The Doctor had tears in his eyes, He knew he had to see her even if it was the last thing he did, "Rose... its me, The Doctor, I just need to see you," He was not sure how she would react. But he felt so heartbroken and lost that he needed to see her, his eyes were dull. He seemed so sick and miserable. "I miss you," he had tears falling down his face now.

He wondered if she would open the door. He coughed and gasped again. His cough and headache was driving him crazy. If anything happened he just wanted to have seen her. He couldn't even sleep anymore without thinking about her.
"I can't stop thinking about you and I am so so sorry." He said apologizing over and over like he sometimes did.
