Chapter 6.

Jack and Gwen took the SUV to get to the park. Jack was driving even more erratically than normal as his thoughts kept drifting to the conversation that he was going to have to have with Ianto later that day.

'Jack, please watch the road!' Gwen yelled at him, as he drove through a red light. 'What is going on, your driving is worse than normal.'

'Sorry, I have a lot on my mind.'

'Anything I can help with?' Gwen asked.

'No it's something I have to do.' Jack had no idea how he was going to do it though, the whole Canary Wharf issue and what happened after was a sensitive one. He stopped the car in the same place as he had the other day, and they walked over to where the body had been discovered.

'What exactly are we looking for, we never found any trace of the thing the first time. Plus we need a name for it, I'm fed up of not knowing what to call it'. Gwen said.

'I wish I had a name, because then we would know what we are dealing with. Lets widen the search area and head towards the woods to see if that gives us anything.'

Molly and Jamie had taken his car back to the where they had seen the alien creatures at the bar by the Quay.

'We know that the aliens disappeared over there when Jack and Ianto shot at them, and that there was nothing of any significance left behind, but where did you go when we first left the bar, maybe the one that followed you left something behind.' Molly said.

'I headed that way,' said Jamie pointing in the direction that he had gone, 'I went down the side street to try and lead it away from the bar.'

'Ok, so lets look that way.' Molly started to walk in the direction he had pointed.

'So,' said Jamie, 'How did you get involved in all this?'

'Errmm..' Molly wasn't sure how to explain it.

'Don't tell me its another long story.' Jamie answered for her.

'You could say that, but it is connected to the other long story I mentioned.'

'You don't give much away do you?'

'Well to be fair I've known you all of two days.'

'True, but it would be nice to get to know you better.'

'What about the others?' Molly asked.

'I suppose I'd like to get to know them better too.' Jamie said. This was true, but there was something about Molly that intrigued him, and out of all of them she was the one he wanted to get to know most.

''It works both ways though, you have to tell me about you in return.' Molly couldn't quite believe what she was saying, was she flirting? She wasn't sure, but that definitely had not been her intention. She had not had the best of luck with men in the past and had vowed to keep her distance. Then again she had also vowed never to have anything to do with aliens and that hadn't exactly worked out.

They had reached the side street and Molly pulled out a hand held device looking for residual Rift energy, but found none. 'I swear if I hadn't seen those damn things for myself I'd think people were making them up, there's no trace of them.' She was just about to call Jack to see if he was having any luck, when Ianto came on over the comms.

'You need to get over to the docks right now. One of the creatures has been spotted there.'

'On our way' Molly said, as she and Jamie ran back towards the car.

'Us too' she heard Jack say over the comms.

They arrived at the docks at the same time. They went towards the sounds of screams and a noise that sounded like a wild animal. They turned the corner and saw one of the creatures attacking a dock worker. Molly and Gwen both turned away for a moment to compose themselves, it was not a pretty sight.

'Ok, we need to surround it, and then try to take it down before it goes for one of us.' Jack said. I'll take the front, so if it does go for someone it will go for me.'

The other three nodded, and slowly started to move around. The four of them stood circled around the creature which suddenly realised that it was in trouble. It stood up and let out a loud growling sound. 'Fire!! yelled Jack. All four of them fired at the same time, Jamie discovering that he didn't have too bad an aim considering he hadn't long had a gun. The bullets didn't seem to make impact on the creature initially, it was almost like they bounced off it. Jacks plan didn't quite work as it turned and went for Gwen. Just as it was about to get to her, it fell. A bullet had hit it at the base of it's head. They gathered around it.

'One down.' Jack said.

'Yeah and three to go.' said Molly, as she helped Gwen up.

'This will give us something to go on though, Dr West, I believe an autopsy is in order.'

'Great, first alien autopsy. God there's something I'd thought I'd never say'.

'Let's get it back to the Hub.' Jack and Gwen wrapped the creature up and put it in the back of the SUV. Jamie rang one of his contacts from the station where he had worked and arranged for the body of the dock worker to be transported. There had only been one witness, the person who had phoned the attack in, and Molly took care of him with a drink that had some retcon in it.

Half an hour later and they were all back in the Hub with the alien lying on the autopsy table.

'It's quite amazing really' said Jamie as he looked the strange alien creature laid out on the table. The others all looking on from above.

'Amazing is not the word I would have used.' said Molly. 'I think terrifying covers it better.'

'Sure, when your being chased by one. Cut me some slack it's not like I do this everyday. I can see why bullets don't have much of an impact, it's skin is really tough, almost like an armour. Apart from the one weak spot at the back of it's head.'

'At least we know how to kill them, the only problem we have now is finding the other three.' said Gwen.

'Ok' said Jack. 'Jamie, keeping on looking and see what you can find, Molly and Gwen analyse the samples that he gives you. Ianto, you're coming with me.'

Ianto looked at him puzzled. 'Where are we going?'

'It looks like being a late one, so we are going to get some food supplies.'

Ianto was still a bit confused by this, he quite often went out and got food for the others when they were going to be working late, but Jack rarely went with him. He was starting to suspect there was something more to it.

'Ok I'll get my jacket.' Ianto walked over to his desk to retrieve his jacket.

As Jack turned to go, Molly grabbed his arm and whispered so the others wouldn't hear. 'Since when do you go out for supplies. There's more to it right?'

'Yeah, I know I have to talk to him and I need to do it now, before I talk myself out of it.'

'Good luck.' Molly said.

Jack and Ianto walked out through the cog door and once they were outside, Jack stopped and turned to Ianto.

'I had an ulterior motive for coming with you.'

Ianto looked at him, and raised his eyebrows. 'Ok, what is it?'

'We need to talk.' said Jack.
