Sick. It was sick, in the worst possible sense of the word. All the bodies, the suffering. It was repulsive; everything that Chance hated about human nature. She could feel the pain from the flesh, like a swarm of bees raging in her skull, and she wanted to scream.

"What do we do?" She asked, because she needed there to be a solution, but for the life of her she couldn't see it.

The Doctor was thinking, mind racing like a fast-moving stream. Chance allowed herself to be lulled by the swiftness of his thoughts, then she put up her walls and retreated behind them, barricaded in a quiet place where she could think.

"What do you mean they've got everything?" Asked Rose, "Why would anyone do that?"

"They're lab rats," Said the Doctor, "No wonder the sister's have got a cure for everything – they've got the ultimate research laboratory, a human farm."

Cassandra nodded like that was alright to her. Rose looked around again, horrified.

"What do we do?" She repeated Chance's question as if it were a prayer.

"Nothing," Said a timid voice from behind them. They spun to look. The cat averted her eyes shamefully under their searching gazes, "We've helped so many people –"

"This is helping?" The Doctor gestured around at the rows and rows of cells, "People are dying, Novice Hame."

"And others are living because of their sacrifice!" Said Novice Hame, "Don't you see? It's for the greater cause." She didn't sound terribly convinced.

The Doctor opened his mouth to speak and Chance's hand flew to the arm of his jacket. She gripped it, hard, and the Doctor looked down at her in confusion.

"Novice Hame," She said, "You know what you're doing is wrong."

"How can it be wrong?" The nun insisted, "Think of all the lives we've saved; all the people who are healthy and happy, because of us!"

"And we applaud you for that!" Chance clapped her hands briskly for extra emphasis, "But Novice Hame, you've made these people your test subjects. You keep them sick and imprisoned their whole lives. If you truly think that's worth it, go ahead, do… whatever it is you think you need to do. Or, maybe, you can come with us, help us find a way to end it once and for all. We can finish this. Really, we can, but it's up to you."

Novice Hame buried her face in her paws, "It wasn't supposed to be like this."

"I know," Said Chance.

"I always wanted to help people, I –" She shook her head, "I can't betray the sisterhood."

"So don't," Said Chance, "Give us 10 minutes, 5 minutes, whatever you can. We'll fix things." She looked cautiously up at her father for approval. He gave her a weak smile, "We'll do our best, anyway."

Novice Hame collected herself, nodded without meeting anyone's eyes, and strode out of the room.

Rose released a breath she didn't know she had been holding. Cassandra considered the latest development. It seemed she was running out of time to execute her plan (not that she exactly had a plan, but she wasn't just going to sit idly by while these fools cheated her out of her bribe money). The Doctor and Chance were looking at each other.

"I was going to shame her," He said, honestly.

Chance blinked. She had suspected as much, but she found it was entirely different to hear him admit it aloud. She opened her mouth to speak.

"Your idea was better," He said before she could. Chance flushed a little with pride, then cleared her throat and tried to regain her focus.

"5 minutes," She reminded him, "What's the plan?"

The Doctor smiled, "I have no idea. Isn't that just the best?"

Of course it was. What other option was there?
