"Loki by Loki" by Tom Hiddleston :D . If Happy Hiddles doesn't make you happy, then you are beyond the help of mortal men >>> I just want to protect this man and huggle him and keep him safe from corruption. In the least creepy way, of course.
Not only this but in the Thor movies lokis eyes are clearly green but in avengers they look blue we can see with hawkeye and others that your eyes turn blue under the control of the scepter - Loki Theory
Now you're just some brother that I used to know! Hahah I'm so glad I'm not the only one who think of this song :'D As soon as I saw Loki in the new Thor trailer, I wanted to sing "now you're just somebody that I used to know" x)
