Martha sighed, letting the hot water relax her tired muscles. After a long time spent running and fearing for her life - again - she found that nothing quite beat the feel of a nice, hot bubble bath in the TARDIS for switching off the fight or flight frame of mind.
The bubbles parted as she lifted her leg out of the water. She watched the flow of the water as it ran off her leg and back into the tub. It seemed to glitter in the low lights. Content for the moment, she sighed and relaxed further under the bubbles.
