"F.R.I.D.A.Y," Tony spoke as he pulled into the driveway of his rebuilt Malibu home as the sun started to set, parking and turning the engine off, leaving him in silence until he spoke again. "I don't have anything to do for the rest of the night, right?"

"Doesn't look like it, Boss." F.R.I.D.A.Y reported. "You have the night all to yourself."

"Thank god." He mumbled before he slipped out of his car, shutting the door and began to walk to his front door. His home looked the same as it had been before everything went to hell. It was identical and that was good in Tony's mind. He reached forward to open the door.

"Boss," His trusted AI sounded from his Stark Phone, making him pause. "There's someone inside."

"Can you get a read on who it is?" he asked quietly, not wanting to give away that he was soon to enter the building.

"No."

"Great. Well, time to meet our house guest." Tony unlocked and opened the door, walking in and shutting it behind him before peering at the couch. He could see a black silhouette sitting there, perfectly still. He knew that whoever this person is, they were staring straight right at him. This person must have been sitting there for God knows how long, just staring at the door, waiting.

"F.R.I.D.A.Y, lights."

The living room lit up revealing, in Tony's extremely professional opinion, an attractive man with brown hair that went to his shoulders and stoic stormy grey eyes. The guy was wearing what looked like to be tactical gear and there was a pair of glasses or goggles and a mask lying beside the guy. What got Tony though, was the metal arm that was attached to him on his left side.

"First of, who are you, Terminator?" Tony questioned; arms crossed against his chest. He watched as the man tilted his head for a moment, as if he had to think about how to answer.

"...Asset." The man finally replied and holy shit, that deep voice could make any man and woman weak in the knees.

"That's...not a name. Seriously, what is it? Who are you?" he asked arms crossing in front of the arc reactor in his chest,

"The Winter Soldier." The man stared at Tony, weariness now showing in those grey eyes. Okay, that Tony can work with.

"The Winter Soldier, eh? I'll just call ya Winter- is it okay if I call you Winter? - and now, what are you doing here?" He got a nod in return then looked up a quiet question hit his ears.

"You are a Mechanic?"

"One of the best."

The man- Winter- held up his metal arm and even from where Tony stood, he could see the damage it had sustained, the wires that was hanging out through the gaps. The sight made him wince.

"Okay, yeah, I understand why you came to me. Follow me down to my workshop." He headed down the stairs, Winter following. The door was already unlocked thanks to his AI and he went inside with the soldier, the door shutting behind them.

"Sit down while I get the necessary tools." Tony stated as he started to gather the tools he would need. Out of the corner of his eye, he watched as Winter sat down on the couch that Tony had left there for when he slept in the workshop.

He dragged a chair over setting it in the proper spot before plopping down on it, motioning the other to hold up the arm. Winter did what he was motioned to do, and Tony got right to work, first examining it and started to work on it.

"Whoever did this arm did a shitty job." Tony scrunched his nose in distaste. "The hell did they make this out of, Vibranium knock-off?"

The soldier said nothing, which was fine with Tony. He just continued to work, his fingers dancing, tools working to fix everything about the arm.

It took him almost a half an hour to finish the repairs and when he did, he stood up, walking over to his desk and dumped the tools on his workbench. "How does it feel?"

"It is..." Winter paused, obviously searching for the right word to use.

"Loads better?" Tony suggested. Winter didn't do anything for a moment before nodding. "Good. Now, come on. I'll show you where the guest room is and you can take a shower then."

Tony then lead him to the guest room and the shower and, once he heard the shower turned on, he set a pair of large sweatpants and a muscle shirt before he walked out of the room and went down to his workshop once more, moving the chair back and sitting at his workbench. "F.R.I.D.A.Y, keep me updated on our guest."

"Of course, Boss."

"Also, get all the information there is concerning The Winter Soldier."

"Will do."

Tony ran a hand through his hair, taking a deep breath before pulling up his current ongoing project- a new suit, plus a gauntlet he could walk around with in case he would be in a pickle and didn't have one of his suits. He needed time to think and what better time to think than working on his suits?

Sometimes, he really didn't like how he wanted to help those in need- and act upon it. It usually leads him into adopting strays or him getting hurt.

But really, when you are Tony Stark and Ironman, what can you do?
