The rest of SG-1 walked into the room, Sam was sitting at her desk in the lab trying to work out a new weapon, which would be a permanent power source. It wasn't going well because she wasn't feeling well today, none of the team knew about this so she continued to keep it a secret.

'Hey Sam how's it going?' said Daniel he was in a happy mood after he had cracked the symbols from a new artifact. When Sam didn't answer Daniel thought something was wrong but he didn't say anything just incase.

'Yo Carter' said Jack

'Oh sorry, sir I didn't hear you come in I was distracted'

'You ok' said Jack.

'Yeah fine, I'm a bit busy at the moment would you mind coming back later'

'Sure' said Daniel

They all began to leave, Sam hoped they would hurry she hated being sick as well as other people being there when she was ill. They were all out on the room when Sam attempted to get up. Jack came around the corner and was going to ask her if she wanted anything to eat when he saw her swaying.

'Carter are you sure you're ok' he said

'Erm yeah I'm fine'

He knew she wasn't, he began to walk towards her when Sam suddenly collapsed, her body went limp, Jack tried to get to her before she hit the floor but he couldn't, she ended up hitting her head on the table.

'Carter, Carter wake up'

He left her and decided to call for a medical team, just then the whole base went black, the power had gone, Sam would have been able to tell them what had happened.

It had been two hours since the power had gone off and nothing was to be heard from anyone outside the room, either there was an infiltration or a virus. One thing was for sure; he couldn't get Sam any help. The bleeding had stopped but there was no sign of her waking up.

Just then she started to move, Jack had put his jacket under her head so that it was comfy but other than that there was nothing he could do.

'Huh' said Sam as she came back to the conscious world. 'What happened?'

'Well you collapsed and hit your head on that trusty stool of yours' he said.

'No not that, I meant the power' Sam said looking very confused.

'I was hoping you could tell me, the power went out just over two hours ago, that's how long you've been out for.'

Jack walked to the other side of the room to get her laptop, he thought she may have needed it, Sam had her own ideas, she got up fast but soon regretted it.

Jack said, 'what are you doing?' before she could reply Sam had lost her balance and had begun to fall, Jack leapt and grabbed her, this time he managed to catch her and put her down gently.

'You can't move, we don't know what is wrong with you'

'I have to otherwise this situation is not going to sort itself out' she said, it was barely heard if anyone else was there it wouldn't have been.

Jack helped her sit up but didn't want to move her anymore than he had done, and passed her the laptop. She started to look at all the information just before the power had gone out and found something.

'Sir, it's a virus'

'I knew it, what's it doing?'

'It has rerouted every bit of data in our files and is slowly sending it through the stargate'

'Ok so what can we do?'

'We need to get out of here for a start, I need to get up to that control room, have you got C4 with you?' she said

'It isn't something I would normally carry around with me, so no' he said with humor in his voice

'Wait a minute, there was something around here which I wanted removed from my lab, it was a highly explosive, its...ah ha here it is' she had to grab onto the side of the cupboard, the loss of blood had been really hard on her. Luckily Jack had realised what was happening and ran over to get the device,
