It was already past 11 pm when alarm sirens went off in an outdoor area of S.H.I.E.L.D. In one part of the building complex, a dark figure with headphones sat on a bed with a laptop standing on her lap, forming the only source of light next to a small night light next to the door. At first, as the person listened to the music loudly, she didn't really notice the siren howl, but when she felt the excitement in the corridor outside her door, she took the headphones out of her ears and tried to pinpoint the cause of the excitement. She didn't understand, however, because the door to her room was a special security door, in her case a slightly thicker door so she wouldn't be able to get away easily. Now, however, the door opened and Agent Maria Hill followed by two armed SHIELD agents entered the room: ''Get up, pack up your stuff quickly, we go,'' ordered Agent Hill, the person who kicked her off the bed out, looking slightly irritated.

"Why?" asked a voice that seemed to belong to a 16-year-old girl, from the bed and under the hood of a dark gray hoodie, a pair of dark blue eyes came to light.

''The Tesseract spins around, so everything is evacuated. Director Fury has instructed me to take you to the helicarrier,'' she replied, impatiently waiting for the person on the bed to follow their instructions. A mumbled '' Great, '' was heard before the person got up, packed their laptop in a backpack next to the bed, then pulled out a small travel bag with the SHIELD logo under the bed and out of the closet, across from the bed, Wrapped some clothes before shouldering both: "Come on, if I have no other choice," the girl said, but so far she could only tell by her voice and by the fact that she had packed some bras. So the four ran to the trucks that they should bring out here, but before that, the 16-year-old, but the opinion was still to make a small stop at the Tesseract. Knowing that Agent Hill wouldn't allow her to do so, she used a very simple ruse: "Shit, I've got something left in the lab, which I can't leave here. Can I get it fast? I'll be right back,'' the 16-year-old tried, and after a moment, Hill nodded with an annoyed expression: ''Go, but come back right away, we need to get out of here.''

Just as Clint Barton was talking with Director Fury about the Tesseract and its portal capability, the girl entered the lab.

"A new surge, doctor," cried a blonde woman in a white lab coat, and Erik Selvig ran to her and looked at a monitor. A jerking, went through the whole building and in some places, the plaster trickled from the ceiling.

Suddenly, the Tesseract opened a portal, which closed again with a huge energy discharge.

The 16-year-old was still a bit hidden in the entrance, but the wave of energy also hit her.

''That was not so good,'' she mused in her mind and already noticed very slowly how her abilities made themselves felt again. As she turned her gaze back to the small podium where the portal had opened, a young man with shoulder-length, black hair knelt there, in a strange lift, almost like a medieval one.

But her attention went directly to the scepter, or spear in his right hand, in which a blue energy source was processed.

''Sir, please put the spear away,'' Fury first turned to the strange man, who looked at the object in his hand and then shot at the SHIELD agents who had approached him in order if it posed a danger to harm.

A ferocious fight ensued, and in fact something like that would cause any ordinary person to go out to survive, but the 16-year-old sneaked into the room and hid behind some technical equipment and computers, hiding the stranger with the spear not out of sight.

When Hawkeye rose from the ground after rescuing himself and Fury from a spear attack and attempting to attack the stranger, he grabbed him by the wrist and tapped his spear on Clint's chest. His eyes turned pitch-black for a moment and then turned bright blue, whereupon Clint relaxed as far as a killer could relax and put his gun away. He repeated this with another man who was also responsible for laboratory safety.

In the meantime, Director Fury had taken the Tesseract out of its holder and packed it into a special suitcase he wanted to go with, but the stranger didn't let him: "Don't, I need that."

Of course, Fury tried to stop the stranger because the building complex had been damaged by the portal opening and closing and was about to collapse.

''I'm Loki from Asgard and a glorious request is my burden,'' Loki finally called his name.

With that name, the girl could do something in her hiding place. From S.H.I.E.L.D files she knew that Thor's brother had to have his, which Selvig confirmed again shortly thereafter. When Loki began to talk about freedom as the big lie of life, the girl decided to dare to leave her hiding place, realizing that Barton realized that Fury wanted to stop the squad until the building collapsed.

Fury was the first to notice the 16-year-old and his eyes darkened when he realized who she was. Apparently he thought she had something to do with Loki's appearance, but this time, she was really completely innocent. Seeing the change in Fury's facial expressions, Loki turned his gaze in the direction Fury saw, and when he saw the little figure there, he was distracted. This was not because another person stood between him and his target, but because of the invisible energy that surrounded and seemed to flow through the person. Loki knew such energy, but only from his adoptive mother, Frigga, and other sorcerers, but none of them gave them that energy.

When Loki's mind returned to normal, he asked her her name.

"You can call me Shadow," she answered, and for the first time, she removed her hood, so that you could now see her chest-length, hazel-browed, wavy hair. Before anyone could say anything else, Selvig said, which in the meantime has also been brought under the control of the scepter: "The portal collapses. We may have two more minutes to get critical. "With the words, '' Well then ... '' and a sidelong glance at Barton, who drew his gun and fired at Fury, the four men made off in the dust.

But before that Loki turned to Shadow again: "I hope we'll see each other again, Lady Shadow," he said, grinning, but Shadow realized that it was more of a promise, which made her smile despite the situation because she had once again unconsciously achieved her first goal.
