AN: I went to see Harry Potter and the Deathly Hallows last night: absolutely worth the wait as it was awesome and so true to the book. Who didn't feel sad at the end when the bravest, freest elf was killed? RIP Dobby T_T Point is; I had a bit of writer's block and while thinking about the movie I was inspired for this slightly crack chapter. Also three guesses who inspired the shaking fists bit? ;)

Tosh, Owen, Gwen and Imogene were admiring the item that came through the rift. It seemed to just be some sort of cloak. Jack walked over and picked it up. It felt smooth and slippery to the touch; like it was woven with fabric and water. Jack slung it over his shoulders and struck a pose.

Tosh screamed. "Jack, what happened to your body?"

Jack looked down at what had been his chest but was now empty space. He was a floating head. Jack moved his arms and could feel his body, it just couldn't be seen.

"It's an Invisibility Cloak." Imogene breathed.

"That's too Harry Potter for words," Owen said and there was silence for a few seconds before he jumped at Jack yelling: "Gimme it!"

Jack flung it over his head and laughed. "Time to have some fun."

"We should be afraid. Shouldn't we?" Imogene asked.

"Very." Owen replied.

An Invisibility Cloak, it was very JK Rowling but there was that childish element of being able to pull pranks without getting caught. Jack had five targets and a different trick for each one.

Owen was in the med bay working on an autopsy and helping Imogene with her biology homework at the same time. And they say that men cannot multi-task. Owen reached for the scalpel that he knew he had set down on the metal tray but it was gone. Owen looked up to see it hovering in mid-air.

"Imogene I'm trying to work so quit it." Owen said.

Imogene looked up from the text book she was taking notes from. "Quit what?" she asked before seeing the scalpel.

"That; stop it!" Owen snapped.

"I'm telling you it isn't me doing that." Imogene snapped back.

"How many other telekinetic teenagers are there? Stop it now!" Owen shouted.

"I'm not doing anything!" Imogene yelled and the scalpel fell back onto the tray and a laugh filled the room and footsteps hurried up the stairs. Imogene and Owen looked at each other and yelled across the Hub shaking their fists and yelling one word.

"HARKNESS!"

Tosh was working on upgrading the rift programmes and as she typed the letters and numbers on her programme kept disappearing and changing. Tosh shook her head and bent her head down keeping her gaze on the keyboard as she typed but it was still happening. What was up with this stupid thing? Tosh decided to do a test. Her hands flew over the keyboard like Usian Bolt on Red Bull and caffeine pills and smiled. The erasing was happening slower than her typing. Tosh lunged the air around her and her grip locked on a finger before it was pulled from her grasp. Tosh glared at the sound of running footsteps and shook her fist yelling one word:

"HARKNESS!"

Gwen was sitting at her desk trying to work on reports but was really daydreaming about herself and Jack. He wasn't really going to marry the tea-Boy right? He was obviously deluded or hoodwinked by the kid into thinking he loves him. And his bratty little sister probably was using some mind control over Jack. But Gwen wasn't stupid. She knew that she and Jack belonged together and if they didn't. Well then she'd just settle for Owen. Owen had been so heartbroken when she called off their affair. Gwen knew that she just had to say the word and he'd come running back to her. Gwen was lost in her own self-centred thoughts that she jumped about ten feet in the air when a liquid was dumped all over her. She could hear a deep chuckle and swore under her breath. When he was with her, he would have to act more mature. Gwen shook her fist and yelled one word:

"HARKNESS!"

The four of them grouped down in the cells. They weren't sure whether or not they were safe but they were all leaning against a wall to be sure.

"So he got us with the scalpel, Tosh with her computer and Gwen with the coffee. Who has he missed out? Or in other words, who's next?" Owen asked.

"Where's Ianto? Has he been in all day?" Tosh asked.

"He's at home sick, apparently even the great Ianto Jones is no match for Man Flu." Imogene smiled at Gwen and Tosh who rolled their eyes in a show of female unity. Why was it that every time a man got the flu he was convinced that it was horrible and that he was dying of pneumonia or the plague?

"Hang on, you said Ianto was sick and home alone, that means that he's defenceless." Tosh said suddenly.

"He doesn't know about the cloak." Gwen added.

"Thank you Madam Obvious. We'll have to ring him but I've no credit on my phone." Imogene said.

"Take mine." Owen said and passed her his mobile. Imogene flicked through the contacts until she found Ianto's name and pressed the call button and put it on loudspeaker.

The phone was answered by a cough and a rasping noise that sounded like a hello.

"Yan, it's Gen. we need to warn you about something." Imogene said.

"What?" Ianto asked.

"Jack has an Invisibility Cloak." Owen said.

"I know." Ianto replied and he sounded sort of breathless.

"You know? How?" Gwen asked.

There was a pause and a moaning sound before Ianto answered them. "Lots of things you can do with an Invisibility Cloak."

The phone went dead.

The four of them looked at each other and said only one word while shaking their fists at the celing.

"HARKNESS!"
