn't he enjoy making her dance to his tunes when he could. There would hardly be any chance when he finds her like this again. He drives silently back to her home thinking all that.
Elena was silent all the way after that because she knew she consumed vervain when Bonnie gave it to her, she didn't know how Klaus failed to notice it when he was in her sub conscious. Elena was silent because she slept with him willingly. She slept with him because it didn't feel wrong when he kissed her. She slept with him because his touch made her want more and when he questioned about the why she just blamed it on his compulsion because she didn't want to admit it to him that having sex with him felt so right.
She doesn't say a word to him after that and nor does he.
While driving from Elena's home to his he gets a call from the same witch "Klaus, you asked me to find any loopholes in the spell"
K, "well I am listening"
W, "Well there is one, I found it in one of the oldest grimoires I have."
K, "Well, care to tell me"
The witch reads to him "This unison can be sealed only by consummation, the consummation should be done on the day of the unison itself otherwise it will cease to create the pull."
K, "What do you mean by 'it will cease to create a pull'?"
W, "The ritual I performed bound her to you and the consummation you both did bounded you to her forever. Klaus you must stay away from her for a day because if either of you even tries to coax the other for it you won't be able to stop. The planetary forces won't let you, so I suggest you stay away from her for the time being."
K, "Well you're kind of late Drizzela because we already did that."
W, "Well, congratulations then, you are officially husband and wife." She disconnects before Klaus could yell at him.
Elena goes to her home and finds all the cameras first and destroys them.
Present
Klaus finishes the painting and it is of a ship sailing the sea through the storm just like his heart is.
He gives up and opens his laptop to check her house which he hasn't ever since their unison. What he finds is a week old footage of Elena destroying his cameras. After their return from DC he had ordered his hybrids that none but he and only he will check the footage of the Salvatore and Gilbert house but when he found this, he realised that she wasn't compelled.
He shuts the laptop down and grabs his car keys, ready to confront Elena over why she blamed it all on him when she was equally involved. Why did she blame it on the compulsion. And this time he would use compulsion to get the truth out of her.
