It had just turned dusk. River found herself in the middle of the city. She had made her way through an underground maze to get to the castle that she was sure the Great Intelligence was in. River was in the throne room facing an empty chair full of cobwebs. A swirl of smoke was in the seat. It made River feel sick and tired, but she was going to face the enemy of her husband and take him down.

"So you've found me," a voice whispered. It didn't match the voice the other doctors had heard in their meeting devised by the Captain.

"I have," River replied. "Though it wasn't by my efforts that I've found you. You can thank," but River was cut off.

"The impossible girl," the Great Intelligence replied. "I am well aware. The coordinates were given to her by the doctor, though not by any doctor you've met."

River shook her head. "Your tricks won't work on me."

A sudden burst of wind rushed towards River knocking her over causing her gun to be tossed aside. "No tricks here, Melody Pond. I have nothing but knowledge."

River stood up. "If that's so," she began wiping away blood that had come from her lips, "then can you tell me where it is I come from?" There was silence. "I thought as much. You see I come from the greatest library in the entire universe. It's my home, really. You feel you are knowledge incarnate when in fact you know very little compared to myself."

"Is that a challenge?" the Great Intelligence questioned.

"I like a challenge just as much as the next person, believe me," River said, "but I prefer vengeance."

A malicious laughter could be heard from the swirling smoke. "As do I, Pond, as do I. But what for in this case? Your beloved doctor? Your parents?"

"My reasoning is my own," River stated. "However something I learned while I was in the library, courtesy of my dear friends, was of my husband's enemies. Each and every one including yourself."

"I'm a popular entity," the Great Intelligence said. "It's no surprise, really."

River reached for her gun, facing the vapors. "Funny thing about my gun. I have an extension on it that when used on pure vapors," she paused to press a button her gun that made it extend almost half a foot. She then shot it at the vapor. "As I was saying, this extension allows the electricity to pulsate through an entire vaporal cloud causing whatever entity may or may not be inside, to die a quick yet very painful death."

A deafening roar could be heard from within the cloud that was the Great Intelligence. The building River was in began to collapse upon itself. Rubble was falling down causing River to dodge to avoid each one. "Are you satisfied with yourself?" the doctor asked. He rounded a corner grabbing River's arm. "Just had to go and face the Great Intelligence yourself. Want to know why I never killed the Great Intelligence?"

"You're too noble," River said. An explosion could be heard from the room the two had just left.

"Wrong," the doctor replied. "The reason I never wanted him to die was because the moment he truly dies whatever area he is in implodes upon itself causing a giant hole to form."

River's face went from annoyed to worried. She grabbed the doctor's wrist and began to run as another explosion could be heard. "That explains quite a bit."

"It does?" the doctor asked.

"Yes, it does," River said.

"Come on you two!" Captain Jack exclaimed. "Stand on the mat!" The doctor looked down and saw a rectangular metallic mat.

"Where did you get that?" he questioned.

"Later!" River said as she pushed the doctor onto the mat.

"Brace yourselves," Captain Jack said. He placed his arms around the doctor and River. The three felt a force pulling them away from the abandoned city back to the T.A.R.D.I.S.

"A portable transmat," Captain Jack explained once they were back on board the T.A.R.D.I.S. The doctor set coordinates back for London, England. Jack picked up the mat and it collapsed into a small wallet-sized version. "Also collapsible." River rushed out of the antechamber. "Where is she going?"

"I couldn't quite tell you," the doctor said. He then smacked his hand against his forehead.

"Are you alright, doctor?"asked Jack.

He nodded. "A bit of a repercussion for melding minds with my previous incarnations. It doesn't happen very often."

"You'll be okay, right?" Jack asked.

"Oh yes," the doctor said. At last the T.A.R.D.I.S. stopped in current day London.

"What brings us here, doctor?" Donna asked. She was awake and was leaning against a wall frame.

The doctor faced Donna. "Are you alright?" he questioned.

Donna nodded. "The paradox off balanced the meta crisis," Donna explained. "I had one window opportunity and apparently that was to take place in 1930s Manhattan."

The doctor nodded. "Where's River?"

Donna inclined her head backwards. "She's with Clara right now, going at it."

