At Avengers Tower. Takes place after Thor 2.
...
Chapter Forty
"I call this meeting of the Avengers to order!" Director Nick Fury said. They sat at a big round table. Everyone was there, as Thor was no longer in Asgard.
"Now, I'd normally give a project like this to a team of mine, but I want you guys on the case," Fury said. "There is a girl who keeps messing with me, and she obviously has some kind of power, as she can choose who sees her and she keeps appearing and disappearing." Jarvis projected an image of a girl, about fifteen or sixteen, who had long, curly brown hair and a mischievous smile on her face.
"I know that girl!" Tony exclaimed. "She keeps breaking into my house!"
"She gave me comfort when I had none," Steve said quietly.
"She helped me control my anger," Bruce said, a curious look on his face.
"She helped me make a decision," Clint said. "To save Natasha's life."
Natasha looked at Clint surprised. "She's the reason I said yes when you offered me a chance to live."
"How come everyone gets something cool and life-changing when all I get is a little breaking and entering?" Tony grumbled.
He was ignored and everyone looked at Thor, the only one yet to tell how he knew the girl.
But Thor merely looked at the picture, and sadly said, "Rissa."
"I've actually been kind of worried," Fury said, "As she seems like a sweet girl and a good person to be on our side. But all of sudden, she stopped showing up."
"That's because she's lost," Thor said, easily explaining what happened as she did in the years before.
What are you doing on Asgard?
'I think I got lost.'
"She's lost in a place where we can never find her."
