“I’m going to hurt you.”

The words were delivered in a calm tone, causing Xander Harris to look up from the book of alchemy he was going through with Edward and Alphonse Elric, and all three teenage boys blinked innocently at the sight before them. Standing just inside the doorway was Colonel Roy Mustang, his hair slightly mussed from sleep, but instead of the neat blue uniform he normally wore, he was wearing a frilly blue blouse and a short skirt with silk stockings and high heeled shoes.

A slight snicker slipped out of Ed before he could contain it, and he ducked his head, golden eyes returning to the book as he hid behind his blond bangs. His brother simply cocked his head in innocent confusion that only Alphonse could pull off with his own golden eyes and slightly lighter blond hair that was pulled back in a waist length braid like Ed’s.

“But Colonel Mustang, how is Xander suppose to learn alchemy if he doesn’t practice?” Al asked, and Roy turned, stomping out of the room as he muttered about teenage prodigies and their bored students.

Ed, Al and Xander smirked at each other, passing around high fives for a prank well played.
