Loki either wore green or black. The only exception was his battle outfit, his inside cape was yellow. In memory of his mother. Her favorite color was yellow. The others say he wears black for style but they are wrong.
     He is mourning. Mourning of the ones lost from New York when he wasn't in control. Mourning for Frigga . Those last words. Those awful last words.
     Green. Envy. He always envied Thor. He envied the ones who has it better. But now, he is wears it out of sympathy. He knows what's it like. To lose someone you dearly love.
Which is why whenever young Peter wakes up crying he is the one to comfort him. Or whenever the Avengers argue, he is one to throw out solutions. He already lost one family, he can't lose another.
     So to see Peter unconscious on the medical table blood staining his already red suit he can't help but let tears poll his eyes. He isn't afraid, he knows Peter will be okay. This brave, smart, amazing boy will be okay. He will make sure of it.
