Ok so well this crazy thought came to me as I was re-reading the manga scans (since I can't get anything new, I figured I'd just reread the old stuff =P)... There are some scenes, some images of Ed that just remind me of Kenshin from the Rurouni Kenshin manga. The way his hair is styled sometimes in Ed's profile (especially in scenes where you don't see his eyes), I just think of Kenshin (during the later books when Nobuhiro Watsuki's art changes drastically in them). Also, when Ed's hair is down, sometimes it reminds of what Kenshin's hair looks like when it's not tied back... Sometimes the style of how the fingers and hands are drawn are somewhat similar to Watsuki-Sensei's art style as well.
Ok, yes, I know I'm weird... and it's probably just me noticing this, but I couldn't help but post this idea with the hopes that I'm not the only insane... =P Again, please don't shoot me for this outrageous, silly post.
