Loki starts teaching at Xavier's school
I'm looking for a story where Loki is sent to Charles Xavier's school so that the Professor can try and heal his mind after Thanos' control of him. After some time and a lot of friction Loki improves and starts teaching classes. After and attack by Stryker's forces and an out in the press about the mutant menace Thor assumes the worse and comes to the school in attack mode, demanding his brother to take him home in chains. A lot of Loki's progress is knocked back but he is heartened when the students stand up for him and defend him to his angry (and misinformed) brother.
