So our speculations were correct. Envy is indeed a child of Hohenhaim, perhaps from one of his lovers, and I assume Hohenheim left him when he was young. Perhaps returned later to find him dying, and made him a homunculus? I don't see any other reason why he'd harbor hatred. I mean, Hohenheim left him to go have other sons with another woman.
I don't understand how they're going to bring Archer back. Don't get me wrong, I'm one of the few who love Archer, but all that will fix him is a fragment of the stone. Did you see? he's still bandaged like a mummy -poor baby. ;_;
OK, so Tucker transmutates Nina, but he had no way of bringing back a soul. I mean, there isn't a soul left to fix, right? Scar took care of that back in the eps, when he turned her inside out. Though perhaps, with more help, he could do it. I'd like to see Nina back.
Because of this, we found out everytime the stone is used, it erodes, thus eroding Al's body because he IS the stone. Now that Ed can't touch him, there's no way to transmutate his armor back to the way it was. Game over.
And if they do make Lust human, it would probably have to be the second to last thing they do. This all depends on how much energy is used. Taking Al's body and afixing his soul will be last for sure because it uses the most energy. Creating a body out from scratch.
All in all, I personally think Envy will be the last homunculi to be defeat. This means that Lust and Pride could POSSIBLY live. I don't see the Fuhrer as completely bad and neither Lust. Wrath might liv too, but I don't know if I see that happening; Sloth dies in the next ep.
But right now, I'm more worried about Roy and Armstrong. Their chances of dying are 50/50 unless someone puts a stop to the troops moving. -__-
I can't believe it, 5 eps left. Of course, then there's the movie :D but I personally think there should be another season. But we can't forget our beloved manga!
