It was a dark night, as Katherine reached the compound, limping, vision going gray, heavily bleeding from her wounds. And once on the Mikaelson doorstep, she felt something hard beneath her, vision going black.
Klaus was on his way out, when he smelled blood; human blood. And once he opened the door, he was shocked to see a very human Katerina on her back on the porch.
He knelt down beside her.
"Katerina?" he called, as he assessed her condition and wounds with his eyes.
"Klaus…" she murmured, barely awake.
He pulled her gently into his arms.
"I'm here, luv," he assured her.
He got to his feet with her in his arms and hybrid-sped inside and to his room.
By the time he had gently layed her down on her back on his bed, she had blacked out.
He sat on her bedside and bit his wrist, putting it to her lips, making his blood go down her throat to heal her after what looked to be a vampire attack, hoping it would work, knowing that she had gotten the cure shoved down her throat.
A few minutes later, he took his wrist away and her wounds and his wrist healed.
He sighed in relief, glad that she would live to see another day. He had never shown it, but he had always secretly loved her and cared about her.
He rested a gentle hand on the left side of her face, looking down at her, and waited for her to awaken.
When she woke up, it was still dark outside and she was in Klaus' room, who was seated on her bedside, looking at her like he cared for her.
"Tell me who did that to you," he said, before she could say anything.
"It was a vampire. That's all I know. Why didn't you kill me when you had the chance? I'm not worth anything to you anymore. I'm useless to you; especially, now that I'm a weak, helpless human."
"Is it so hard to believe that I care about what happens to you?" he questioned her.
"Yes."
"Why? Apart from what I did 500 years ago, why?"
"Because like me, you'll always be the monster," she replied.
"Is that really what you think of me? A monster? I saved your life tonight. I even refrained from showing up back in town to see you. I kept my distance, despite your change."
"If you want to help me, then do it. All I've had this summer is fear, loneliness, and hatred."
"Then I'll help you. Despite what you think, we are alike, you and I."
She gave a smile.
"That we are."
He smiled back.
A moment later, they were kissing with him on top.
