The whole thing started at five in the morning, before Tony had had his coffee. He walked into the living room covered in dirt and grease from the workshop, he knew that Bruce didn't like it when he spent all night working on one of his many projects (he had said something about how it was "bad for his health"). As he walked through the living room he was greeted with the sight of a teenage girl asleep on the couch.

"Um, JARVIS, what is a teenage girl doing in the tower?" JARVIS answered his question with "She appeared on the sofa at approximately two seventeen this morning." "What do you mean she appeared?" "It seems as if she teleported straight on to the sofa." Tony sighed as he walked towards the kitchen, he needed some caffeine before he could even attempt to deal with teleporting teenage girls.

When Steve and Bucky walked into the room Buckys reaction was a little different. He dropped the mug of coffee that he had been holding and ran over to the girl who was still asleep on the couch. "Scarlett? Scarlett?" The girl sat up slowly and opened her eyes to see the assassin standing next to her, instead of freaking out like most people would when they saw the Winter Soldier sitting next to them she reached out and hugged him.

Tony walked back in, fifth mug of coffee in hand, "I'm going to assume that you know each other then." He remarked. "So, is she staying here or what?" Bucky looked at Scarlett questioningly. She shifted to look at Tony "If you have room for me than I would love to stay here." Tony nodded as he asked "So how do you even know each other any way?" They seemed to not hear his question as they went to find a room for Scarlett.

Scarletts presence in the tower was a sort of anomaly, but they learned quickly that if you questioned her past you would be on the receiving end of Buckys "I am the Winter Soldier" glare and Natasha's "I know where you sleep" ( the one that Tony swears she can kill small mammals with,she doesn't deny it) Life became an almost sort of normal at the Avengers tower.

Two Months Later

Everyone scrambled out of the way as the Bifrost opened in the middle of the living room depositing Thor in the center of ruined carpet it left.

"Friends! I have come to-" His speech was cut off as he noticed Scarlett standing in the corner of the room, "Lady Scarlett," He adressed her, "Loki did not tell us that you remained on Midgard."

Scarlett fidgeted in her corner trying to think of what she could say to preserve the situation, she had been hoping to put of the issue of her past as long as possible, but before she could say something Tony did it for her.

"Wait, what? How do you know Thor?" Tony looked back and forth between the two. "Lady Scarlett is a brave warrior. She is the holder of the Infinity Stones!"Thor looked confused."Did she not tell you of her past?" Scarlett stepped forward as she realized that there was no way to avoid this.

"Look I'll explain everything. But first we should probably all sit down." The Avengers all moved back over to sit down as Scarlett started to talk.

"My mother was a Valkyrie and my father was a, um, Jotunn, or a frost giant." Her voice lowered to a whisper as if she was ashamed of her heritage. "I was never supposed to exist, but I did nonetheless. I was a child of forbidden love. I was dangerous a threat to both the Asgardians and the frost giants as I was destined to hold the Infinity Stones-" Clint interrupted her "The what stones?" Scarlett sighed "There are six Infinity Stones: power, time, reality, space, mind and soul. Back before the universe was first created there were the six stones, each one of them is connected to one of the aspects of the universe. All of them are immensely powerful." She paused and Bruce nodded, gesturing for her to go on with her story.

"My mother left me on Midgard in the form of a human child, her last gift to me being the Soul Stone. I was young and naive, I used some of my power to show off to the other children at the orphanage she left me at. When Hydra came to town they took me with them, hoping to harness my abilities and become immortal." Her voice faltered as she spoke about Hydra.

"They experimented on me in their attempts to retrieve the stone. There was no way that I could give them what they wanted. I had no idea of what I could really do, I wished for death, little did I know that my mothers gift to me had made me incapable of dying." Bucky and Steve moved closer to Scarlett in an attempt to comfort her.

"When Bucky wasn't in the ice we shared a the same cell. I tried to get him out when I escaped but they watched him more closely than they did me." She smiled ruefully as she continued. "I had no idea what I could do, I teleported away blindly with no real purpose. Luckily for me I ended up on Asgard where I met Loki. He taught me how to use and control the full extent of my abilities. How is Loki anyway?"

She turned and smiled at Thor, her momentary sadness forgotten. At this question Thor looked nervous. "Loki is the reason that I am here. The All-father wished for me to inform them of Loki's-" At this he faltered. "Loki's what? Thor? What are you not telling me?" "The All-father has ordered Loki's execution" Scarlett stood up looking furious. "He did WHAT!?" She looked up at the ceiling "Heimdall! Open the Bifrost!" The Bifrost opened around her leaving behind some very confused Avengers.
