Clara's hand was shaking as she dialled the number, triple-checking before she hit the green call button.
The phone rung a few times, before a woman's voice picked up. "Hello?"
"Hi, is this Martha Jones?" Clara asked nervously.
"Yes..." the woman sounded rather suspicious.
"My name is Clara Oswald. I used to travel with the Doctor," Clara explained.
There was a pause. Clara assumed that Martha was taking the time to absorb the information. "Then we have something in common," Martha said finally. "How's he doing? Hang on, you said you used to travel with him. Are you all right?"
"He's fine," Clara said. She hesitated, before adding, "He's gone home to Gallifrey."
Despite this revelation, Martha didn't miss the omission in Clara's response. "You haven't answered my second question."
Clara sighed. "I need you to help me with something."
"Okay, what is it?" Martha silently wondered what had happened to the Doctor's latest companion. It must have been related to the recent Cyberman invasion. UNIT had recruited Mickey and herself to aid recovery, but she wasn't familiar with the details of the Doctor's involvement.
"I have a device that needs recharging. Like a vortex manipulator, but much more complicated. With the Doctor gone, I figured you would be my best chance of getting it fixed." Clara waited nervously for Martha's response.
"I'll do my best," Martha promised. "Do you want to come over and discuss? I'm based in South London now."
Clara suppress the urge to sigh in relief. There was hope for her after all.
"That would be great."
