A/N: Following the events from everything but AOU, this story follows the cute misadventures of a de-aged Thor. Hoping to make it a multi-chapter fic, but we'll see where it goes. :)

Thor's POV:

The patience of a 5-year-old was easily compared to that of dog with no strict schedule. Not that tiny Thor noticed. The small being had gotten bored of simply dangling his legs over the side of the bed at the S.H.I.E.L.D. offices, so as soon as the short redhead had turned to talk to the doctor, he bolted.

It wasn't that there was a lack of security, or distrust of the adults he had been surrounded by, he was just bored, and in a desperate need of some playtime with his new baby brother, Loki. An odd thought, he reminded himself, to no longer be the center of attention. But the small nine- month- old had proven entertaining for his abundant curiosity, and would often even reach to him. That was his favorite part, when Loki would stretch his chubby fingers for him, sometimes in preference over their mother. The thought made him smile as he sucked on his thumb and passed another bleak hallway that seemed to lead nowhere.

They seemed to stretch endlessly, he noted, with no clear purpose. Even the halls of Asgard, numerous as they were, often bustled with life, be it a guard, or very persistent nanny; someone was always present.

He paused in one hallway, just short of a right turn, to again observe his surroundings. His thumb, now coated in saliva, echoed a sucking noise throughout the empty passageway as his nervousness gave way to more thumb sucking.

He looked to where he had come from, half expecting to see his nanny chasing him, and wandering why these strange people were not doing the same. Perhaps customs were different here, and children were allowed to roam more freely? The thought motivated him, giving him the courage to turn the right corner, only to be rewarded with a knock to his head as he ran into something hard.

Tears sprung to his eyes, making him place his sore thumb back into his mouth. He crawled back a little, and then pushed himself up to look down the hallway again. He had run into a small table, it would seem. His crying stopped. Thor looked away from the table, slightly embarrassed as a group of adults came down, all talking to themselves. He wasn't afraid though, there were so many strangers here, and all of them had been kind, if not concerned.

The thought truck him, making him pause.

Concern; they had been concerned.

His tiny face scrunched up as he considered this. The redhead had told him that his parents had sent him to spend some time here so that they could accomplish some things, so why were they concerned? He hadn't remembered doing anything offensive or wrong… Perhaps they didn't approve of crying?

He sniffled, but tried hiding his red eyes from the new adults as one of the approached him. The adult had a large smiled plastered on his face, but his actions were those of a wary person. He was taller, much taller than the other men Thor had met so far. His clothing was simple, and his hair was blonde like his. The man came closer, the other two whom he had been talking to pausing just behind him. The guy didn't address them though, instead, he got down on one knee in front of Thor, and offered out his hand.

"I'm Steve, what's your name?"

Thor tilted his head, and removed his hand form his mouth so that he could shake Steve's hand.

"Thor," he replied, returning the broad smile in full.

The other man faltered, smile wavering. Thor wondered if it was because he was missing one of his front teeth. The customs here still were not plain (Especially the clothing, he thought, small hand tugging at his t-shirt), but this man had appeared nice.

"You look a little too small to be wandering around by yourself," the man said. He had apparently recovered, and was now rising to an intimidating height. The smile was back now, though.

"Oh," was all Thor could think to respond. Perhaps it wasn't custom to let children wander. He blushed at his foolishness.

A shorter man, dressed in purple, approached. He too donned a bright smile. A fake smile, Thor's mind supplied, a very fake smile. This man was also blonde, but it was a dirtier, darker blonde. His eyes were greyer as opposed to the Steve's baby blue ones. It was an odd, yet complementing contrast, which led Thor to think that maybe they were related?

He shook his head and stuck his thumb back in his mouth. Loki had black hair and green eyes, and they were related. These men might not even be well acquainted.

He shook his head again. These men had been conversing in the hallway; they had to at least have known each other for some period of time.

He squinted as he caught the tail- end of a conversation that he hadn't been aware the adults were having.

"No," Steve said, whispering just high enough for the other man, and apparently Thor, to hear, "I don't think he remembers." He stopped to look around the hallway before turning back to the shorter man, "Where's Natasha? I thought she said she'd be handling him?"

The man shrugged, another, slightly taller man, with dark curls and a warm, less fake smile, coming up behind him to glance at Thor. The short man shifted so that the curly haired man could offer a small smile, and wave to Thor, one Thor returned with his slobbery hand.

Steve, now crouching back down, smiled again, but this time grabbed Thor's arm. "Come on buddy," he said, "let's take you back to Natasha, she's probably worried sick."

