"I am so sorry, Rose," The Doctor really felt guilty for all of that. He hadn't ever wanted to hurt her. He knew that doing what he had, really upset her. He could see it now. He knew sometimes he was just foolish.
"I was foolish," He knew that things were sometimes just hard. He knew that it would get harder when she was older. "I will say good bye properly next time," He wished there didn't have to be a next time. 
The Doctor kissed her and looked at her, tears fell from his eyes. He wished she could be with him forever.

Jack was walking by Caitlyn. He knew how the Doctor must be feeling. He was looking at her "yeah," He replied.
