The Avengers

It was a sunny day, everyone was sitting relaxed. No, seriously, everything was fine. The Avengers were doing their own thing, even Loki himself. Tony was doing something in his office as usual, Thor was drinking, Bucky and Loki were chatting, Bruce was in the lab, Natasha was in the living room watching a movie with Wanda. Rogers was playing PlayStation with Peter, while Strange was back in the room. It was quiet. Perfect, a day off.

A scream echoed outside. A woman's. Those who heard it jumped up, except Loki, who couldn't care less. The Avengers immediately gathered and went outside. It was already chaos.
Tony: "Well, it seems like no one can live without me and my beautiful view outside."
Tony said with a grin.
Steve: "Oh, shut up already, unlike some people, I almost won against Parker."
Steve said disappointedly.
Peter: "Oh, come on, let's talk about that already, maybe we should start figuring it out?"
Parker muttered under his breath.

Everyone moved forward, they surveyed the area. But they couldn't find anything. Strange, but what was causing the chaos? And then there was the screaming. A woman's. A person was standing on the roof of a high-rise building. Strange. The neighboring building began to crack and collapse. Everyone immediately rushed to save people.

The man on the building disappeared, but once the disaster was over, they all began to wonder who it was. When Loki was told this, his expression darkened slightly. There was no smile. Only mild irritation and shock.
Loki: "What color is your hair?..."
Steve: "I don't remember... What?"
Loki: "You need to try to find this person..."
Steve: "Why?"
Loki: "This is my sister..."
Thor: "What do you mean?"
Loki sighed but still answered, his voice shaking slightly.
Loki: "I used to have a sister... A younger one... But she disappeared... Only memories remain... The last time I saw her, she swore that she would find me... And then no one saw her... I... I thought she died!.. But it seems I was wrong..."
Thor: "Wow"
Loki nodded slightly, a shudder running through his body. Would she really find him? And what would she do with him when she did? So many questions. So many. But so few answers... Or rather, none at all.
