In episode 3, Roy told Pinako that the military had been searching for Hohenheim for a long time. But what was Hohenheim's connection to the military?
When I'd just started watching the series I though maybe he had been a State Alchemist (partly because Ed and Al's mom was watching the wounded soldiers through the window) who'd gone AWOL or MIA, but I somehow doubt that now.
So why would the military be looking for him?
I have some of my own theories, but what do you guys think?
