Rina was about to start her explanation when Tosh's computer beeped again, this time in a steadily increasing pattern.

"It worked!" Tosh sounded surprised as she hurriedly tapped keys, checking various readings against her main monitor. "I reconfigured the program I setup, using a type three algorithm to calibrate…" she paused, seeing the blank looks on everyone's faces.

"Basically, I changed the program so that it would alert us to the very beginning of the power surge. This way, maybe we can catch whoever's doing this before they get away!" The looks turned to comprehension, and Jack began barking out orders.

"Ianto, jeep by the front entrance, Gwen, get two or three of those reconfigured prison stone thingys you used on that sex-addicted alien, Tosh, get together everything you need to track these people, and something to take readings. Owen, weaponry. Now, people!" he whirled on his heel, greatcoat flying. For the first time he looked Rina straight in the eyes and spoke to her.

"Coming?" she grinned, her eyes lighting up at the prospect of some adventure. Jack nodded, hiding a little smile at the thought of having Rina with him on a hunt again.

Gwen returned from the harmless artefacts room near the cells just as Tosh finished downloading everything she needed onto a hyped up PDA. Owen, fighting the new and improved (and ridiculously high) security on the weaponry case finally got it open as Jack returned from collecting his gun from his desk. He tossed a gun over to Tosh, ignoring her look of horror at his recklessness as she caught it. Gwen next, who shot him a look full of laughter as she tucked the gun into her back pocket.

The look sent his stomach reeling. Maybe I should have persuaded her to carry on with our…whatever it was, he mused as he picked a weapon for himself. Nope, she made her choice. Rhys is all she needs, we're both sure of that now. He sighed, then pulled one more gun and ran out of the door, following the others as they made their way up the stairs to the jeep. Once outside, he nearly ran into Tosh and Ianto, who'd stopped in the doorway. He sidestepped at the last minute as they ran over the equipment one last time, for safety.

He looked for Rina, finding her off to one side, breathing deeply. He chuckled to himself. Obviously the air in the Hub had been a bit too much for her. Well, some people couldn't take the peculiar mix of gunpowder, various chemicals from his morgue and the unusual smell of pterodactyl. He moved up beside her and held the gun out.

"Here. In case things get a little too much for you. Just don't use it unless you really have to." Her response was not what he expected.

"I don't need a gun, Owen." Not 'I don't want a gun' but 'I don't need a gun.

"Rina, trust me, some of the situations we get into can only be rectified by using a large calibre weapon. Such as this one." He fought to keep the irritation out of his voice, as he really didn't have the patience to deal with a jumped up little girl who thought that just because she'd managed to get into Torchwood she was so good she didn't need a gun.

"Hey! Guys, what's the hold up?" Jack yelled from his position by the jeeps driver side door.

"Your friend here thinks she can survive with out a gun." Owen yelled back, fixing his eyes on Rina to let her know how stupid he thought this idea was.

"She can!! Now get in the damn car Owen!" getting into the jeep, Jack started the engine as Owen looked at Rina disbelievingly, then ran and jumped into the passenger side of the all-black monster that carried them around Cardiff.

Rina smiled, amused by Owen's reaction. She breathed deeply again, and then focused her mind onto shifting.

Let's see if Owen's as sceptical when I beat the team there!

Jack walked into the alleyway, flanked by Gwen and Owen. Tosh and Ianto were by the jeep, frantically trying to get a solid fix on the intermittent power source.

"Doesn't look like there's anything here." Owen pulled a face, clearly not relishing the thought of another wild goose chase. They always ended with Jack in a very bad mood. Thankfully, Tosh came racing up to them, waving her little PDA.

"I've got a solid fix! It's coming from the building next to us," She said, already scanning the wall with another device pulled from her bag. Jack looked round and saw a wrought iron staircase leading up to the roof.

"Gwen, get up those stairs, see if there's another way into the building. Owen, with me around the front." They split up, none of them noticing the dark shadow that passed over the alley.

Once on the roof, Gwen realised that Tosh had been slightly off with her location. The power source wasn't in the building, it was on it. Gwen had just walked straight into the things that were killing people all over Cardiff, and she knew with one look that her gun wasn't going to be much use.

They were human, that much was obvious, but that was where any similarities with Gwen herself pretty much ended. The right amount of eyes, legs, arms and heads – by Gwen's standards, anyway. She suspected Jack had other ideas. Now that her eyes were adjusting to the odd half-light up on the roof, she could see shapes moving behind the aliens, rather like wings. Even after meeting the Mara Gwen had trouble believing anything that had wings wasn't sweet and kind and wore flowers petals. Although the teeth the things were currently bearing at her were doing a lot to alter that belief…….

"Jack? You need to get up here…" Gwen lowered her hand from her headset, looking on in disbelief as another shape flew down from the sky to join the others. The new shape wasn't there for tea and cakes though, as it proceeded to dispatch three of the oddly humanoid beings, and wounded the fourth, obviously badly from the amount of garish blue liquid flowing from the area which would normally be the torso.

Gwen stumbled back as the new shape looked at her, then whipped round as a noise behind her made her jump. Looking back, her rescuer had vanished. Now that was definitely weird. Those things seemed to hunt in packs, and yet one of their own kind had attacked it solo. Gwen filed this piece of information away for later as she advanced on the curled up shape near the edge of the roof. After thoroughly checking all areas to make sure there were no more of the freaky things around, she bent down and felt for a pulse on the – hopefully – human lying on the floor. Nothing.

"Gwen! Are you ok?" Jack and Owen were finally climbing onto the roof. None of them noticed a thickening of the shadows around the single door down into the building. A moment later Rina stepped out, walking over to where the others were crouched over the dead guy. Owen pulled various instruments out of the medic-pack he carried everywhere possible, and proceeded to take readings of everything from the temperature of the air to a swab of some water pooled nearby.

"What happened?" Owen and Gwen jumped with fright as Rina spoke, and Jack only just saved his dignity by managing not to let out a little squeak. Well, she was standing right by him. Damn, I'm loosing my touch! How'd she get so close? Rina was looking at them expectantly; apparently not aware of the effect her sudden appearance had had on them.

"Well, looks like Gwen interrupted before they could really get down to business, seeing as there's still a body." While Owen did something fancy with the alien version of a body bag, Gwen watched Rina walking around the rooftop. She was sure that the new girl hadn't come up the stairs, and there was no other way onto the roof. Unless………. Gwen's mind refused to go there for a minute, and then she made herself think it through.

Rina had managed to find Torchwood, and get inside. Jack seemed to know her, and she'd gotten to the scene without mentioning any transport of her own. She'd also gotten onto the roof without anyone hearing or seeing her. Gwen decided that she really needed to talk to Jack about this girl.
