Katherine, The Doctor and Amy were in a Museum, "Wrong. Wrong. Bit right, mostly wrong. I love museums," The Doctor said as they looked around. "Yeah, great. Can we go to a planet now? Big space ship? Churchill's bunker? You promised me and Kat a planet next," Amy said.

"Amy, this isn't any old asteroid. It's the Delerium Archive, the final resting place of the headless monks. The biggest museum ever," The Doctor said. "You've got a time machine. What do you need museums for?" Amy asked. "Why are you complaining? Katherine doesn't complaining," The Doctor said and Katherine shrugged. "Wrong. Very wrong. Ooo, one of mine. Also one of mine."

"It's how you keep score," Katherine said and Amy giggled. The Doctor looked at a square box in a case and walked over to at. Katherine and Amy walked over as well. "Oh great, an old box," Amy said sarcastically. "What is it?" Katherine asked about the box.

"It's from one of the old starliners. A Home Box," The Doctor replied. "What's a Home Box?" Amy asked. "Like a black box on a plane, except it homes. Anything happens to the ship, the Home Box flies home with all the flight data," The Doctor explained.

"So?" Amy asked. "The writing, the graffiti. Old High Gallifreyan. The lost language of the Time Lords. There were days, there were many days, these words could burn stars and raise up empires, and topple gods," The Doctor said. "What does it say?" Katherine asked. The Doctor was quiet for a moment and then spoke, "Hello, sweetie."

The Doctor took out the box and then an alarm was sounding and guards were chasing The Doctor, Katherine and Amy back to the TARDIS.

"So, we went to the museum to steal from it," Katherine said and Amy smirked. "I'm not stealing if, love. I owned it in the first place," The Doctor said with a grin. He plugged the box into the consol.

"Why are we doing this?" Amy asked. "Because someone on a spaceship twelve thousand years ago is trying to attract my attention. Let's see if we can get the security playback working," The Doctor said. The playback showed a woman winking at the camera. "The party's over, Doctor Song. Yet still you're on board," A man said.

"Sorry, Alistair. I needed to see what was in your vault. Do you all know what's down there? Any of you? Because I'll tell you something. This ship won't reach its destination," The woman said. "Wait till she runs. Don't make it look like an execution," The man said. "Triple seven five slash three four nine by ten zero twelve slash acorn. Oh, and I could do with an air corridor," The woman said. The Doctor inputs. "What are they?" Katherine asked. "Coordinates," The Doctor replied before he pulled a leaver.

The Doctor ran and he opened the door. The same woman land on top of him. Katherine and Amy frowned. "River," The Doctor mumbled. They both got up and looked out. "Follow that ship," The woman, River said, "They've gone into warp drive. We're losing them. Stay close."

"I'm trying," The Doctor said. "Use the stabilisers," River said. "There aren't any stabilisers," The Doctor said. "The blue switches," River said. "Oh, the blue ones don't do anything, they're just blue," The Doctor said, annoyed by her. "Yes, they're blue. Look, they're the blue stabilisers," River said.

She presses them and the TARDIS stopped shaking. "See?" River said. "Yeah. Well, it's just boring now, isn't it? They're boring-ers. They're blue boring-ers," The Doctor said. Katherine frowned as she looked at The Doctor and River, arguing like a married couple. "Doctor, how come she can fly the TARDIS?" Amy asked. "You call that flying the TARDIS? Ha!" The Doctor said.

"Okay. I've mapped the probability vectors, done a fold-back on the temporal isometry, charted the ship to its destination, and parked us right along side," River said. "Parked us? We haven't landed," The Doctor said. "Of course we've landed. I just landed her," River said. "But, it didn't make the noise," The Doctor said. "What noise?" River asked. "You know, the noise," The Doctor said.

"It's not supposed to make that noise. You leave the brakes on," River said. "Yeah, well, it's a brilliant noise. I love that noise," The Doctor said as River started to pass him. Her eyes landed at Katherine and she had a big smile. "Hello, River Song," River said. "Katherine Williams," Katherine said. River smiled as she gave her a small bow and walked outside.

"Off we go," The Doctor said. "What are you doing?" Amy asked. "Leaving. She's got where she wants to go, let's go where we want to go," The Doctor said. "Hang on, is that a planet out there?" Amy asked. "Yes, of course it's a planet," The Doctor said. "You promised us a planet," Katherine said. Amy nodded and The Doctor looked at Katherine. He sighed. "Okay, but five minutes," The Doctor said. "Yes!" Amy said with a big smile. She grabbed Katherine's hand and they ran outside.

They saw another woman and she smiled at River. "You took your time, River," The woman said and River smiled. "Sorry," She said and the woman giggled. Then she looked at Amy for a moment, and then her eyes landed at Katherine and The Doctor. Her eyes grew wide for a few seconds and then she smiled. River looked at them all, "Amy, Katherine, Doctor, allow me to introduce my best friend, Rebekah Brenner," She said with a smile.

Rebekah smiled and gave a small bow. "Hello," She said. Katherine, Amy and The Doctor smiled. "Hey," Katherine said and Rebekah smiled at her.

Then they all looked at the crash spaceship. "What caused it to crash?" Katherine asked. "We don't know," Rebekah said. "The warp engines had a phase shift. No survivors," The Doctor said. Katherine looked at The Doctor, who stood next to her. "How did she do that? She just left you a note in a museum," She said about River. "Two things always guaranteed to show up in a museum. The Home Box of category four starliner and sooner or later, him. It's how he keeps score," River said.

"I know," Katherine said with a smile. "It's hilarious, isn't it?" River said with a smirk. Katherine, River, Amy and Rebekah giggled. "I'm nobody's taxi service. I'm not going to be there to catch you every time you feel like jumping out of a space ship," The Doctor said. "And you are so wrong. There's one survivor. There's a thing in the belly of that ship that can't ever die," River said.

"That's what made it crash?" Katherine asked. River nodded and smiled, pressing the device to her ear. "You lot in orbit yet? Yeah, Beka and I saw it land. We at the crash site. Try and home in on my signal," River said. She turned around, "Doctor, can you sonic me? I need to boost the signal so we can use it as a beacon."

The Doctor groaned, but he did it anyway. "Ooo, Doctor, you sonicked her," Amy said. Katherine giggled. "We have a minute. Shall we?" Rebekah asked. The Doctor, Katherine and Amy followed Rebekah and River.

Four small tornadoes kicked up the dust and turn into four soldiers. "Doctor Song, Doctor Brenner. You two promised me an army," A man said. "No, we promised you the equivalent of an army," Rebekah said. "This is The Doctor," River said.

The man shook The Doctor's hand as he spoke to him, "Father Octavian, Sir. Bishop, second class. Twenty clerics at my command. The troops are already in the drop ship and landing shortly. Doctor Song and Doctor Brenner were helping us with a covert investigation. Has they explained what we're dealing with?"

"Doctor, what do you know of the Weeping Angels?" Rebekah asked. The Doctor's head shot up, frowning slightly. Katherine and Amy exchanged looks.
