Please I need your help. I try to find a story I've read few month ago. I think on fanfiction net.
It's a loki centric story, but Thor and Odin play also a big part in it, I think.
Its a story where Loki is in the dungeons after avengers. And there are flashbacks.
In the flashback kid Loki and teen Thor went on a adventure to find a witch or demon, because of story's they 've heard. They were forbidden to go alone therefore they took volstagg with them.
Later in the flashbacks kid Loki was punished with housearest and startet a hunger strike. I think he rembembers this while he is in the Dungeons.
Sorry for the shitty English -.-
