Tony's POV

        "So, you have powers? Why don't you show us? Aside from the random evil chick 'cause we've seen that one." I said, causing everyone to scowl at me. (Y/n) just laughed weakly. We had been teaching her what words actually meant and how facial expressions actually worked and... she'd been explaining to us why she thought the way she did. She was finally getting used to civilian life and had recently told us that she had "special abilities". So, as a result, we'd been begging her to tell us or show us what they were. She didn't enjoy using them, that was clear.
        "Okay. But... I don't know. I feel strange using them... or telling you about them." (Y/n) mumbled nervously, trying to look anywhere but at us. We assured her that everything was alright and so she proceeded to tell us. No demonstrations, just explanations. In the end, we learned that she can summon fire (in any shape) at will, run faster than anyone, and she can bend reality however she pleases. We were at a loss for words in the end. She said that she would demonstrate if times ever called for it and that, until then, she would like to be trained to fight. So we trained her, daily, nightly, any time she needed to be trained. I think it helped her get used to us and her new life and was a way for her to momentarily forget everything.
        "Harder!" Steve shouted at (Y/n) as she continued to hit the suspended punching bag. Then, all of a sudden, she punches a hole straight through it. She instantly retracted her hand.
        "I... I think I need to sleep. Goodnight. We'll train more tomorrow." She whispered, almost as if she was saying it to herself. She looked up at Steve, a look of pain on her face.
        "I'll fix that tomorrow." She told him, leaving the room. Steve and I watched her leave, then turned to the gaping hole in the punching bag that was leaking sand all over the foam mat on the ground. I was so floored that I barely even noticed what had just happened. I walked out of the room and saw her going into Thor's room, closing the door behind her. She had been talking to him a lot lately and it was helping her out a lot, too... I think. Point was that she wasn't getting any worse, but I could tell that there was still something bothering her. I chose not to ask her about it just in case it wasn't something she wanted to discuss.
        "Tony." I heard from behind me, tearing me away from my thoughts.
        "Yeah, Cap? What's up?" I asked, trying not to sound worried. I was supposed to be the one that laughed all the time, the one that didn't care about anyone but himself. Truth of the matter is that I do care. I care about a lot of people. I just know that if I showed it, it would be yet another obvious weakness to deal with.
        "Look, I know she's been nice to us since the day we got her. No outbreaks, no nothing... but-"
        "But what? You think we can't trust her? How many times has Banner gone nuts and how many times have we stopped him? And now, now of all times, after we've been attacked by this girl once, you want say we can't trust her?" I argued, glaring at Steve. He sighed and turned away.
        "Look, just forget I said anything. I'm sure we'll be fine." He scoffed, walking away from me. I followed behind until he went to his room, then I went over to the workshop.
        "Ah, Mr. Stark." Vision said upon my entrance. I sighed, heading over to one of my large machines. I instantly began to work on it, paying no attention to anything else.
        "Mr. Stark? Is something bothering you?" Vision asked, floating over to me.
        "No, Vis. Please just let me work." I grumbled, grabbing a wrench from a nearby table. I couldn't help but think of what Steve had said earlier. What if he would just keep getting worse about others? What then? What if... (Y/n) is the last one to join the Avengers? Cap should know that everyone is dangerous in this group, he should know better than to judge people upon their actions!
        "Tony?" A soft voice broke the silence.
        "What!?" I yelled, clearly annoyed. That's when I noticed that it was (Y/n) standing there. She seemed terrified and it truly hurt me.
        "Hey, I'm... uh, sorry about yelling at you, Shirley Temple-"
        "Shirley Temple? Is that the nickname you've given me?" (Y/n) chuckled, walking over to me in the darkened room. I showed her Shirley Temple after I figured out I wanted to give her that nickname. That way, she'd know who I was talking about.
        "Yeah. 'Cause you're so... I dunno... innocent? I guess? You've gotta give me time with these things." I laughed back, handing her a wrench. She looked at me with a confused expression.
        "I thought it was about time I taught you how to build and engineer. Let's get to work. I'll help you on anything you'll be needing help with." I smiled. She seemed surprised, but she smiled back at me, taking the wrench from my hand shortly after. We worked long hours into the night which (Y/n) seemed to enjoy. We talked about the books she was reading (and already had read) while we worked. We talked about movies and common interests until (Y/n) yawned. Her yawning made me realise just how tired I actually was. I was about to suggest that we go back to our rooms, but she had already fallen asleep leaning on one of the tables. I knew that I couldn't carry her to her room without waking her up, so I settled for the next best thing. I went out and grabbed a pillow and a blanket, then proceeded to lay her down on the ground gently. I lay out my own little palett on the floor and, eventually, fell asleep.

I'm sorry if this story turns out to make no sense (or already doesn't). I'm not that good with timelines or things that have happened within the Marvel cinematic universe. For all I know, this could all be absolutely wrong. Bear with me, it'll make sense eventually... probably...
