All of Martha's focus over the past few days had been work. Being a doctor, fixing people, helping with the injuries. She moved through her motions without any hint of emotion, keeping everything bottled up until she was alone. It was when she was alone that she cried, curled up into the pillow on her bed, missing Rose, missing Tony. Sometimes she clung onto the shirt Tony had left the last time he had been in her room, as if holding on that tightly could bring him back.
And when the tears ran out, she would sleep for a while, wake up and continue on, back to work, back to being a doctor, Doctor Jones, UNIT soldier, the woman who walked the Earth alone. All business, no emotion. The only sign that anything was wrong being the redness in her eyes and the worn expression on her face, her dark skin lacking the usual glow of enthusiasm she normally had.
But that didn't mean she missed what others around her were feeling. She could see Jack's worry over Becker, the soldier's frustration over being forced to rest, and the Doctor, oh always the Doctor. This one had never met her before, but accepted her anyway, let her stay on the TARDIS, and she worried about him. So much.
She saw where he was before she went to the kitchen, making up some food. Really, she wasn't even sure what it was, a sandwich of some kind. And a banana. Because bananas were good. And quietly she wandered over to him, gently sitting down beside him and holding out the plate as she dangled her own feet over the edge of the ramp. "You need to eat something."
