As soon as Ed walked through that door, he knew he was making a mistake. He felt the back of his neck prickle, and he had a foreboding feeling in his gut, but he pressed forward anyways.

Strike one.

Hughes was walking past the door as Ed walked in, and he gave a single glance at Ed before bursting into snickers and continuing on his way. Ed was confused, but didn't ask Hughes about it.

Strike two.

He walked straight to Roy's office, trying his best to ignore the strange glances and occasional giggles. He felt his eye twitch when he heard a few whispers, and he caught his name in the mix. But he still didn't stop and barged into Roy's office, kicking the door open loudly.

Strike three. Boom, you're out.

He was yanked to the side by an unseen force, his automail arm crashing into the wall and sticking there.

"What the-!" He tried to pry his arm off the wall, but some weird force was pinning his arm there, not allowing him to move. Mustang was sitting at his desk, looking amused with his hands folded in front of his face. "What the Hell is happening?" Ed shouted, planting his feet on the wall and continuing to struggle. Roy simply shrugged. Suddenly, his arm slid up on the wall, making him yelp in shock and slamming his cheek on the wall painfully. Even Roy winced at the resulting 'thud'. But while Ed's face was pressed against the wall, he caught soft voices on the other side. Something about a magnet...

"YOU BASTARDS! JUST WAIT 'TIL I GET OVER THERE!" Ed screeched through the wall, and he heard someone curse when they realized they were found out. There were multiple footsteps, and Ed assumed they were running away from the scene of the prank. Leaving Ed stuck to the wall by magnetic force.

"I always wondered if your automail was magnetic," Roy said smugly, signing some document or another. Ed merely pointed his middle finger at the Colonel, trying to dislodge his arm from the wall.

"That's it," he breathed, slapping his flesh hand into his frozen automail one. He slammed his hand on the wall, and a section of it folded in on itself, right beneath his arm. The red, horseshoe-shaped magnet flew through the hole, sticking to Ed's arm with a 'clang'. Ed slowly Transmuted the wall back to normal, then turned to Roy with a neutral expression. His bangs hid his eyes as he approached the desk. Slowly.

"So, that was funny to you?" he said quietly. Roy glanced up, not missing the anger in Ed's voice.

"It was a little amusing," he agreed, smirking. Ed suddenly slammed his hands on the desk, sending papers flying and causing Roy to jump. The youngest State Alchemist slowly looked up, his lips turning up in a creepy smile. His eyes were filled to the brim with rage.

"Then I hope you find this amusing as well," he said sadistically, clapping his hands and slamming them onto Roy's papers.

The ink that stained Roy's clothes that day would never quite be washed out completely.

As Ed stepped out of the room, he caught sight of Hughes flapping his hands frantically, his back towards Ed, talking in hushed voices with Havoc. He slipped closer without being noticed, listening to their conversation.

"Listen, once Ed comes out of there and sees us, were dead. Just get out of here while you still can," Hughes pleaded. Havoc shook his head.

"Sorry, but if Chief brings you down, I'm going down with you. I'm with you to the end," he said solemnly, putting his hand on Hughes' shoulder. Ed chose then to be a good time to show himself.

"Hello." He grinned at them, not bothering to hide his anger.

"You're on your own!" Havoc suddenly blurted, turning tail and dashing out of the room.

"Hey! What about going down with - AAAAAAAAAGHHHHH!"

And that was the day Hughes learned to never, ever put a magnet near the Fullmetal Alchemist.

And the rest of the gang saw things that would give them nightmares for the rest of their lives.

I don't know where this came from... I guess it was when I started wondering if Ed's arm was magnetic or not. Then this just... happened. I don't even know... I wrote this at 2:00 in the morning, so it may have a few mistakes. Please forgive me if there is.
