Sliding through the heavy metal door, Danny flinched at the sudden brightness of the room as he came back to tangibility. The chamber where he had been kept prisoner had been so dark that he had to spend a minute blinking the stars out of his eyes.

Shaking his head lightly to stare at the grey-slate wall in front of him. Twisting, he found himself in a narrow winding corridor. No other doors in sight. Shrugging, Danny headed right, beginning his trek down the seemingly endless path, with no sense of direction or any idea of where he was going.

Thor's long pace made it difficult for Jane to match. Her shorter legs scurried across the tiled floor as she struggled to keep herself upright. She was beginning to get tired – she was a scientist, for goodness' sake! Physical application was not her forte.

Glancing up quickly at her otherworldly boyfriend, Jane took note of the deep frown marring his (in her opinion; pretty) face – his eyes focused on what was in front of him. Jane doubted that Thor had even noticed her beside him since 'Danny' was announced missing.

Panting, Jane found herself rapidly falling behind as Steve, Fury and his two SHIELD lackeys overtook her to speed off down the corridor with Thor. Fury was rapidly speaking into an earpiece as he ran, calling for backup.

Slowing to a stop, Jane rested her hands on her knees as she gulped down air for her burning lungs. Leaning against a wall, she forced herself to stay upright. Jane had no idea how any of them could do it, the Helicarrier was huge and the cell was of the far side – as far away as possible from the main control room in case of an escape like this.

Feeling her heart begin to beat at a much less radical pace, Jane stayed stationed against the wall. The last thing she wanted was to get lost in the giant aircraft. It was better to wait for the others to return.

Quiet murmurings echoed though the corridor, bouncing off the walls in muffled tones. Tilting her head, Jane recognised the voices to be Tony Stark's and Bruce Banner's, and snuck her way across the tiles towards them. Reaching a bend in the corridor, she strained her ears to catch glimpses of the conversation, keeping out of sight.

The pair must have been walking at a languid pace, seeming in no rush to fight or detain the Draugur – or 'Danny', whatever its name was.

Tony's voice cut through her musings, "Hey, you call it abuse, I call it life experience!" his voice was oddly jovial for such a dire time.

"It doesn't matter, Stark. He's still a kid. You can't treat him like he's one of your lackeys. He didn't choose for this to happen, you pushed him into it," Banner's voice was grave in response.

Tony sighed dramatically, "Alright, alright. I'll lay off Dan-Dan then. Happy?"

Dan-Dan? Who in the world was Dan-Dan? Jane frowned confusedly.

"No, not quite," Doctor Banner said coldly, "Stop hinting at who he is. It's not a game, it's his identity. Not everyone wants to announce their secrets to the world. Don't mess up his life just because you think it's funny."

Tony didn't respond.

Jane was quickly becoming more and more confused. Were they talking about the Draugur, Danny? Or someone else? But why would a ghost-zombie-demon-thing need a secret identity? It was already dead, wasn't it?

Loud footsteps were quickly approaching Jane's hiding spot. Not wanting to be caught eavesdropping, Jane spoke up, attempting to keep her voice even as she shoved herself off the wall, "Tony? Doctor Banner? Are you there?"

The footsteps halted. A heavy silence flooded the narrow hallway, until Tony spoke up, a fake cheeriness in his tone, "Jane!" he cried, as the two men rounded the corner, "What are you doing dawdling? I would have thought you'd be up there with you living blond Ken-doll!"

Jane coughed uncomfortably, "They ran off ahead," She said, before sliding them a glance, "What about you two? Why aren't you with them?" Her eyes swivelled to Bruce Banner.

Said doctor stiffened – his back ram-rod straight and eyes alert, yet he stayed silent.

Tony shrugged, "Double-checking the recordings, of course. We wanted to see if we could catch any footage of Danny escaping. See what ghoulish things he could be up to."

Jane saw Doctor Banner grimace slightly. Her eyes narrowed in suspicion.

A loud clap interrupted her thoughts. Tony's false smile was creasing his face, "Why don't you head back to the meeting room and wait for us there, Jane? We won't be long! Ta-ta, mon cheri!" Tony tugged Doctor Banner by the elbow and began to briskly walk down the corridor away from Jane.

"Wait!" She called out, scowling as they rounded a corner. There was no point trying to catch up to them – they could outrun her by a mile. Pushing herself off the wall, Jane reluctantly made her way back to the hub of the Helicarrier, contemplating as she walked. Maybe she should take a look at those tapes.

Sliding through another wall, Danny held his breath, still cloaked in invisibility with his eyes clenched shut as another group of agitated SHIELD agents bustled past, screaming orders of incarcerating the Draugur.

