Yaz, Ryan and Graham witness what appears to be the Doctor's death at the hands of the Master. Four years later, Yaz starts having dreams that the Doctor needs her. In Philadelphia, Calista, an alien the Doctor saved in his Eleventh form, has grown up to work as a psychologist. An abused amnesiac Jane Doe recognizes her. The Master is still at large and Calista and Yaz will have to find each other to keep the Doctor safe.

Amnesiac in America

I will never forget when the Doctor died.

The Master was destroying planets across the universe. The Doctor, Graham, Ryan, and I finally caught up with him on an already burning planet.

"Stop this!" the Doctor pleaded. "Stop the killing!"

"I'll only stop one condition," he said. "You be my last kill."

"I don't believe you," she said. "You'll keep killing afterwards."

The Master pulled out his tissue compressor. There were six people. He walked over to the nearest flames.

"NO!" she screamed.

"On your knees," he said.

"Doctor no!" I cried.

"Just don't kill them or my friends," she said as she kneeled down.

"Fine," he said. "They can be witnesses."

"Give Yaz the people," the Doctor said.

He sighed and tossed me the screaming pocket-sized people.

"Doc!" Graham cried.

"Please," Ryan said.

The Master laughed.

"It's going to be okay," the Doctor, said looking at us. "I love you all."

There were tears in her eyes.

The Master pulled out a white space gun and shot her in the head. Her body dissolved until there was nothing left but her clothes.

Graham held me as I screamed.

"Get out!" the Master said. "Get out and tell the universe there is a new sheriff and his name is the Master!"

Graham and Ryan dragged me into the TARDIS. We managed to find a planet drop off the compressed beings and revert them to their original size. The TARDIS then dropped us off at home. The minute we stepped out, it disappeared.

That was four years ago. Stars keep going out and scientists can't figure out why. Alien abduction stories fill the fringe news sites. The world is a darker place since the Doctor died.

Three weeks ago, I started having odd dreams. The Doctor would appear with single message.

"Come find me."

…

My name Calisobala Ak Melbodonia. I come from the planet Newmania. It was invaded by the Daleks. My parents were killed when I was six, in front of me by them. I was next when a man in a bowtie distracted them and ordered me to hide. He found me later, crying in the attic. Calling himself the Doctor, he looked around for someone take me in. My village, my planet had been decimated. I was the last of my kind. He took me in his spaceship that resembled a blue box that was bigger on the inside. We traveled to different planets looking for a new home for me. On Earth he found a woman named Elvira, in America who took in alien refugees. I took on the name Calista Melbon

A year later Elvira was killed by alien hunters, who were never apprehended. I was put in foster care in Philadelphia. They put me in special classes, because I didn't know my ABCs or speak English particularly well. I learned from Elvira to hide my alien heritage as I resembled a human in biology. Still, I was bullied mercilessly. I managed to get in to Penn State and then life got easier.

Today I am a staff psychologist at Lambert-Adams Behavior Health Hospital in Philadelphia. I enjoy my work. No one knows my secret. I prefer to keep it that way.

It was the start of another day. My supervisor met with those of us who worked with trauma-induced psychosis. She passed me a file.

"Meet Jane Doe of Wilson Avenue," she said. "She is mute and doesn't respond well to directions."

I skimmed the file. In her late thirties, with blond hair and blue eyes, in the she looked malnourished. There were signs of abuse.

"Did anyone look for a missing person's report on her?"

"The police did, after they found her sleeping in a snow bank wearing nothing but a white dress with odd black markings on it. Detective Mark Webb wants you to keep him informed on your progress."

"Duly noted," I said.

I took the report into my office and added it to my pile. Nothing about the case struck me as particularly odd at the time.

…

I met her in an observation room with soft surfaces and gentle lighting. She was curled up in a corner shaking. Gently closing the door, and getting on her level, I cautiously approached her, as she was known to lash out if suddenly disturbed.

"Hi," I said softly.

Her glassy eyes suddenly changed. She stopped shaking. A smile appeared.

"Calisobala!" she said excitedly. "What a fine young woman you've grown into!"

She didn't say any of that in English. To the average human, my native language sounded like gibberish.

"Do you speak English?" I asked.

"Are you a Doctor?" she asked in Newmanian. "Your parents would be so proud!"

This was the quandary of my life. Help the patient and expose my identity or pretend to be the befuddled doctor I should be.

I nodded. This was going to be tricky.

"Are you from Newmania?" I asked in Newmanian but purposely making mistakes.

"You've forgotten your home language," she said. "I don't know where I'm from."

"What is the last thing you remember?" I asked in broken Newmanian.

She turned away.

"Bad things. I was hurt constantly. They didn't give me enough to eat. Most of my body was blue with bruises. They liked my hair. My hair was kept clean and trimmed nicely. The rest of my body was broken.

"Who is they?" I asked in Newmanian.

"The Cusickians," she said. "My body was sold to them."

"What is your name?" I asked.

She slammed her fist on the ground.

"I don't know. I don't know! The called me Prisoner Delta. That was all I was until I broke free and found a transmat and beamed myself to the last place I felt safe. I don't know who I am!"

She burst into tears.

"Enough for today," I said gently.

"Calisobala, help me!" she cried. "Help me remember. Help me find my home!"

"I promise, I'll help you," I said and stood up. "I'll see you tomorrow."

I left the room. The care assistants stared at me in shock.

"Hello," I said in Newmanian and then reverted to English. "I repeated the gibberish in soothing tones. She thinks we had a great conversation."

I left before they could ask any more questions.

Once I was safely in my office, I sighed. I didn't doubt the fact she was an alien. From what planet, I wasn't sure. It was too much to hope that she was of my kind.

The Cusickians had abducted my maternal aunt before I was born. She was quiet and easily spooked, my mom told me bad things had happened to her while in their custody before she escaped.

Odd things had been happening for a while now. Something wasn't right in the universe. I felt it in my alien bones. This woman might be the key to unlocking everything.
