So, I'm downloading some fics to read on a long plane ride tomorrow morning, and I'm trying to find one in particular that has been driving me crazy trying to find!
This is sort of an alternate universe which takes place pre-Thor and Avengers, where Thor and Loki come down to Earth to make diplomatic ties. Thor is not a particularly nice guy in this piece, and looks down on the "backwater Midgardians," expecting his every whim to be catered to. Loki, on the other hand, is quiet and observant, and is puzzled when everyone seems to like him better than Thor! I remember one particular scene where Thor cannot even tell the Captain/Commander/someone-in-charge the name of the ship they have been housed on.
Also, there is a funny group of sailors that sort-of adopt Loki, and they play poker together and Loki is touched that they do something ridiculous to try to bring him dinner or something later that night. Thor seems to be very controlling, and he is decidedly unhappy when he realizes the people seem to prefer his brother to him.
I also remember at the very end, they are under attack from someone, and Loki uses his magic to save a city from an asteroid or something even though SHIELD asked him not to reveal his magic to the general population. When he wakes up in the hospital, he is horrified that he has "ruined the negotiations" and is stunned when SHIELD thanks him and the people call him a hero.
Please, PLEASE help me find this before tomorrow morning. I am desperate!!
Thanks in advance for everybody's help,
