"Doctor?"

He jumped up and pressed his face against the bars, trying to see who was in the cell next to him.

"Hannah, is that you?"

But it wasn't Hannah staring back at him from the other cell's bars.

"River?"

"Doctor, it IS you! What are you doing here?"

She looked a lot younger than he remembered, "Never mind that, what are you doing here?"

She smiled her patronizing little smile, "Looks like neither of us is going to tell the other how we got here. Question is, how do we get out?"

The Doctor paused, "Well I've got a friend..."

River looked around, "I don't see them anywhere."

"That's because she's probably being tortured as we speak."

"Oh."

"Yeah."

"So, what are we going to do?"

The Doctor sighed, almost defeated, "I don't know. No TARDIS, no screwdriver, nothing. Hannah's probably dead or imprisoned, and Fenn's most likely being tortured right now. To be absolutely honest, River, I've got nothing."

River spoke up, "Why tortured? What did she do?"

"Well, as far as I can tell, she's worked for the agency for quite a few years. They gave her a mission- to arrest me, but she wasn't going to do it. They must have hired the Judoon to take Hannah as ransom- she was Fenn's friend, or partner, or something. Anyway, Fenn thought that if she arrested me and turned me in, she'd get Hannah back."

River shook her head, "And Delven threw them both somewhere dank and evil."

The Doctor nodded, "Do you know where they could be, River?"

She smiled, "I would say spoilers, but I don't think it'll affect your timeline too much, so I can tell you. There's this- thing- that Delven threatens us with sometimes, an awful thing."

"What is it, River?"

"It's a crack."

"A crack?"

"It's no ordinary crack, Doctor. It's a crack in the skin of the universe- two pieces of space and time slammed against each other. Delven takes the bad cases and-" she paused.

"What, River? Tell me!"

"He makes them look into it, Doctor. The whole of the universe pouring through your mind- it hurts beyond telling, apparently. Personally, I was never put in front of it, but that's what I've heard."

The Doctor sat back in his cell, desperate. Everything was falling apart as he sat and watched- nothing seemed to be going right. He sighed, and was about to at least try and get some sleep, when a phone rang. A guard came to answer it, "Cell 46... The Doctor? Do you mean Doctor Song?"

He started to get up, but River shot him a look and ran up to the bars, "Give me that. Seriously, just give it to me. I'm entitled to phone calls."

The guard passed it to her, and she turned away, "Doctor?!"

The Doctor turned away, wondering why in the universe River didn't want him to take the call. He was about to sit down again, when he heard it.

"Psst! Doctor!"

He almost sighed with exasperation, and turned towards River's cell, only to see Fenn grinning at him from the edge of his cell bars furthest from the guard.

***

Fenn ran down the corridor, listening out for signs of pursuit. She was struggling not to laugh at the stupidity of the whole situation. Had Delven forgotten that she knew the engineers who had designed the 'vortex' room, as they called it? Apparently he had. She could remember, vividly, watching them build the fault into the chair. It had taken her only a matter of seconds to undo the shackles and slip out, once Delven and his cronies had left her for dead. Apparently they had found it less entertaining than usual, considering she hadn't begged for mercy like the others did. Oh sure, she had screamed, but she had never cried out for help.

She winced as the pain began to return, almost collapsing under its overwhelming pressure. She hadn't realised what a monster the agency was until now. She kept running through the pain, knowing she had to get to the Doctor before it was too late.

It had been quite a few years since she had last been in the facility, and it took her a while to recall where the cells were- but as she ran it freshened in her memory, and she began to remember details.

Delven's face floated through her mind, "The Doctor is to be arrested immediately on sight and his TARDIS delivered to the agency, where it shall be kept in the storage facility 9. On arrival in HQ, you are to take him immediately to cell 45. You are not to speak with the target. Understood?"

She regretted her answer. Oh, how she wished she had of refused then and gone to find the Doctor herself, to warn him. She smiled grimly at the thought of what she would do if she ever met up with Delven again.

She ran down the corridors, finally coming into the Stormcage Facility itself. She ran passed the cells, counting as she went, "38, 39, 40, 41, 42, 43, 44, and 45!"

She skidded to a halt when she saw the guard outside cell 46. Doctor River Song was in there, if she remembered correctly. Fenn could hear her talking, and guessed she was on the phone. The guards weren't permitted to talk with the prisoners outside of bare necessity. She smiled. The guard was new. What a pity he had to be on duty when she came a-calling.

The Doctor stood facing the back wall of his cell. Fenn couldn't help but feel sorry for him- he looked utterly defeated. She walked up to the bars, and whispered playfully, "Psst! Doctor!"

The look on his face would have sent her into fits of laughter had it not been for the gravity of the situation. He came up to the bars and whispered, "Fenn? What are you doing here? How did you get out?"

Fenn just grinned, "Oh, that's a story for later. In the mean time, let's get you out of here."

"How do you-"

She put a finger to her lips and smiled, indicating the guard, who was still watching River. The guard spoke, "Doctor Song! Are you finished with that?"

River turned to face him, "You're new here, aren't you?"

He nodded, "First day." Fenn couldn't help but grin.

River stepped up to him, "Then I'm very sorry," and pulled him in for a kiss.

Fenn snuck up behind him, and saw her chance. She grabbed one of the two guns that every agent carried out of his holster, and gently pulled his vortex manipulator off his belt. River released the guard once she knew Fenn was done, and the guard staggered back, in a trance. Fenn smiled at River, "Hallucinogenic lipstick?"

River nodded, "Manipulator?"

Fenn chucked it to her, "Take it. I've got another mode of transport. Besides, you need to go and steal a painting."

River didn't even ask how she knew, and began typing coordinates into the manipulator. The guard started to come around, so Fenn ran over to the Doctor's cell, swiping the poor guard's keys while she was at it. The Doctor had to ask, "How do you know what River has to do?"

Fenn grinned at him again, "I watch the show."

"Right."

Just as Fenn opened the door, an alarm klaxon went off. She swore, "Damn it! They must have put triggers through here. River teleporting out must've set them off."

The sound of footsteps rang through the corridor. Fenn grabbed the Doctor's arm and yelled, "RUN!"
