The Helmet
The Doctor was already wearing a white pilot outfit when she found him on the runway. He seemed to be expecting her, standing there with the helmet under his arm. The plane was behind him, scary black thing they fight wars with.
"I wish you wouldn't have to do this" she said to him, looking to his brown eyes. He looked old again, 900 years of wars and fights and flying scary aircrafts. But it was different this time. This time he might die and he had promised her a lifetime together. "I won't go if you tell me not to" he said. He had never said that before, but of course they both knew that he had to go. He could help so he could not not to. He wouldn't be the man she loved if he wouldn't go, and he would love her little less if she would prevent him going. Her eyes filled up with tears but she pulled herself together and nodded to him. Go. He smiled to her, to his brave Rose who did things she wouldn't dare to because she had to. His smile made her brave, so she smiled back to him, her brilliant smile. He was called, he had to go, they had to hurry. She put her hands to his shoulders and reached up to his face and kissed him. He pulled her closer with his free arm and kissed her back greedily. It was desperate, passionate kiss and he wished it would never end but of course it did. She pulled back and helped him to put his helmet on. "Helmet too" he said behind the visor and showed where he wanted her to kiss it. She smiled and kissed the helmet, and then watched him to go.
Later, when he took the helmet off, in that small yellow life boat where the pilot and he had climbed from icy ocean, he looked at the visor and exclaimed happily: "Look Roger, there's still her lip gloss on it". Roger was not amused.
