Curiouser and curiouser! So, this mystery kid is actually a demon? Or something similar? And if he's got Ed's arm and leg, might there be someone out there with Al's body? That wouldn't bode too well for Al.
The fact that the kid could transmute his own body with inanimate objects must be making Ed wild with curiosity. If it's just because the kid is a demon, then Ed might be out of luck.
Say, what if Al got his body back at the end of the series, but by then he was 15 or 16 and the body was the same 10 (11?) year old one that he lost. That would be troubling and weird. But it would also be weird to get back a body that had grown up without you. It might have changed quite a lot. (Maybe a few tattoos and piercings... *g*)
Episode 28 showed us a lot about where Ed and Al came from, the lesson they learned but failed to actually absorb about being part of the flow of life. So, my question is this:
Is Ed's journey to learn to accept this truth or to fight against it? Often, the hero's job is to fight against the accepted wisdom. But here I'm not sure. And alchemy seems such a flawed gift. Will he have to give up using it at all?
(BTW, this is not a request to learn spoilers! I am spoiler free; I don't even watch the previews of the next episode.)
