When Damon was back to Mystic Falls he saw Bonnie. She couldn't recall a thing, so Damon told her everything that happened in Mystic Falls. She was so upset, that she started crying. Damon hugged her, putting his hands on her waist. She hugged him tighter and started crying even more. When she calmed down and leaved his embrace, she turned red, looked shyly in his eyes and slowly blinked. Bonnie got closer to his lips and kissed him. Damon was shocked, but gladly kissed her back.
At that passionate moment Caroline entered the room, still holding Klaus's hand. She was going to tell Bonnie about Klaus and her getting together. When Caroline saw their kiss she couldn't believe her eyes. Damon caught sight of Caroline and Klaus and left Bonnie's sweet lips. Bonnie noticed Caroline and Klaus as well and didn't know what to say. But when she noticed them holding hands, she was so happy that she ran and hugged Caroline tightly. She looked shyly at Caroline, searching for her reaction on The kiss. Caroline smiled and a tear ran down her face. She hugged Bonnie as well and told her, that she was very happy for them. Damon after The kiss understood, that he loved Bonnie. Their common hate turned into love of whole life.
