The second the door of your jet closed, you exhaled the breath you had been keeping in. This was going to be a hard mission for you.

You started the engine and all the other systems you needed to start so you could take off. Before you started rolling you yelled at the two to not do anything stupid while you were gone. You took one last glance before you took off, noticing Loki still watching your jet. You waved but you didn't think he noticed.

As you were flying your mind kept wandering to Loki. You had barely been gone for five minutes and you already missed him.

'You should have told him (Y/N)!' Your thoughts scolded in your head, 'You should have told him your feelings before you left! This is a dangerous mission, even for you! Think about where you're going!"

You shook your head in an attempt to rid yourself of these thoughts. Instead you thought of the mission ahead of you, and where you were going.

They said they had a lead. Fury had told you that your sister had been seen near the place you were experimented on, going in that direction. God damn it, you didn't want to go back there. They made you how you are. They made you hate all that you are, and you never wanted to go back. But if it meant finding your sister, then you would take the chance.

The memories of that place came flooding in as you remembered everything you had been through.

Your parents going missing.
Living with your best friend.
Meeting your sister.
Best student in your year at High School.
Wonderful college plan.
Being caught.
Torture.
Becoming a monster.

You cringed at the memories. You remembered screaming at nothing to help you, all the injections and the searing pain that scorched your veins daily. You remembered the day you realized your powers. They had let you up for once; out of that horrible, metal chair that had served as a prison for weeks. Maybe months. You had been taken to a secure facility where they had tested you on your abilities. You remembered running fast for the first time. It was like everything in the world moved at the pace of a snail and you were a cheetah. Then you found your strength. You had benched nearly a thousand pounds. It scared you.

Now all you wanted was to be free of what they did to you. You felt that what they had done to you kept you tied to them, so you desperately wished to be normal again. To be who you were before them. No strength. No speed. Just you and your wings.

Now that you were thinking about it, thoughts of Loki seemed like a better option. Or maybe your sister.

You two had only met once when you were eleven. She was in an orphanage while you lived with your best friend; Sarah. You were younger than her by a year.

The visit had been arranged by Sarah's mother and the lady who owned the orphanage. Ms. Tipling if you remembered correctly. You were thrilled to know you had a sister. Her hair was ginger and she had freckles all over her cheeks and arms. Her eyes were brown like dark chocolate, and her smile lit up the room.

You loved her.

There was another time that you had tried to visit her in that orphanage. She wasn't there. She had gone missing without a trace.

Ever since then you had been trying to find her. Using all the resources you had to find her. Once you had joined S.H.E.I.L.D., and eventually the Avengers, you had asked for help finding her. Fury had given you help finding her, but it was to no avail. She was still missing.

Now you took every lead you found, every tip you got to find her. She was all you had left of your family and you weren't about to loose her.

With all your thinking you hadn't realized that you were nearing your destination.

With a quick decent and landing, you climbed out of the jet, grabbing your sabers and guns. You headed to that awful building that never left your memory.

It looked like any old abandoned warehouse on the outside, but on the inside it was one of the most secure bases you had ever come across. It did an outstanding job of camouflaging itself with the terrain.

Not seeing any outer guards, you dashed to the back door at speeds that made you invisible. Quickly, you hacked into the locking system on the door and the security system, disarming all the alarms and protocols before unlocking all doors in the building.

You walked in, still not seeing any guards. That was strange and you didn't trust it. You drew your sabers from their sheaths, and brandished them at your sides. The hallway you were in was dark and long. You couldn't see more than ten feet ahead of you, and the ten feet you could see were dim as it is.

Your wings were tucked behind you as tight as was comfortable so you took up less space and made less noice.

At the end of the hallway there was an open and nearly empty room which you recognized from your memories immediately. It was the room in which you were kept. Even the metal chair you had been kept in was there. Keeping to the walls you walked around the room. You looked for any sign of your sister. Any at all.

It was in a split second when you were attached. Guards coming from left, right, and all other directions available. Oh look! There are all the guards! You swiftly opened your wings and took to the air in the tall room. You flew down quicker than any of them expected, slashing them before they realized you had moved. They fell like dominoes as you flew around the room. All save for one.

You were flying, taking out guards faster than imaginable, when you felt a burning pain in your right wing. You fought it, trying to ignore it, but it was too much. Your wing gave out and you fell.
