1) Loki is taken back to Asgard by Thor and is not really accepted by the people of the city and is mocked/attacked. He gets hit on the head by a stone and has to be taken to the healers but he doesn't remember the event.
2) Loki has kind of joined the Avengers to fight against Amora. They go to an old warehouse/block of flats and all of the Avengers are hurt but Loki steps in before Amora can kill someone (I think it's Hawkeye she aims for) but he gets injured in the process.
If anyone has any other Loki h/c or angst suggestions I would be delighted to read them. Thank you! :)