Danny was seriously going to punch Tony in the face the next time he saw him.

Hearing the agents make their way down the corridor on the other side of the wall, Danny apprehensively turned around, peeking his eyes open, and sighed in relief. He was in a changing room. Black steel lockers stood in neat rows along with low benches placed in each aisle. There wasn't a person in sight.

Making a quick scan of the shower room next door, Danny concluded that it was empty and became visible. Planting his feet on the ground, the half-ghost made his way down the closest aisle – curiously looking at the lockers; giving in to his fascination, Danny stuffed his head into the closest one, yanking it out just as quickly, gagging on the air. Even Dash Baxter's locker smelt better. He should know, he'd been stuffed inside it enough times when he was younger.

Moving on to another locker, Danny slid a hand inside, opting to force the lock open from the inside. A soft metallic clank was heard, with a grin he grabbing the handle, and, listening sharply in case anyone else entered the room, Danny yanked the door open.

A cheeky grin spread across his face as he pulled out the contents inside.

Nick Fury was past angry. He was, well… furious. His only link to capturing Loki had escaped a containment cell built to harbour otherworldly gods, and he had no idea how the darn thing did it. The entirety of the chamber was frozen solid, and Fury's agents weren't even able to release the glass from its seal to check whether or not the Draugur was still inside.

Massaging his forehead, he barked out a command, "I want all available officers to stop working on the cell and do a full spread of the Helicarrier! The rest of you, keep searching the rest of the planet for that god-damn god!"

Affirmations were heard throughout the room as agents quickly dispersed in teams. Thor walked up to him as the last SHIELD operative left the room.

"The Draugur is toying with us."

"Toying? Do you really think so? Danny doesn't really seem that bad – except for the whole Asgard thing, I mean,," Steve said as he stood next to the pair.

Thor grunted distastefully, "Draugar do not simply run away from battle, puny mortal. They are vengeful creatures that wreak destruction at any chance for the sheer thrill of it. There is nothing more feared in the nine realms than the Draugur. They were believed to have been locked away with Hel herself after the invasions in the early centuries on Midgard."

"What invasions?" Steve's eyes began to flit nervously across the room. Nick Fury stood poignant, but his hand hovered over his holster.

"Many died during that time. They were dark ages for the humans, us gods found the Draugar difficult to control. When Lady Hel was cast out of Asgard we forced the Draugar out of Midgard as well. Our battle has forged through many a millennia," Thor clenched his jaw tightly, "There is no love lost between our kinds. I believed that my father had exiled them forever. Obviously they have found a way out."

Fury cleared his throat, "That is all very good, Thor. But how do we destroy them?"

Thor looked agitatedly at the frozen chamber, "You cannot destroy a Draugur. You can only banish them," Turning and looking into Fury's single eye, Thor said, "Let me gather my people – we may be able to find and capture both Loki and the Draugur before the Earth finds itself at any more harm."

Fury almost scoffed, "Sorry to say no, but it has come to my attention that your kind are incapable of taking care of even your own enemies – let alone the Earth's. First with Loki, now with these Draugar. SHIELD is going to be taking control of the situation, and you might be surprised how far technology had developed, Thor. Draugar may no longer be as immortal as they once were when we get through with them."

Turning on his heel, Fury ignored the dark looks from Tony Stark and Bruce Banner standing in the doorway, and exited the room, the ecto-gun in his holster pulsing.

Tugging the zip closed on the black suit, Danny gave a sigh of relief. Who knew putting a one-piece on could be so difficult? He had to hand it to his parents, who practically lived in their own; he wouldn't know what he would do if he had to shove himself into a tight uniform like this every day. It didn't help that it was two sizes too small, but sadly it was the largest one he could find.

Glancing in the mirror Danny looked over his appearance. The SHIELD uniform was more than snug on him and he was pleased to find that the large boots covered his exposed calves – his forearms, sadly, were not so lucky; he'd shoved the material past his elbow where it now sat pinching painfully at the inside of his crease. His black hair hung shaggily in his blue eyes as he brushed it back out of the way in an attempt to look older: he now resembled his dad. Giving a sharp yelp of fear, Danny shook his head roughly, letting the locks fall back into their haphazard style.

Running his hands across his face with a groan, Danny forced himself to stare at the copy in the reflection. Blue eyes stared wearily back at him Danny whispered from between his fingers, "Okay, you can do this, Fenton. Just keep calm and act like you know what you're doing. Just get in, find out what they're up to, kill Tony, get the blueprints and get out. Easy."

Taking a deep breath, Danny grabbed the phone he had snatched from a locker and nervously walked out of the room, thankful that at least his uniform wasn't orange.
