I hadn’t actually thought about how Hohenheim recognized Ed, but you’re right that it’s weird. I’d like to think Pinako has more recent pictures of him, though, so maybe he’d seen those first?

I went back to make sure and it shows (ep. 20 at 7:20) every picture with Ed and Al are as small children.

– So either he saw Ed, deemed that since he’s the only angry blonde boy he’s seen since he got here it must be Edward,

– Went around being a bitch towards every blonde teen male he’s seen figuring one of them’s gotta end up being Edward,

– Or he’s just a creep with a lucky guess
