River
I ran as fast as I could, but I still couldn't keep up with The Doctor. I wasn't big on cardio back in my jail cell, and it was working against me now. On our heels was the entire population of a sack of galactic mutant spiders, all twelve feet tall new-born. It wasn't really their fault. They were just hungry, and we were the only food in the building. We hoped.
"Run faster!" yelled The Doctor. He was about ten feet ahead of me, and slowing down to stay by me. It was hard to get purchase on the slippery industrial floors in my felt bottom boots. I kicked them off as I ran, praying I wouldn't trip. Luckily, The Doctor had a hand on my elbow, and I managed to get them off without falling on my face.
I quickly got ahead of him, and ran faster than I ever had before.
"Brilliant job, River!"
"Thanks sweetie." I smiled as I ran. We were holding hands, and I was looking into his eyes, and he into mine. Its not our fault really, that we weren't paying attention enough to notice when something darted out in front of us.
"Excuse me!" screamed the thing we ran into. Well, man would be a more proper term. He had messy hair, and was wearing a long over coat.
The Doctor grabbed his hand too, and pulled him along behind us.
"I say, what is this?" The man yelled as he was towed behind us.
"Listen, if you could just run, that would be great." I told him. He looked confused, but then he looked behind at what was following us. For a moment, he looked terrified. But then he looked excited. Genuinely excited.
"Jolly good!" he yelled, and then we all ran for all we were worth.
Once we were back inside the Tardis, The Doctor locks the doors.
"Right then." He turns to look at the tall man. "What's your name then?" The man, who seems to have had a slight shock, (as many people who enter the Tardis for the first time do) looks up at him.
"Holmes." He says. "Sherlock Holmes."
