Gwen was running, her heart pounding so fast she could feel it in her throat. Her hand was bleeding, a deep cut trailing from the bottom of her thumb halfway up her index finger. However, she had other things on her mind. She needed to catch him. The alien creature had sharp claws up to 6 centimetres long, a dark green face with scarlet eyes and purple bumps all over it.

'Jack, I'm losing it', Gwen huffed, almost out of breath.

'Where are you?' Jack asked her, talking through the headsets that they all had.

'Just coming round the corner of the huge set of garages.' Gwen began slowing down. The thing was almost out of sight.

'I've got it', Owen said. They then heard a noise that could only be explained as Owen diving on the creature and hitting the floor.

'We're coming', Jack replied.

Gwen was the first one to reach Owen. He was struggling to hold it down. 'Those claws are big', Gwen said, admiring the huge, knife-like things on the end of its hand. It then threw Owen off of itself, and he hurtled through the air, hitting the floor hard. The thing then jumped up, taking a swipe at Gwen and splitting the leather of her jacket. She was left with another deep gash, this time on her upper arm. At that point Jack and Tosh appeared. 'He's getting away again' Jack shouted, running at the alien creature and tackling it to the floor.

'Owen, are you okay?' Gwen asked, remembering that he had hit the ground quite hard.

'If I get a bloody bruise..' he replied, getting up slowly.

'Owen, I need the needle!', Jack shouted, struggling to hold the thing down. Owen handed him the needle, and Jack injected it into the creature. The thrashing decreased slowly, and then it lay there, unconscious underneath Jack.

'There we go. Owen will you give me a hand?' he asked, lifting the creature's legs up. Ianto then pulled up in the car.

'He's not a looker, is he?' Ianto commented as he helped Jack lift the creature into the boot of the car.

'I've seen better', Jack replied, pushing the thing's legs into the boot securely. Gwen and Owen had already gotten into the car. Ianto and Jack were chatting as the got into the front of the car when Owen interrupted them, sounding concerned.

'Uhh.. Jack?'

'What?'

'It's Gwen..' Owen replied. Jack turned round and saw that Gwen was sat in the back, extremely pale, covered in purple spots.
