Wet and cold -After running off upset in the rain when he has an argument with Rose, Rose finds him soaked and in tears. Shortly after the Doctor comes down with a nasty cold. Which leaves Rose worried about him.
The Doctor looked at Rose seeming upset. They had been arguing, he wasn't used to arguing with her much.
But she had been worried about him lately and he had snapped and told her that he didn't need worrying about, she had been concerned about fact he overdid it sometimes.
Looking at her once more he ran outside in the rain. Slamming the door to her house.
