"I will never leave her alone."
...
Later that night Klaus loomed outside of the Gilbert house. He had kept his watchful eye on Elena for the past week or so.
The whole fiasco with his family just ended. Klaus was able to sneak away from their over-bearing mother. The rest were all teaching mother about the changed society.
Since she had been dead for a thousand years.
Klaus froze out of his thoughts when he heard the inaudible sound of an opening window. "Come in here please. You look really creepy and lovesick stand outside my window."
Klaus was surprised by her attitude. But in a flash, Klaus was up in her room. She stood there rigid. "What do you want now?" she demanded emotionlessly.
"To check on you," he shrugged, he looked around the room vacantly. "Why?" she asked stupidly. "I care about the well-being of my doppelganger you know," he looked directly at her.
She flinched. "I'm fine, but I heard your mother is back. Along with the rest of your family," Elena said. "Damon talked to you. I'm assuming," he replied nonchalantly.
"I just want to make sure that we have an understanding," he said suddenly. Coming closer to her. She froze. She arched a questioning brow. "I will never leave you alone," he stated seriously. Her eyes lighted with surprise as she kept her deep gaze on him.
"I'll make sure you're safe from everything. Including the Salvatores," he said, grounding the last part out through his teeth.
She gulped. "Thank you," she replied stupid and breathless. She was too overwhelmed, she knew this was a subtle way of Klaus staking his claim over her.
Surprisingly and sickeningly. She didn't mind.
