My fault (The true story of Ultron and a buncha chaos)

Come on, Jarvis

POV: Loki

Ah, peace and quiet and mischief.

I'm surprised no one's awake, but I'm sure not complaining. Most of the more interesting rooms are locked, like Tony's lab, but it's still nice having free reign around the tower.

The kitchen knives are pretty small, but I do take one and it fits, well hidden, in a pocket on the inside of my cloak. I did leave my cape in my room, which is slightly disappointing. I hope young Peter isn't too mad at me. Of course, opportunities come up, and I can't just ignore them. I'll only be an hour or two, until everyone starts waking up and the absence of two people is suspicious. I can't promise I won't switch identities with one of them, but keeping them both quiet will take a lot of effort. Especially the young Spiderling.

I hear footsteps and instinctively make myself look like him, just as Cap rounds the corner. I try to remember everything about the interactions between the two. He calls him Mr. Rogers, and something about his shield doesn't make sense...

"Morning, Pete. Why are you up so early?" he asked. I quickly thought of what the kid might be doing.

"Homework," I said, hearing Peter's voice.

"Huh. You need help?" he offered, looking out a window at the sun peeking through buildings. Oh, dang it.

"Uh, no. I'm fine. How does your shield bounce?" I said, trying my hardest to sound exactly like Tony's intern. And believe me, my hardest effort isn't detectable by any Midgardian or their machines. Ask Shield.

"I'm pretty sure it just defies physics. Like mol-near," Steve said, in a way that I knew meant he'd thought about it for a while.

"Mjolnir?" I almost stop myself, sure I'd made a mistake, before remembering that Peter had pronounced it right before.

"Yeah, that's what I said. Well, good luck with your homework?" 

"Thanks," I said, before leaving as quickly as I'd let myself. Maybe I shouldn't impersonate someone I don't know very well. I took off the illusion the moment I was sure I was alone and fingered the knife in my pocket. I would love to stab someone, but I'm pretty sure that would end in me locked in my room again and the knife confiscated. However fun that would be, I'd keep the knife until I needed it. After all, there were petty thieves and muggers all around the city, and if I happened to spot one of them stopping them with a knife wouldn't do anything but good to my name, as long as I remembered where I can stab them.

"Sir?" Jarvis said. I stopped. Ah yes. Cameras, I'd forgotten about them. Might as well note that Heimdall could be watching as well.

"Please don't tell them," I said, trying to stay calm. "I'm not going to kill anyone. I-"

"I'm afraid I can't allow you to have weapons. Mr. Stark's direct orders. Now, if you would put it back-"

I ran. Kind of hard in a cloak, but a lot easier without the cape on. I heard my brother snoring in a room, and completely ignore him. Not my concern right now, although maybe if I had a sharpie instead of a knife I would care. I get to the front door and remember last time, so I open it with the blade of the knife instead. Not locked. I allow myself a smile but the moment I see the busy street I remember exactly who I am and exactly what all these mortals think of me. Ohhhh crap.

I put on the illusion of some random Midgardian and continue walking on the sidewalk, keeping as much distance as possible between me and Avenger's tower. That was it, death faking time. I'd messed up, they knew I was willing to manipulate them all and steal a knife for a fact now.

I collapse on a bench after perhaps ten minutes, enough so anyone who might've seen me as Loki won't be anywhere near me. It was, to say the least, utter madness. Definitely no peace or quiet here. The bracelet on my wrist seems to be more obvious than ever, although no one seems to care that I exist. Is this normal for Midgard? If it is, I understand why they all seem to have nothing better to do than make frisbees out of vibranium and give magic confusing names.

I honestly don't know what to do now. If I had the tesseract, that would work absolutely fine. I'd find myself a planet in need of ruling, get a small army to put myself in charge, and I'd never have to see any of these people again. Easy. Of course, That is an infinity stone, so... probably not going to work.

I look at the sky, the blaring sun making me sweat. It was only May, but it had been especially hot outside lately. Of course, that wasn't a problem, and I honestly didn't care that much.

I thought over my options again and landed on one thing for certain: I would not be able to go back there until they think I'm dead or not trying to take over the world. At least, not-

My notebook. Of course. Why had I forgotten? He's almost what started this in the first place. I couldn't leave it there, not with all the Avengers. Peter was okay, but the rest of them were a bunch of idiots who'd take death and destruction over a simpler way of life. Although honestly I'd hate to have to be in charge of all these Midgardians, I would like someone to kneel. And that would surely never happen if they knew what I was writing in there.

"Heimdall?" I whispered into my scarf so no one on the street would hear me and think I'm insane. I couldn't think of what I wanted to say next. Can you erase my notebook or something? What?

I couldn't think of a way around it, I'd have to go back. As if things didn't seem hopeless enough, now I'd have to go right back and return this stupid knife. 

I get up and start walking, ignoring everyone around me. Hardly a moment after I get up, the world turns into strange glass-like fragments of itself,  and the ground in front of me drops to a deep well of emptiness. I turn around, looking for whoever did this.

"You know, I can't say I'm surprised to see you here, Loki."

Alright, I'm going to add characters left and right. I have no idea where this takes place in the MCU, but just deal, y'all. Just deal and enjoy the story.