Thor blushed again, embarrassed that once again he had broken some ritual he wasn't aware existed. He followed Steve though, as the man led him along back the way he had come, the two other men following close behind, chatting; this time, out of range of his small ears. Again, they passed no one, which was odd to Thor. Why have so much room, if not to use it?

They passed the demon table that had bruised his thumb, taking turns into the empty halls that felt the need to be filled. He frowned, scratching at his arm, glancing at Steve, then looking ahead again; bored with the white walls. This whole trip had proven boring.

They ended up back at the medical bay where Natasha was talking hurriedly into something. She stopped when she saw them approach. Thor smiled at her, desperate to appease her worry, but her stoic demeanor didn't waver. She had her eyes on the shortest man though, who was now trying to blend into the wall.

As Steve ushered him inside the small room again, Thor over- heard the woman shouting at the short man in a language he had never heard before. He tried wriggling form Steve's grasp, curious to see what they were doing, but Steve pulled him up on his shoulders, making the escape impossible. Dejected, he sat with his arms crossed, pouting about his loss. It wasn't fair sometimes, being so tiny.

He perked up though when he saw the doctor again. The kind women offered him a kind, exasperated smile, which made him want to hug and kiss her, like he did when his mother was worried, but relieved to see him. Worried about what I might have gotten into, he thought to himself. The idea made him giggle.

The doctor motioned Steve back to the uncomfortable bed, the tall man obediently complying. With thick arms, the man reached upwards with large hands, extracting Thor from his shoulders, who giggled as the fingers made contact with his stomach. This made Steve chuckle as he placed the small child on the bed.

Again, Thor found himself impatiently dangling his legs, still unsure as to why he had to see a healer, but he hoped it wasn't anything serious nonetheless. He'd hate to have to worry his hosts so. He especially hated the amount of concern that seemed to follow him everywhere. Didn't they know that he'd be home soon with his mother, and that there was nothing to worry about?

Of course, that was unless he was dying from a human illness.

The new thought made him shudder, just as the doctor listened to his heart again with that odd instrument of hers. He kept his eyes on her. Never once looking away, shoving thoughts of a slow, painful death to the back burner of his mind. The doctor was intriguing, by whom she was, and what she wore, and what she used more intriguing yet. So he made sure to have her in the line of sight as much as humanly possible.

She walked away to write something down, Steve taking the spot closest to Thor where she had been standing moments before. The child looked up at him with awe, but averted his gaze before they made eye contact.

Instead, he stared at his small hands, wishing that Loki were there to hold them. Loki had been practicing a lot lately at walking, much to their mother's chagrin, and Thor had been his primary tool. Now, sitting in the room with only adults, adults who wanted to check his breathing and just about everything else, Thor wished more than anything to help Loki walk. Or perhaps play a simple game, like a hide and seek.

He smiled at the last thought, suddenly very excited for this whole trip to be over, if only to spend more time with his brother and mother. He stuck his thumb back into his mouth, but was shocked when Steve pulled it out. He looked up at him incredulously; wandering again, if this was inappropriate behavior. If so, why didn't everyone enforce such rules?

The doctor came over, forcing him to shift his gaze so that he could stare up at her, thumb completely forgotten. She had green eyes like Loki, but blonde hair like him. He wandered vaguely what her parents might have looked like.

"Well, everything is ship- shape," she said.

Steve nodded, looking relieved. The doctor smiled down at Thor. Thor smiled back, thumb twitching as he tried not to stick it back into his mouth, the absence becoming known now that the doctor was less interesting.

"See ya' later," she said, ruffling his hair so that the locks became disarrayed.

Thor grinned at her nonetheless, enjoying her company, and very glad to leave. He didn't say anything while Steve carried him out. The older man had already exchanged his pleasantries with the woman, and had barely turned to see Thor trying to escape out the door again. In two steps he had been over, apologizing to the doctor for the trouble, mentioning something about perhaps meeting again later, and then Thor was back onto his shoulders.

Thor pouted again, rebelliously putting his thumb back into its rightful place. But as Steve opened the door to leave, Thor turned one last time, and then timidly waved good-bye to the small woman. She smiled back, and then returned to whatever she was writing down before.

Outside, the two-men and the woman stood up straight from where they had relaxed against the wall. Thor smiled at them, but frowned again at their concern. So much concern; perhaps he really was dying.

He laughed to himself again as Natasha approached to talk to Steve. He wasn't dying. His mother would be with him if he was.

And Loki; couldn't forget Loki.

He frowned; he was really beginning to get attached to that small being.
