Sorry this took so long; I went and saw "The Dark Knight Rises" on Thursday night and there was a festival in town this weekend. Now, I'm in "The Sound of Music," and we're in the middle of Tech Week (Hell Week, as we call it). I'm going to finish this up (And post my Sherlock/Criminal Minds crossover challenge) as quickly as possible.

Spoilers for Doctor Who episodes "Blink," "The Time of the Angels," and "Flesh and Stone" (3x10, 5x04 and 5x05).

I don't own Criminal Minds or Doctor Who.

The party of five was sitting in the kitchen of the apartment, plates of Chinese food spread out around them. Only a few minutes ago the conversation had been on much lighter topics, such as the Doctor's adventures and his admiration for human food.

"This is delicious!" the Doctor crowed.

"And fattening," River added.

Unable to control herself, JJ giggled. "I have a friend who can eat this stuff, and he still looks like he hasn't eaten in weeks."

"I would kill for his metabolism. I would." River replied.

"No talk of killing people during dinner, River," the Doctor added. "That's not the way to introduce JJ to our stony friends." River rolled her eyes as he turned away from the table, stood and fiddled with his sonic screwdriver. It was a moment before he spoke again.

"They're called the Weeping Angels," the Doctor began. "They're very old creatures, not to mention dangerous."

"Dangerous?" JJ asked, confused. "But they're stone! They're statues I saw at a Gertens store this afternoon!"

"Exactly!" the Doctor replied. "They only want you to think they're harmless. That they're simply stone. But then you turn away. Then you blink, and suddenly you realize that you're in more danger than you think." And when he said 'blink,' the Doctor snapped his fingers, making JJ and Amy jump slightly.

"The thing about the weeping angels is that they're quantum-locked," River continued. "When you're looking at it, it appears to be stone. Well, it is stone, literally. A harmless garden decoration, like you said," she nodded to JJ, who was staring at her. "But when you look away, it becomes a killing machine, capable of taking out many, many people."

"That's why you have to keep an eye on them," Amy added. "But don't look them in the eye or else it'll get inside your head."

"And most importantly, an image of an angel becomes itself an angel," River supplied. "If you see a weeping angel on film, in a picture or any other visual form, it can get you. It'll reach right out of the screen or frame and try to kill you."

"They're also called the Silent Assassins," the Doctor concluded. "Usually they send their victims into the past and feed off the potential life energy the person leaves behind. Although they can just kill you in your own time. But they love energy. Anything that gives it off is a potential food source. People, lights… even my ship."

"Ship?" JJ asked.

"The TARDIS," Rory announced.

"Time And Relative Dimension in Space," the Doctor said.

"It's a space ship?" JJ was in awe.

"And a time machine," Amy added.

"So, you really went to 1969?"

"And we went to 2020, alien planets in other galaxies, Venice in 1580, the end of the universe, 18th century pirate ship…" Amy rattled off.

"Any time, and any place," the Doctor confirmed.

"So you've met famous people in the past?"

The Doctor nodded.

"Charles Dickens?"

"Brilliant man, but a bit full of himself," the Doctor replied

"William Shakespeare?"

"A bit of a romantic, and quite possibly bisexual," the Doctor flipped his sonic screwdriver into the air and caught it.

"Really?" Amy asked.

"He propositioned me!" the Doctor yelled.

Marilyn Monroe?"

"Wanted to marry me," the Doctor smirked cheekily and River smacked him.

"Van Gogh?"

"Astounding mind, but odd."

"Einstein?"

"Best friends!"

"Churchill?"

"Been there, done that! We keep in touch, too!"

"Aren't we getting a bit off subject?" River asked tersely.

JJ sat there, trying to digest all this new information.

"It's a lot to take in," she admitted, standing. "I can't believe there's such a thing as aliens, especially stone angels that look like they're weeping… is there any way to kill them?"

"You can't kill a stone," the Doctor admitted. "But I have an idea. My only concern is that innocent lives might be lost."

"And you don't want that, right?" JJ asked.

The Doctor nodded. "The people who work with you will go on to many great things in the future. They will carry the banner that will strike up a new feeling of brotherhood within the confines of humanity. They will cure ills, save lives and help your world to grow. They will do things, and even see things, that will change the world and give this planet something that hasn't been felt in many years: Hope. They will bring you hope again."

JJ nodded, staring at the Doctor. "What do I have to do?"
