Martha Jones was tired. Tired of all the death and destruction, tired of fighting, tired of being alone. It wasn't supposed to be like this. She wanted things to go back to the way they were before she'd even heard of The Master. When it was just here and The Doctor, traveling in the TARDIS. Martha sighed, then readjusted her pack and trudged on despite the biting cold and driving rain. The Doctor had given her a mission, and she was going to do it. It was the only way to save what was left of the world.
