"Thor, stop. Never imitate me again."

"But brother, I was affecting your charisma and charm!"

Natasha smirks. "Tony's right, he did sound a lot like you."

"Hey Stark!" Steve calls from the doorway to the kitchen where he was watching the display. "You got any food in this joint?"

At the mention of food, Loki's stomach gives a very loud growl. Thor looks like he is fighting to not laugh.

"...Sustained magic takes a lot of energy," Loki says, trying not to blush in embarassment.
