LOki was looking at the Doctor "Why should I!!" He snapped. He was clearly in a bad mood. "Plus you said you would return soon when I was a child, This is not soon." He growled. 
He was angry about alot of other things too.
THor knew Why his brother was angry, he could see tears forming in Loki's eyes. " Ah yes it is great to see you and Loki is upset lately..., " He didn't know of LOki's dark intentions. "Not just at you."
