Author's note: First of all, I apologize for the glaring errors in previous chapters. I finally reread them and realized there were some pretty awful typos. Hopefully I have corrected them all, but please let me know if you see any that I missed. I'm still working without a beta… Oh, and I finally got around to making an actual summary for this story. The previous summary was rather vague…

And without further interruptions from me, here's the next chapter.

Chapter 5: Betrayal

Dr. Weir stood at the balcony of the control room. The report she had been reading was temporarily forgotten as she stared at the Stargate below her. She always felt uneasy sending people out on missions. And there were currently three teams offword, including Major Sheppard's team.

Glancing at her watch, she was surprised to see it read 1:47. She hadn't realized it was that late already. None of the teams were due back until later that day. But Elizabeth knew she wasn't going to get much sleep tonight. Something was… off… but she hadn't been able to find out what was causing her feelings of uneasiness. She had just decided to head back to her office to finish looking over some reports when she heard a voice call out to her.

"Dr. Weir, I have something I think you should see."

She turned to find that the voice belonged to Dr. Kavanaugh. Lost in her thoughts, she had completely forgotten that she wasn't the only one occupying the control room at this late hour. The scientist and several technicians were currently running a system diagnostics on their jury-rigged computer system that allowed them to operate the city.

Normally, Dr. McKay would be overseeing the work, but since he was currently offworld, Dr. Kavanaugh had volunteered to do it. She suspected his motives weren't entirely altruistic. The man was always trying to demonstrate his superiority. But she had dealt with his ego in the past and she felt they had finally come to some sort of understanding. While she valued his opinion, she was still the one who ultimately made the decisions.

Elizabeth frowned as she walked over to where the scientist was standing in front of one the laptops connected to the Ancient control panel. They were supposed to be running a routine maintenance program. She hadn't really expected them to find anything important, which made her worry even more. "What did you find?" she asked as she stared at the diagnostics information being displayed on the screen. Nothing looked out of place to her, but then again she only had limited knowledge of this field.

She was shocked to suddenly feel the barrel of a gun pressed up against her head. But she was even more surprised to see who was holding it. She had always prided herself on taking the time and effort to get to know the people she worked with. That was especially true now that they were stranded in another galaxy with no way to contact home. She thought she had everyone figured out: what motivated them to do what they did, why they had agreed to come on this trip to explore unknown worlds. But everyone makes mistakes. She just never thought she could misjudge someone so completely. Who would have thought Kavanaugh would do something like this?

"What are you doing?" she asked, amazed that her voice sounded so calm when she was shaking inside.

"What's it look like I'm doing? I'm relieving you of command."

He then shifted his gaze to look behind her. He pulled her back from the monitor until she was standing in front of him, the gun still firmly pointed at her head. His previous action had not gone unnoticed and several security personnel were warily pointing their weapons at the two of them. "Put your weapons down." The unspoken threat hung in the air.

Elizabeth nodded her head to indicate that they should comply with his requests for now. She then watched as he reached with his free hand and typed a few commands on the keyboard. A program activated but it didn't appear to have an immediate effect. At least, it didn't affect the control room.

"I don't know what you're hoping to accomplish. You're completely outnumbered."

"Then I guess I should even out the odds." Just then, the Stargate sprang to life. "Right on time," he mumbled before forcing his captive to follow him over to the monitor by the dialing device. She could only wonder at how the screen could be registering Dr. Kavanaugh's identification code before he was lowering the shield to allow the visitors to enter the city.

Her list of surprises only increased when she saw who had just materialized from the event horizon. She was relatively certain she could have handled a small internal coup. But this had just escalated into something much larger.

"Dr. Kavanaugh, I see you've successfully completed your end of the bargain," Koyla called out as he motioned for his troops to secure the area. They met with little resistance since the security forces had already been forced to disarm themselves. He then ascended the stairs to join the two doctors in the main control room.

"You've been planning this for a while," Elizabeth stated to the man currently holding her hostage.

"Actually," Kavanaugh replied, "they were the ones who approached me."

"I presented him with an opportunity he could not refuse," Koyla added.

"An opportunity to betray his own people?"

"You wouldn't understand even if I explained it to you," was the reply from behind her. He then turned his attention to other matters. "I cut the power to the rest of the city. All the doors are sealed, but there might still be some people caught in the hallways. You should send some of your men to search the area."

Elizabeth watched as the Genii commander briefly narrowed his eyes in annoyance. Then he issued the order for his men to do as requested. But in that moment, she had already started to formulate a plan.
