I won't bother adding to the "mess with Loki unprovoked and watch how fast we take you down" crowd. I will say that the man is one of my closest friends and has been nothing but considerate of my family and me since we arrived. I made him my baby girl's godfather because I trust him implicitly.
So please remember that, as hurt as you've been, there are two sides to him. He knows what happened in New York. He regrets it, even if it isn't this current Loki's doing. And he has worked his ass off to not be that man.
