Spacegates and Starships

A Stargate SG-1/Doctor Who Crossover

Summary: A chance encounter on a random planet leads a pair of intergalactic wanderers straight into the heart of Stargate Command. Events quickly become complicated in a hurry. And there's something not quite right about Lab 32…
Disclaimer: Both shows absolutely in no way belong to me. I just decided to squish the two together for my own amusement.

Note: This chapter was extremely hard to write. Mainly because it was the chapter I completely forgot about… My outline sorta skipped over certain details…like how they got from Point A to Point B…

Chapter 6

The entire control room staff was shocked when the power suddenly shut off. A few seconds later, the emergency system activated and the room was once again bathed in light. "What just happened?" Daniel asked.

But Sam was already deeply engrossed in finding an answer. There had been no indications from the system that a power failure was about to happen. And so far she could find nothing that pointed to an explanation. It was possible it was another glitch. But she found it hard to believe that two random errors would occur so close together. No, something was definitely wrong and she was determined to find out what.

"What's going on?" General Hammond asked as he entered the control room. He was followed by the other two members of SG-1. He was slightly annoyed that he only got a few shrugs and baffled looks in response. "Major?" he asked, hoping she had a grasp on the situation.

"I'm not really sure sir," she replied, her attention never leaving the screen. "I think there was a power surge, but I'm having trouble tracking the origin. Someone's modified the data logs."

"Someone got into our system? Or is it a computer virus?"

Sam was getting increasingly frustrated with her lack of progress. "I don't know. I'm still waiting for certain systems to come back online."

The control room became even more crowed with the arrival of two more people. "What's going on?" the Doctor asked, unconsciously mimicking the general's earlier question. Realizing something was wrong, he and Rose had immediately headed for the center of the action. His curiosity just wouldn't let him ignore trouble.

"We're still trying to figure that out," the general replied.

"Do you know you have a bug problem?" Rose asked. Everyone stopped and turned to look in her direction. She was currently staring at a spot on the ceiling. Following her gaze, they were shocked to see a metallic insect-like object clinging to the roof. It looked remarkably like a giant centipede.

"What is that?" Jack asked. He was pleased to see that all weapons in the room were already being pointed at it. The bug didn't look particularly dangerous, but he knew from experience that looks could be deceiving.

"Something else that shouldn't be here," the Doctor muttered as he flipped through several settings on his screwdriver.

Realizing that it had been spotted, the metal bug began scurrying towards the nearest air vent. But it didn't make it very far. The Doctor quickly scrambled onto a nearby chair and aimed his screwdriver at it. Its legs immediately froze up and a second later the bug fell to the ground, the metallic clunk echoing throughout the silent room. After scanning it for any further signs of activity, the Doctor picked it up to examine the design.

"You've seen this before?" Daniel asked.

The Doctor simply nodded in reply. What was twenty-fifth century technology doing here? Then he realized that everyone was waiting for some sort of explanation. "It's a scavenger bug. It was designed to scan for certain pieces of technology and then transmit the location." He had only ever seen them used for salvage operations, such as when a ship crashed. They were much faster than having to search a large area by hand.

"You're saying someone sent this thing to spy on our technology?"

"You may have a larger problem than you think. It may have started as one, but their numbers multiply pretty fast. We need to find the nest."

"And how would you suggest we do that?" the general interrupted. He was tired of all these little problems popping up. He wished his base would run smoothly for once.

In response the Doctor looked over at Sam. It only took a moment before she caught on. "The power surge. Wherever it started, that's where we'll find the nest."

"What do they have to do with each other?" Jack asked, hoping he wasn't the only one left out of the loop. Then he immediately raised his hand to stop Sam. "In three sentences or less Carter."

She closed her mouth and paused to start again. "The bugs are mechanical, so it's reasonable to assume that they need a power source. And it takes a lot of power to feed a full nest of bugs. I'm guessing the whole nest tried to recharge at once which caused the power failure."

"So if we find the power surge, we find the bugs," Jack concluded for her.

"Exactly sir." She then returned her attention to her screen, once again rapidly typing commands.

"So, we have step one in place," Jack said as he turned to address the Doctor. "How do we stop these things once we find them?" He had a feeling he didn't really want to hear the answer once he saw the mischievous look on the other man's face.

One hour later, SG-1 (minus Sam), the Doctor and Rose were assembled in front of their target. Sam was in the control room preparing their attack. Of course, they had all been rather surprised to learn that the power surge had come from Lab 32. Sam had tracked the glitch from earlier to a terminal located in the lab. Someone had rerouted a large amount of power to that section of the base.

Jack activated the door and then motioned for Teal'c to enter first. He quickly followed, scanning the opposite side of the room. "Clear!" he called out. That was the cue for the other three members of the group to enter as well.

"There's nothing here," Daniel commented. He had to admit, he had been expecting some giant nest with creepy metallic insects crawling all over the room. But the lab looked exactly the same as when he had left the Doctor and Rose there with Dr. Reed. Speaking of whom… "Where's Dr. Reed?"

"He was here when we left," Rose replied. But the room was clearly empty. "Maybe he went on a break," she suggested. He had looked rather frazzled when they left.

The Doctor decided they would worry about the man's location later. Right now they had a task to do. "We didn't check behind that door," he said as he pointed at the partially hidden doorway he had noticed earlier.

They carefully moved the metal panels and then prepared to enter. Jack scanned his access card and the door slid open to reveal nothing but darkness. Taking a cautious step inside, Jack quickly scanned the room with the light mounted on top of his weapon.

"Gross," he commented, moving slightly to the side to allow the rest of the group to enter. The small beam of light had revealed a sea of metal parts, some already formed into legs and heads. It looked like a small graveyard of insect parts. But in the center of the room there was a mass of wires and cables leading to dozens of fully assembled bugs. As the beam passed over one particular row, the insects began to activate. Their legs began to move and they set about detaching themselves from the wires.

"Carter, we found the nest. How's it going on your end?" Jack relayed into his radio.

"Almost done sir," was the only reply.

"Jack, you might want to tell her to hurry…" Daniel said he as he took a step backwards. By now, almost all of the insects were in motion, several having already managed to break free from the power supply. The Doctor used his sonic screwdriver to disable a few that crawled too close for comfort. Despite his assurances that the bugs really were harmless to people, no one really wanted the things crawling on them.

In a rather anticlimactic ending, the bugs suddenly stopped. All motion ceased and the indicator lights gradually faded to darkness. "Did it work?" Sam's voice asked over the radio.

"Yeah, I'd say it worked," Jack replied. He had been surprised at the Doctor's response about how to stop the bugs: Do you have any dog whistles? Luckily, the SGC had the next best thing, several super computers and a base-wide intercom system that would allow them to broadcast any sound frequency they wanted. Apparently, the bugs had been designed to obey certain commands issued by high frequency sound waves. All they had to do was play the stop command. Needless to say, this was probably the easiest mission SG-1 had ever completed.

Unfortunately, their celebration was soon cut short. "Nobody move or I'll kill the girl," a masculine voice called out from behind them. Everyone turned to see Dr. Reed holding a gun to Rose's head.
