Grace remembered being on the street her home in flames and her last wish being to find her love. Then there was a bright light and she was falling. Grace landed in someone's arms. She just wished she said something other than "Loki," before the world faded.
Tony had this gut feeling all day long that he NEEDED to be on the roof. So Tony was just standing there on the roof in his Iron Man Suit, when a girl came out of nowhere, from the sky, falling towards the ground. Tony was instantly after the girl, who seemed sad, alone and from somewhere else. Tony heard her say one world that made him bring her to the tower.
"Loki."
Once Tony had landed on the roof he carried her down to the lab where Bruce was, Tony didn't think this kid needed a medical team, but at least wanted someone to check on her.
Bruce was exhausted at first he thought Tony was trying to pull a prank until he saw a girl no more than 16. Unconscious. Bruce took her pulse and was about to get a blood sugar level when her eyes flew open she said her name was Grace, she then realized where she was, screamed and ran.
Grace ran until she saw something that she could hide under, a bed she curled up underneath the bed scared, crying and thinking of Loki. As a teen who learned she was adopted she instantly fell in love with Loki. She had discovered she was adopted but that she wasn't 100% human. Not the same as what she was told. Just like Loki.
JARVIS Immedietly informed Bruce and Tony of where Grace was. They tried to get her to come out but Grace would only say "Loki, Loki, I need Loki."
The two geniuses looked at each other and shrugged then Tony made a phone call.
