A/N; not sure where this is going right now, but if you have any ideas about the ending or what should just tell me and I'll try and add them! And thank you for all your comments:) they are really inspiring and lovely!

They didn't speak throughout the journey back to the hub; hardly even looking at each other. They were both hurting but neither of them wanted to tell their feelings to the other.

As soon as they arrived back they jumped out of the car and saw Ianto walking towards them looking worried. "Hello Sir, there's been a bit of a problem inside. I'm not really sure what's happened, I just got the call and came in. I think you better have a look."

"What is it Ianto?" Gwen questioned him, glancing at Jack for a second, trying to judge whether he was still thinking about that morning.

"Someone's been inside the hub, that's all I really know. They've moved everything around, so they must have been looking for something." The both turned to face Jack, to see what he thought, but he was running off towards the Hub and immediately they followed him.

"God, they've messed everything up." Said Gwen, walking through the cog door, just behind Jack.

"Yeah, whoever came in here must have left pretty quickly", he was scanning the room; now sitting down in front of a computer.

"Unless they wanted our attention", Gwen thought out loud.

"Maybe, lets have a look what's happened here", and as he said so, the CCTV images in and around the hub flashed up onto the screen.

Nothing moved in them for a while, but Gwen noticed something moving around at the back of the room, it gradually got lighter and lighter; bathing everything in the room in a soft golden light.

"What is that, Jack?" she questioned him, but he didn't reply. He was just sitting staring blankly at the screen. "Jack", she tried again and this time he turned to face her; his eyebrows creased and his face immediately showed Gwen that something bad had happened.

"Oh" was his only reply,

"Jack, what happened?" Gwen was starting to worry; she hadn't seen him look this worried about something in a long time and immediately it worried her. She had learnt that whenever something bad happened concerning Jack it also affected her, not only because they worked together but because it made him sad, worrying about her and Ianto and she hated it.

"They are warriors, Gwen. From out of space. The only problem is, we can't see them, not unless they want us too and they've shown themselves on our CCTV.

"Warriors? From where? Why would they come here?" She was worried now, but there were only two of them, how hard could it be to send them back to where they came from.

"They come from far away, in a different time. Guess they must have found the rift and got caught up in it, or decided to pay us a visit. Either way, it would be better if they weren't here. I got involved with one once, a big mistake: I didn't know for a while that they could read thoughts. But what are they doing?" Jack's voice trailed off and Gwen was left to wonder what was going to happen.

"We can just put a trace on it, search for anything unusual coming out from the Hub, they can't be that hard to find." Gwen smiled at Jack, not feeling so worried anymore and although he smiled back at her, she could tell it was forced. "Jack, I'm sorry, about earlier. I think we need to talk about it, again-" but she stopped when she saw Ianto walking into the room.

"Sure, later: Once we've managed to get this whole thing sorted out?" Jack said, a mix of emotions playing across his face, but Gwen couldn't pick out any but she guessed that from the way he had been acting that she must have said something to upset him.

"Anyone for some coffee?" Ianto called out, "And have you worked out what's happened here yet?"

"Yeah, we have. I'll explain it to you, once you've made me my coffee", Jack smiled and walked off, leaving Gwen to gaze after him, before remembering that she had work to do and that she had to stop worrying so much about him.

Back in his office, Jack stared out of his window, trying to look as if he was thinking about something. He was watching Gwen; she had been particularly confusing today, but that was probably because they had crossed any normal boss and employee boundaries that morning and she wasn't sure how to face him. He was wondering why she would want to talk to him again about it; surely she had had her closure earlier, when she told him that it was a mistake. He was feeling a bit annoyed; he couldn't work out why that kiss had meant so much, it was only a kiss after all, but he knew that wasn't really the truth: it may have been just a kiss, but it showed all of their feelings. He couldn't remember the last time he touched someone's lips and felt his heart race, he wasn't sure if it had even happened. When you can live forever, how can one person mean so much to you? That's what he had always thought. But that was before he met Gwen. The first time he saw her, he thought she was pretty, smart but not the sort of person he would fall for. How had he not seen this coming? As Jack watched her, she flipped her hair out of her eyes, and she crinkled her eyes together as she was watching the computer screen, trying to figure something out and Jack realised how much he needed her. He tried for a second to imagine what would happen if he didn't have Gwen in his life, and he realised how empty it would be, how black his life was. Just like it was before he met her, she lit up his life just with her existence and whether she realised it or not, she meant the world to him.

Gwen knew he was watching her, she could see his figure at his office window and why else would he be standing there. He only did it when he wanted to keep track of someone. She was trying to work out what to say to him, whether she should tell him the truth this time, but at the back of her mind, she kept getting reminders of Rhys. They were married, and that was supposed to be forever. Jack meant everything to her, and she loved him, but she always supposed that Jack didn't understand love. Not now, maybe before he was changed, but not now. Rhys loved her, really loved her. And he cared for her. He would do anything for her, but so would Jack. If only she knew, if he had told her how he felt, maybe things would be different…Then she realised she should probably get back to work. She carefully flipped her hair again, just to give him something to think about, and started trying to track the warriors again.
