Disclaimer: don't own either one of them, just this meeting.

The plotbunnies are insane. It's the only explanation I can think of.
Oneshot, double drabble.

As per usual, anonymous reviews get answered in my profile.

"You seem to be taking this quite well for someone from a world without alchemy. I'm kinda surprised that you believed me so quickly."

"Let's just say it's not the strangest thing I've encountered recently. Plus a detective works from observation, and your - automail? - is quite convincing."

"A detective? Aren't you a little…young for that?"

"I'll have you know I'm older than I look. Supposed to be quite a bit taller, too – it's a long story. There's nothing wrong with my mind, though, and there is still only one truth."

"Oh, he got you too, huh?"

"What?"

"…nevermind. But you can't tell anyone else about this."

"What am I supposed to say? 'Oh, someone walked out of this elaborate glowing pink circle in midair in my backyard claiming to be trying to find his way back to a different world.' Like anyone would believe that."

"You did."

"I saw it. And I know there's only one truth."

"Yeah, and trust me, you don't want to meet him."

"…you're going to have to explain what you mean by that at some point."

"I won't be able to move on again for a while, so I just might do that…"

Detective Conan, meet the Fullmetal Alchemist. Don't worry, he's just passing through.

Plotbunnies say Ed needs a while to recalibrate, taking into account his relative 'location,' before he can take another dimensional jump. Doesn't look like he minds finally having found someone shorter than he is, though.
