Nightmares
"Maddy!" The Doctor shouted. He waited a few moments, and then shouted for her again. Three minutes later, the blonde with anger issues still wasn't there. The Doctors face pulled a thinking look and then he stopped piloting the TARDIS. That's odd. He thought. She's always here within two minutes of being called, no matter where she is on the TARDIS. He slowly walked out of the main control room to look for the girl.
After an hour or two of searching, he finally found her in the library. She had at one point been perched on one of the armchairs, but now she was on the floor, curled around a book called Elementals. The Doctor gave her a soft smile and crouched down next to the sleeping girl. He reached out and placed a hand on her shoulder. The next thing he knew, he was laying flat on his back and Maddy was stretched out, no longer curled up innocently.
"She tries to kill people in her sleep… Fantastic." He muttered to himself sarcastically. The Doctor reached out again, this time avoiding physical contact, just letting his hand hover over the sleeping figure. When she rolled herself into a ball again, she started moaning and whimpering in her sleep.
"Shh, Maddy. It's just me. Just the Doctor. Not gonna hurt you, I promise." He said, his face stretching into a grin. He slowly started to stroke her hair, murmuring nothings to calm his companion.
"Shh, Maddy. It's alright, I'm here now." He whispered. Without thinking, he scooped her into his strong, reassuring grip. Maddy nuzzled into the warmth blindly as her dreams calmed into a less frightening one.
