Thor 2 - The Dark World

Dr. Erik Selvig: "Your brother isn't coming, is he?"
Thor: "Loki is dead."
Dr. Erik Selvig: "Thank God... I'm so sorry."

Volstagg: "If you even think about betraying him..."
Loki: "You'll kill me? Evidently there will be a line."

"Well done, you just decapitated your grandfather!"

"You lied to me! I'm impressed."

"You must think I'm a piece of bread that needs to be buttered so heavily."
