Explanation
"What the fuck?"
Loki looks over to Tony. Then he looks back at Thor. And then he sweeps the court room.
"Since when do Midgardians come to Asgard?" He asks. Before anyone can respond though, his eyes widen and he looks back at the Chitauri soldier. "What did he do?!?"
Thor grimaces and he responds, "He attacked Midgard. With an army of Chitauri soldiers. With the scepter. That has the mind gem in it."
Loki just stares at Thor for a minute. The entire hall is dead silent. Nobody moves or speaks in fear of what Loki will do. Loki slowly turns around and faces Odin. Then he turns back to the soldier on the floor. Then to the Avengers. Then to Thor.
He opens his mouth and instead of outrage comes a calm question. "How long has he been here?"
Thor, of all people, responds, "I- what? Why?"
"Just answer the question Thor."
Thor hesitates before speaking. His eyes glance at the corpse and then responds, "A few days."
"How many days?"
"Why does it matter? You are here now! Surely not responsible for the attack on Midgard!"
"Thor! How many days?!?
"5 days."
Loki closes his eyes and closes his eyes. He lets out a slow breath of air. Then he lets out a curse that startled Tony, "Shit."
Odin speaks to Loki, "Loki, what is the meaning of this?"
He turns around and gives Odin a blank look, "You should have killed him sooner."
Frigga lets out an anguished 'no.' And then speaks, "We could not Loki. For you are our son and we would not inflict such a punishment on you."
Loki gives a soft but unforgiving look, "You know the laws better than I, mother. The punishment for the attack on Midgard is death. Not even I am above that law. And now because you ignored it they are coming and will slaughtered all Æsir where they stand."
Thor exclaims, "What? Nonsense! The Æsir are warriors! We will fight them to their deaths surely!"
Loki turns to look at Thor and gives him a soft smile that quickly fades away. His eyes cast downwards for only a second before he looks up at Thor directly, "Your faith to the Æsir will always amaze me Thor. Where he comes from is dark and empty. He is a beacon in a desolate world. Where he goes, his species will follow. They search for a way back to Yggdrasil and he gave them one. The Chitauti will come and they will destroy all who stand in their way. No mercy for those who are captured, they kill for fun. I hope you are right Thor because if they do come, it there will be war."
Right then a booming voice was heard, "Ah. My pet, you are the one who destroyed my toy. You will pay for that." A portal opened and Loki cast his magic around the room. A few protested but were quickly quited by what Loki said next.
He spoke loud enough for all to hear. "Do not move and do not speak. It will shatter the illusion. If he thinks you are dead, you are safe. If you are not, well it's not good for you."
With that he turned away and faced the portal. Everyone, except Loki, scanned the room with their eyes. It appeared as Asgard had fallen and all of its citizens with it. Except it hadn't. Frigga's and Odin's eyes went wide. A large amount of energy had to be used to be able to create such a large and detailed illusion. Loki didn't look the slightest bit tired though.
Odin lay dead on the floor by the throne. His body bleeding out to the floor, a spear sticking out of his body. Thor's was crushed under the heavy weight of his mighty hammer. His hands resting on top as if he tried to remove it but failed. Frigga lay not to far from Odin. Her neck was at an odd angle and there was scorch marks from magic. The Avengers were killed on the spot from arrows and daggers. The other Asgardians either crushed under the stone of the castle or dagger wounds. Loki's type of a dramatic scene sure did work.
Chitauri soldiers flooded out of the portal. They scanned the room and looked at Loki. He had cast and illusion of himself covered in blood. It looked as if he had just battled the entire entity of Asgard. Looked convincing enough to everyone.
Except the Chitauri.
