Hold Me So I'm Not Falling Apart

Thor is in Asgard after the Dark Elves attack, trying to fix everything they destroyed. He sends Loki to Earth instead of back to his cell in Asgard because he redeemed himself and is still mourning their mother's death, with who he had a very deep connection, so Thor thinks that some time away from Asgard will do him good.
Now, the Avengers have to deal with Loki when he says that he wants to go to a high school after discovering how different Earth's and Asgard's educational systems are. Things happen.
