Storm: Time Jump

"What's Vashta Nerada?" Donna asked as Teresa tensed, and the Doctor explained: "It's what's in the dark. It's what's always in the dark. Lights!"

He shouted as he turned back to the group of archeologists, taking Teresa with him as he ordered: "That's what we need, lights. You got lights?"

"What for?" River asked, and the Doctor said quickly: "Form a circle. Safe area. Big as you can, lights pointing out."

"Oi. Do as he says." River told her group, as the Doctor removed his coat and began to circle the room keeping Teresa tightly with him.

Lux said to River incredulously: "You're not listening to this man?"

"Apparently I am." River retorted. She the ordered: "Anita, unpack the lights. Other Dave, make sure the door's secure, then help Anita."

Donna stared at the woman while Teresa smiled, and the Doctor lay with his ear against the ground.

River went on: "Mr. Lux, put your helmet back on, block the visor. Proper Dave, find an active terminal. I want you to access the library database. See what you can find about what happened here a hundred years ago."

She picked up her helmet and called: "Pretty boy, girl, you two with me. Step into my office."

The Doctor jumped up as Lux called: "Professor Song," River turned to him, "why am I the only one wearing my helmet?"

She smiled and replied easily: "I don't fancy you."

The Doctor walked over to Dave at the terminal, pulling on his glasses as he commented: "Probably I can help you."

"No, Doctor." Teresa told him as River called again: "Pretty boy. With me, I said. Angel, sweetie, come on."

The Doctor looked at Teresa puzzled, and Donna leaned forward with an expectant expression waiting for the penny drop. Teresa also stood patiently waiting as the Doctor glanced around the room, before he finally realized.

"Oh, I'm pretty boy?" He asked as he pointed to himself and Teresa laughed at him.

"Yes." Donna mocked sarcastically. "Ooo, that came out a bit quick."

"Pretty?" He asked, his face scrunched in disgust, and Donna replied: "Meh."

The Doctor looked torn between disgusted and flattered, when Donna then added: "Though, Terry's definitely a pretty girl."

Teresa smiled although her expression became a little confused as the Doctor said enthusiastically: "Oh, no question about that."

He took Teresa's hand casually once more, making her stare at him, but he didn't seem to notice as he walked after River and yelled at the group: "Don't let your shadows cross. Seriously, don't even let them touch. Any of them could be infected. "

He walked into the office with Teresa, and her face fell as he leant against the desk, pulling her beside him while River dug in her backpack. Teresa hated this part, and it was worse because it was her first time seeing River too. River clearly knew her, and she bit her lip anxiously at possibly causing River double heartache.

The Doctor was watching River curiously as River finally pulled out her battered blue diary, and she said randomly as she began to flip through it: "Thanks."

"For what?" The Doctor asked flatly, and River replied lightly: "The usual. For coming when I call."

"Oh, that was you?" The Doctor asked in surprise, and River raised a brow as she commented: "You're doing a very good job, acting like you don't know me. I'm assuming there's a reason."
