I am searching for a relationship-free from what i remember, and also just one chapter long. It was an Avengers fic were Loki gets fed up and tells Thor he do not see him as his brother, and Thor finally just gives up and starts ignoring Loki, walking away from him after battles. Loki then starts attacking the city without any real strategy, and i am sure it ends with Loki sneaking into Thors room it Avengers tower, holding a knife of ice to his throath and admitting he misses Thor caring. It all ended with Tony and Bruce arriving to the room, and Loki telling Thor that he would try redemption for his brothers sake. It was not a slash story, but a cute story of brothers. If that rings any bells with someone i would be most grateful for a link or a name!
