Steve looked around. This had to be the biggest house he had ever seen! Tony had invited him to stay with him because he had no where to go. Tony had told him that he could go anywhere, but his room was off limits. Steve was now wondering aimlessly. Steve had been here for over a week and he still couldn't fine his way around the place.

"Jarvis?"

"Yes Mr. Rogers?"the humanoid voice answered back. Steve still couldn't believe that Tony could make something like this. It seemed unbelievable, unfathomable, but then again this was not his time. He should have been one of those old guys that had their grand-kids teach them how to do this. He could almost laugh at the thought.

"Do you know where Tony is?"Steve replied.

"The last I saw or heard of Mr. Stark was when he was in the lab. He might still be there,"Jarvis implied.

"Thank you Jarvis,"Steve smiled at the ceiling.

"My pleasure Mr. Rogers,"Jarvis left it at that as, again, Steve wondered aimlessly. This place was just too damn big! A thousand plus people could fit in here. And that was only on the first floor! And there wasn't anybody who worked here more than part-time. It was crazy! Hell, even Pepper didn't stay as long as normal workers. Then again Tony did have a special place in himself for her. But only they knew where that special place was. And, for some reason, that pissed Steve off.

While lost in thought Steve walked right into the laboratory doors."Ow, stupid doors. Why are they so hard?"he almost faced palmed for that, but decided against it for his face was already in pain. So instead of doing that he walked into the lab.

"Tony? Tony, are you here?"Steve called out. There was no music playing like usual, his Iron Man suit was gone, and the window was wide open."He snuck out?"it was more of a question at first."He snuck out. Hey! He snuck out! What the heck!"he shouted enraged. He thought about braking some of the chemical viles then decided against it. He didn't know what were in these viles. It could morph the super solder serum and make him into something he didn't want to imagine.

In the middle of him trying to vent there was a bright flash. After a moment of being star-gazed Steve looked around. Nothing seemed out of the ordinary until a flash of green and gold caught his eye. He turned on his heel to see Loki. He was coughing because of the smoke being created around the room. Thinking quickly he picked up a peace of metal fragment from the Iron Man suit and threw it.

Though blinded Loki was able to sense the danger approaching. He nimbly dodged the metal, but at a cost. When he dodged he reviled a green vile that was hit instead of him. Steve let out a curse as the vile wobbled and fell over. Another cloud, this time of green gas, blinded them. When the cloud dissipated Loki was gone and there was, thankfully, no evidence of the spilled liquid.

"Jarvis do not tell Tony about this,"Steve almost pleated.

"Yes Mr. Rogers,"Jarvis complied. Steve sighed in relief. That was good. Then he was enraged yet again.

"Jarvis can keep a secret can't he? But when you tell Tony to keep quite he just has to open his mouth! Stupid Tin Man! He's always causing trouble,"he grumbled throwing his arms up.

"Who's causing trouble?"Steve turned in time to see Tony, in his suit, climb back into the window. Steve watched him before making a sound of annoyance and fleeing the room. Tony made a confused face before shrugging and getting Jarvis to help him get the suit off.

Not long after burning himself out, by working out, he felt waves of extreme exhaustion. He couldn't explain it, but it was awful. And it was only mid-day! It was very odd. He was never this tired before. So instead of fighting it, he went to take a nap. It took him a while, but he finally was able to find his room. Among other things which were never to be spoken about. Ever.

Steve woke up sometime later. He felt...off somehow. It felt adorable and awkward and he felt like it would change him forever after this. And he wasn't sure it would be in a good way. As he stood to go was up his legs felt like jello. He almost fell a couple of times. Steve's eyebrows frowned. This was not like him at all. All shaky and weak and... he suddenly jumped up and ran to the bathroom. Had the serum worn off? No that was impossible. Wasn't it?

Throwing open the door and flipping on the lights Steve stared at the mirror. He looked the same. Nothing different, but something waving and blonde behind him caught his eye. He turned his head to see a tail at the nape of his spine. He started getting confused and a shrill whine sounded from the depths of his throat. He froze before slowly looking back into the mirror to get a better look at himself. Atop his head were two floppy blonde dog ears. They were flattened to the back of his head. He suddenly knew what was going on.

"Tony! Tony! TONY!"Steve ran down the hall, up the stairs, and to his door screaming his name. Tony came out with a mad look looking for him. When he spotted Steve he was covering his head and running around.

"What do you want now?!"Tony shouted. He wasn't very angry, but for some reason when he heard Steve he got pissed. Like Steve had done something and hadn't told him. Maybe it had something to do with the broken glass he found in his lab. And when he asked about what happened Jarvis had said nothing.

"Tony we, uh, got a problem,"Steve said slowly. Almost frightened.

"And what may that be pray tell?"Steve slowly removed his hands from his head. Tony watched carefully as he did. The look of astonishment fell upon his face."You have ears. Dog ears,"he said slowly. Steve nodded assuring him of that fact."What did you- what did you brake in my lab?"

"I-I don't know. Loki appeared and I threw something and a green vile fell over and, and, and then this!"he turned pointing to his tail.

"G611! You broke G611! That's what happened when I was- why didn't you tell me!"he shouted. It all made sense now. The broken glass, the unknown anger, the reason he was in the lab in the first place.

"What are we going to do!"Steve whined.

"Uh fix it of course,"Tony said in a duh tone.

Next chapter you'll find out what happened to Loki. Cause I just love Loki so much!
