The Eleventh Doctor stepped out of the Blue Box with a frown upon his face. "River," the Doctor said, scowling at the blonde woman standing before him.

"Hello, Sweetie," River said sweetly. "I knew you'd find a way to come."

"Don't you, hello sweetie me. Correct me if I'm wrong, but you've sent for me to help…you…rescue me?" the Doctor asked, confused.

"That's correct," River said. "I explained the last message went to your previous incarnation and it's him…you…him, that's in that warehouse."

"You realize that my being here threatens to tear a hole in the universe; one the exact size of Belgium to be precise? But since I'm so clever I reinforced the shields and managed not to merge the TARDISes. Did I tell you about the time my TARDIS merged with a previous…" the Doctor rattled off.

"Doctor, that's all very interesting, but we have more important things to think about right now," River interjected impatiently as she led the Doctor toward the warehouse. "Like saving you from those androids! We're running out of time! Do you know what you're going to do?"

"All right, all right. I'm working on a thing."

"A thing?" River asked.

"Yes, a thing in progress. Respect the thing," the Doctor said.

River snorted, realizing the Doctor had deliberately uttered the exact words he had spoken on the spaceship the Byzantium.

"So where did you leave Amy and Rory?" River asked.

"I left them in Paris for a much needed holiday."

"Doctor, you remember Father Octavian and his clerics from our mission with the Weeping Angels on the Byzantium?" River asked.

"Yes, of course I do. I would do anything to change that outcome," the Doctor said sadly.

"Well, Bob's here and he's been helping me."

"Bob! I liked Bob, sacred Bob…scared Bob," the Doctor said cheerfully, but then he remembered what had happened to the clerics and his face revealed the pain he felt at the memory. "Yes, I wish I could have saved them…hmmm…maybe I still can…"

"What are you thinking?" River asked warily.

"I'll tell you later. Now, you see this?" the Doctor said as he showed River the device he had been holding in his hand.

"Yes, what is it?" River asked.

"It's a very small and modified microwave generator that I created. I'm going to use it to create a non-nuclear electromagnetic pulse which I will use against those tin men and knock them on their tin butts," the Doctor said, smiling. "The EMP will create a magnetic field that will damage the electrical elements in their bodies."

The Doctor stopped abruptly to face River Song. "River, listen to me."

"Yes?" River asked.

"It's vital that Bob doesn't see me. Do what you must, but keep him away from me."

"But, won't you need me to help you?" River asked, disappointed she wouldn't be a part of the rescue.

The Doctor smiled. "You will be helping by doing this for me. Do you trust me?"

"Of course. I always have."

"Good. Then I'll see you when this is over."

"All right," River said as she watched the Doctor run toward the back of the warehouse. She sighed heavily and then went to look for Bob.

The Doctor climbed to the roof of the building. He walked gingerly across the metal roof toward the back room where the Tenth Doctor was being held. The warehouse blueprints he had examined before landing displayed there was a skylight on the roof set in the center of the room. It was perfectly placed for what the Doctor was about to do. The Time Lord looked through the glass and saw his previous incarnation lying on a metal bed with his duplicate android lying beside him. He witnessed how forcefully the Tenth Doctor fought against the android who was placing the Chameleon Arch on his head.

"I've told you, the harder you resist against the transference, the more painful the experience will be," Andrew said. "Now, it's time you submit to your new future. Welcome to my army, Doctor."

As Andrew turned on the Chameleon Arch, the skylight above shattered into a million pieces as the Eleventh Doctor's foot broke through the glass. The Time Lord quickly turned on the microwave generator and the electromagnetic pulse exploded over the room. Andrew screamed as the damaging current from the EMP crashed the electrical circuits in his robotic body. The leader of the android soldiers immediately fell to the floor amongst the remaining band of soldiers.

The Eleventh Doctor smiled as he saw the Tenth Doctor look up in shock. He realized the Tenth Doctor wouldn't have a clue as to who he was and he thought it best to keep it that way. He smiled, gave a nod and waved goodbye to his previous incarnation.

The Doctor quickly climbed down the building and found River looking at him in anticipation. "Where's Bob?" the Doctor asked looking around for the young cleric.

"He's gone to bury the android."

The Doctor chuckled. "Brilliant."

"Well?" River asked anxiously.

"Well, it's done. He's safe. And…I know the exact coordinates of where you can find Father Octavian and his clerics. I scanned all of Europe for the priests, and I detected a power source deriving from an Oblivion Continuum."

"What is that?" River asked, concerned.

"It's a bomb created by the Daleks and I would imagine it's one of the clerics who's carrying it."

"It must be the cleric we found dead in the warehouse," River suggested.

"It would have to be the Daleks who are behind this. River, you have about 20 minutes before the bomb detonates. You have enough time to stop it." The Doctor motioned toward the warehouse. "Hurry and get him out of there. He'll know what to do to stop the Oblivion Continuum."

"What? You're not coming with us?" River asked, surprised.

The Doctor shook his head no and smiled. "Remember I mentioned the hole in the universe? Besides, you don't need the two of us for this. You've got him…me…oh, you know what I mean. Listen River, there's something else I need you to do for me," the Doctor said earnestly.

"Name it," River said.

After the Eleventh Doctor gave specific instructions to give to the Tenth Doctor, he entered his TARDIS and moments later the time machine disappeared.

River rushed into the warehouse and found the Tenth Doctor strapped to the table with the lifeless androids strewn on the floor.

"River! Get me out of these straps!" the Doctor shouted.

"Are you all right?" River asked as she undid the leather bands from the Doctor's arms and legs.

"Yes, yes! Who was that on the roof?" the Doctor asked impatiently.

"On the roof?" River asked.

"YES! Was he who I think…?"

"Look Doctor, I don't have time to explain right now but there's a bomb ready to explode and destroy earth! We have to get to it! NOW!"
