"Is it madness? Is it madness to expect you'll have a bloody modicum of sense? You no longer get to decide when I have done enough!" Loki shouted, shoving Thor again. "I am no child that requires the protection of his big brother, and no weakling that must hide in your shadow."

He gritted his teeth and leaned in close, his eyes wild. "I am a knife in the darkness, brother, and you had best start considering what that means now."

Abruptly he released his brother, yanking his hands from Thor's grip in one swift motion. He stepped back rapidly. His voice dropped low, filled with bitterness. "Though the contempt with which you view me and the strength of my love for you never ceases to amaze me."

He barked out a word of command in a strange language and stepped through the wall behind him.