The doctor rushed past Donna who simply looked at Captain Jack who merely shrugged his head. The doctor followed the screaming. River was waving her arms frantically yelling at Clara. "River enough!" the doctor shouted. "Clara saved my life, surely you would be grateful?"

River shook her head. "It's not that," she said. "Clara knew what coordinates to get us to Italy. How?"

The doctor looked to the T.A.R.D.I.S. "She must have shown her," the doctor said. River relaxed her tenseness.

Donna approached the group with Captain Jack at her side. "Doctor. Jack here is going to take me home. I need to make sure my mum and grandfather are alright." The doctor nodded. She grabbed the doctor's hand. "It was good to see you again, even if it's with a new body."

"I'll be making regular house calls, Donna Noble," the doctor said. She nodded and departed with Jack.

"Where to?" Clara asked the doctor keeping her eyes off of River.

The doctor looked down. "I need time to rest. My previous regenerations are at ends with one another right now." He rattled his head to drown out the noise. The doctor left River and Clara alone once more. Clara left to the console to check on the date of their arrival while River went to wander. The T.A.R.D.I.S. was quiet.

Clara had forgotten about the Sontaran that was being held in an invisible holding cell. She was startled so much by its sudden stirring that she fell on the console igniting a destination that was as yet unclear. The doctor and River came running out to see why the T.A.R.D.I.S. was revving up.

Clara tried to explain but it came out in sobs. River placed her hand on Clara's shoulder trying to show her that she did care for Clara, despite everything. "Doctor, look at the screen," River said. Her face grew in fear.

"Quickly River, you must go!" the doctor shouted. She nodded closing her eyes. She dematerialized before the eyes of Clara and the doctor.

Clara shouted at River. "Where is she going?" she asked turning to the doctor.

"Back to the library," the doctor said. "Where we are heading she cannot follow."

Clara looked to the screen but did not recognize the image upon it. "What is that?"

At that moment the T.A.R.D.I.S. came to a grinding halt. The doctor snapped his fingers and the Sontaran disappeared. The doctor had moved him to a holding bay down below. He went to the door and opened it up revealing an even bigger space than that of what the T.A.R.D.I.S. contained. "Welcome Clara, to Warehouse 13."

Clara exited the T.A.R.D.I.S. Her mouth was agape. "Where are we, exactly?"

"Well we are exactly seven miles from Univille, South Dakota," the doctor explained. Clara looked around facing millions of shelves with odd baubles upon them. She reached her hand out but it was slapped shortly after by the doctor. "Rule number one here is touch nothing unless given prior consent."

"What is this place?" Clara asked.

The doctor smiled. "As I said before this is Warehouse 13. The agents here collect artifacts across the world that cause certain events to transpire. These artifacts often need a living host to be activated, though not always."

"These events, are they good or bad?" Clara asked.

"Precisely," the doctor said. He looked around. "It's been years since my last visit. The T.A.R.D.I.S. must have kept the coordinates and you hit a button that brought us here." He looked up and pointed. "Ah yes, there's my old friend's office."

"Old friend?" Clara questioned as the doctor made his way through the maze of shelves.

He nodded. "Artie Nielson," he replied. "I've helped him over the years." He came to a stop and turned down an aisle filled with television sets. "It's not often he needs my help, old Artie, but it seems the T.A.R.D.I.S. has brought us here for a reason."

Clara nodded. "Right." She looked around. "You think a place this big would have some sort of alarm system."

The doctor turned to face Clara. "It does, probably the biggest you'll ever encounter. However being who I am," he said raising his hands up in the air.

"The same rules don't apply to you," Clara said.

The doctor nodded. They then found a ladder. "After you," he said. Clara climbed up the ladder and found herself facing an office. The doctor was soon after and they both entered the office. The lights were off. Once inside they were turned on and two guns were pressed against the doctor and Clara's back.

"Don't move!" shouted a woman. "Who are you and how did you get in here?" The man that had his gun pressed into the doctor's back seconded that notion.

"Are you sure they remember you?" Clara whispered to the doctor.

"It would appear Mrs. Frederic hired a few new people," the doctor said with a shrug.

The man and woman looked to one another suspiciously. "How do you know Mrs. Frederic?"

The doctor turned slowly. "An old friend, as is Artie."

"Who are you?" the two asked.

"I'm the doctor," he replied. "And I'm here to help."
