A month later, Edward Elric stormed into Colonel Mustang's office, with a fully restored Alphonse Elric trailing behind. He slammed the door shut and glared. But instead of the smug smirk and clean office he was used to, his superior had his head in his hands and every possible spot in the office – except the paperwork – was scorched.
"What the hell?" the blonde alchemist blurted, finally getting Mustang's attention.
"I'm not allowed to burn orders or paperwork so I had to settle for everything else," the older man explained, sulking a little.
"But why burn everything?" Al asked, clearly confused. By way of explanation, Roy just handed Ed the envelope containing his orders.
Major Edward Elric
Fullmetal Alchemist
You, along with Colonel Roy Mustang, are to go undercover for an entire school year at Hogwarts School of Witchcraft and Wizardry to research magic and protect Harry Potter. The two of you are to pose as father and son, as well as a teacher and a student. Alphonse Elric is is not to come on this mission, seeing as he is still recuperating and is not in the military, but he may visit on holidays. Crucial information is enclosed. Do not destroy these orders and don't insult one another. That includes comments on both height and rain. You have three months to prepare and grow accustomed to wizarding ways.
Fuhrer Grumman
Edward could see why Mustang had gone on a rampage; he himself kicked the waste basket with all his might, making Alphonse jump.
"Dammit! Magic! Really?" Ed stated irritably.
"Apparently the headmaster of the school specifically asked for the boy to have body guards. Grumman told me that the man's willing to give us a demonstration of magic once we finish going over your orders," Mustang replied. "I don't like this either, after all, I am an alchemist. I agree that magic shouldn't be possible, but we might as well take the mission."
"Fine," Ed huffed. Then he smirked at his brother's bewildered look. "Well, at least this should be interesting."
"What are you talking about?" Al finally asked, exasperated at not knowing. He gratefully took the orders that Ed handed him so he could understand.
"Good luck on not insulting each other," he grinned when he finished. He knew that the two hot-tempered state alchemists would have a hard time acting like father and son, since they tended to argue. A lot. His not-so-innocent comment caused both Ed and Roy to scowl. "I'll miss you, Brother."
"I'll miss you too, Al," Edward replied with a sad smile.
