2024 and im coming here to say after therapy..that Klaroline never would be the end game, their bond was shared through so much trauma and suffering, Klaus hurting her, then running for her rescue. Love doesnt mean wounding someone so they would need you. That is why pure love based on trust first always wins, it will hit you when you least expect it. I knew someone who would like me the way Klaus does, and I understand why she wouldnt chose him, he has primarily obsession with having her, rather then wanting to have healthy relationship. Nonethless to say..if Klaus just met Caroline and she would like him back, he would be probably the most obsessed cute vampire husband.
Caroline never loved Klaus and that's why I feel pity for him he changed his attitude so much for her and she didn't give a damn about him and she regretted it when he died to save his daughter.
