Hi, I don't write here often, but I feel like something new, so here I am.
Command Override
The second snap was a signal. For what, they didn't know until they got back in the TARDIS and the doors were firmly closed.
It started out the way many of their trips had started: on the way to one place and ending up in a completely different location. The destination was a place people lived treehouses and used special wings to fly from tree to tree. But then a distress signal came in and they headed to an asteroid belt.
Landing on the largest rock, the Doctor used the sonic screwdriver to guide them to the source of distress. It was a single white light on black pole. After the Doctor scanned it and turned around. There was a look of fear in her eyes like none of them had ever seen.
"RUN!" she shouted.
By now they knew better than to question her orders. Their lives were in peril and they needed to get out as quickly as possible.
No had seen her open the doors with a snap of her fingers before. She snapped them twice just as they were within a few feet of the TARDIS. For once the Doctor wasn't leading. She kept looking over her shoulder and pushed them forward. Once Graham was over the threshold, the Doctor let out a blood-curdling scream as she was pulled away from them and into the darkness.
The doors wouldn't open again. The TARDIS began to move as if in traveling mode. A projection of the Doctor appeared.
"If you're seeing this, it means our time traveling together has come to an end," she said calmly. "I am facing a danger that only I can face alone. I have programmed the TARDIS to send you home two minutes after we last departed. Graham, Grace would be proud of your choice to live life beyond what you could see and enjoy time with your grandson. Ryan, I am so proud of you. There isn't a challenge on any plane of existence you can't conquer. Yaz, you have so much to offer to the universe. Take care of the boys for me, okay?"
The transmission ended.
"No!" Yaz shouted. "There's got to be something we can do! Anything!"
Another voice filled the TARDIS.
"You, silly man," the female voice said. "If you've set this up because you doubt your friends, then I'm here to set the record straight. I'm taking over."
Graham looked around.
"Who do you suppose that is?"
The TARDIS lurched around. Yaz held on.
"I'm not sure I care so long as she can help us save the doctor," she said.
…
She woke up cold. Pressed against a cold metal surface, she was wearing no clothes. Taking a calming breath, she tested the restraints and felt no give. The Doctor knew that was not worst thing that was going to happen to her.
"Hello Doctor," a cold menacing voice said.
A humanoid greenish cat figure appeared.
The Doctor let out a sigh.
"I had sincerely hoped your race had gone extinct. That you were only a bogeyman, time lords were warned about before they acquired a TARDIS."
It laughed and pulled out an enormous syringe.
"Isn't there a famous a writer from Earth who once said: 'Reports of my death are greatly exaggerated.'"
It plunged the needle in her neck and the Doctor screamed.
