Never Saw It Coming

You were always a bit strange. Growing up you were an older sister and always felt like you were ment to protect her. Now you were 21 and couldn't dawdle on here. She was grown up and could take care of her-self. You thought that until today, the day that the Chitari invaded New York. You were working in the Stark building when you saw a man you never seen before. "Sir?" you say. "You are not authorized on this level." "Oh but I am authorized and you can do nothing about it" says Loki.
