Tom opened his eyes to find a sword pressed to his throat."You will not move, Loki Laufeyson" Came a voice from beside him. Heimdall.

Tom glanced to see Chris staring at the scene with awe, probably at his surroundings, and a hint of amusement. "I'm glad you're finding this funny" He said only to have the sword pressed harder against his throat. Ok maybe that had been a bad idea.

"Are you well Chris of Hemsworth" On hearing his name like that Chris grinned. Tom rolled his eyes and fixed him with a glare.

"Yes um.. Heimdall." The grin stayed fixed on his face. He noticed the glare Tom was giving him. He cleared his throat, "Um could you let Tom go?" He suggested starting to chuckle. Ok now Tom was getting irritated.

"This is Loki, you must understand that" This admittedly was one part of the plan they hadn't really thought through. How to prove to Heimdall who he was.

Chris finally sobered up, "Look mate, he really is we were just trying to get your attention. You see we heard about events here at Asgard and wanted to do something about it."

"You expect me to believe this?"

"Hey would I side with some nutter who had stabbed me in the past?"

Hemidall hesitated, clearly unsure.

"I promise that i'm not Loki." Said Tom, attempting to back away from the sword again. This time Hemidall allowed it and lowered his arm.

"This could be my biggest mistake" He muttered.

"I promise you it isn't."

"You had best explain or my sword will find your throat."

"Right well..." Tom started. He explained about the script and his opinion of what had happened. How he had tried to 'change the writers mind' to which heimdall had responded, "Idiot mortal". And then, "I need your help to save Loki. He can't just die after turning good, it's wrong"

"What proof have you that he is good"

"He sacrificed himself for Thor."

"This is true. It is possible his heart had changed."

"Will you help me?"

"I do not see what I can do"

"Well I read that you do, on rare occasions, empower people will time tra.."

"It is forbidden"
"Why?"

"Loki"

"Really. How did he manage to get time travel banned"

"A series of events involving a horse"

"Would that be the one involving an event involving an eight legged horse?"
"Yes"

Chris laughed. Tom glared at him."I'm sorry its just, I didn't think that was actually true.." He burst out laughing again.

Tom turned back to Heimdall, "Any chance it can be unbanned"

"I would be willing to help you but.."
"Theres always a but"

"The source of power that would allow you to travel is locked away in a vault and the only one with access to it is..."

"Odin" supplied Tom

"No"

"No?" said both Chris and Tom in unison surprised.

"No, it is Thor."

"Well it's a good thing we have our very own Thor right here then isn't it" Tom turned to Chris who raised his hands.

"No. That is not a good idea."

"Come on all you have to do is act in character!"

"Then why don't you shape shift"

"The vault is guarded against this"

"Of course it is."

Tom gave him the puppy dog eyes. "Seriously no!"

About half an hour later Chris found himself facing the vault doors. Sigyn by his side. Well when I said sigyn I meant..

"Tom, what do I do"

"I dunno, bark orders at the guards or something. I can't go any further or they'll realise!"

Chris huffed and marched forward, Thor was present.

"I demand that you remove the enchantments so I may enter"

"I am not sure it is wise"

"Do it!" he bellowed

The doors were opened and enchantments removed. A few minutes later Chris emerged carrying the small hourglass Hemidall had described to them. He joined Tom and they met with Heimdall in Loki's room. No one ever went in there any more.

"I always wondered what it would look like" murmured Tom looking around. Spell books lay scattered across the room. An old battered wooden sword shoved almost out of sight and a picture, or was it a hologram of Loki and Thor as children sat on a cabinet. That made up his mind, Loki could not be all bad.

Heimdall gestured for them to join him around a table. Chris placed the hour glass upon the table.

"This will allow only one of you to travel back you must decide who."

"I vote Tom"

"What if I vote you?"

"Come on if he sees me he's just gonna think Thor and try and kill me or something"

"And if he sees me he's gonna think, 'hey you're the bloke that got me imprisoned' and try and kill me"

"May I make a suggestion. I believe it would be more sensible to send Tom"

Chris grinned. Tom punched his arm, "Ow!"

"Fine, I suppose your right. What do I have to do."

"You must eat a grain of sand."

"Eat?"

"This will allow you to move with the hourglass as it travels in time. When the sand falls through and its top half is empty it will move back forward in time, whether you are with it or not."

"So if I don't keep hold of the hourglass then I have to live through to present day."

"Yes"

"How long has it been since Loki died."

"Five midguardian months"

"Not to bad. How long will I have"

"This is unknown"

"What!"

"It changes with each use. Last time Loki stayed for a week."

"Hey at least you won't be working in hours mate" Chris offered in the way of consolation.

"We are short of time. I do not expect your presence here to stay unknown"

"Alright give me some sand"

Heimdall removed a grain (with great difficulty) and handed it to Tom

"Good luck mate"

As Tom swallowed the sand Heimdall turned the hourglass. He faded from view.

"How long will he be"

"I expect the hourglass to return within a minute"

The doors where thrown open and a pair of guards walked in, "Odin allfather requests both Heimdall and Thor in his presence immediately"

"So much for staying unnoticed" muttered Chris as they were marched to the throne room. Moments later the hourglass re-appeared on the table, without Tom.
