"Tony, stop!" Natasha commanded, hand gripping her gun. Thor turned to face Loki, his face red with anger.
"Loki stop! Release your control of Stark, or I shall make you!" He bellowed. Loki's face drained of color and he swayed on his feet, but he did nothing, and could not speak.
"Now Loki!" Thor banged his fist hard against the cell, and it promptly shattered. Clint drew his bow, pointing the arrow at Loki's neck, however the Trickster did not move from his tense position.
"What kind of brother are you?" Tony shouted into Thor's face. The thunder god turned to him and frowned deeply, as though he didn't understand why Tony would ask such a thing.
"His eyes aren't weird like Clint's were..." Bruce said, trailing off at the end, however everyone heard him.
The room grew quieter.
"I asked, what pathetic excuse of a brother are you?!" Tony shouted again, eyes wide and nostrils flaring. He couldn't remember being this angry in his life.
"Friend, if you are nay being controlled, I know not what you speak of..." Thor trailed off.
"How long have you lived with Loki, Thor?! How long?" Tony was waving his hands, left leg twitching slightly as he spared a glance at the trickster; still standing exactly where he was, though it looked like he might pass out at any given moment.
"I-" Thor was promptly cut off by Tony's next words.
"I pretty fucking long time I think."
"Aye, but-" Again he was cut off.
"Tony-" Steve began but was ignored.
"So how could you not remember what color his eyes are?"
A deadly silence filled the room, seizing it's occupants in a choke hold, and remaining there. Thor stood, his mouth open slightly, eyes fixed on Tony with a mix of shock, confusion, and dread on his face. Clint had lowered his bow, Natasha her gun, and the rest of the Avengers stood in quiet horror, staring at Thor with disgust. It was when Loki crashed to his knees, a tormented whine emitting from his bound mouth, breaths coming in short gasps, that the silence was broken and Tony leapt into action, running through the barrier of broken glass and catching Loki before he fell further. Loki panicked, beginning to struggle in Tony's arms, pleading something that the surrounding Avengers could not make out. Tony did not relinquish his grip on the god's torso, and could not explain his sudden protective urge over Loki. Reaching behind his head, Tony unclasped the muzzle that covered the crying god's mouth. At that, Loki went scarily still.
