i've always wondered what Rose's baby signified... was it some kind of powerful array? cause it looked like it could summon the gate (at Dante's will?) and if it was something special, what happened to its specialness...?
also, didn't Dante think of transferring into Rose? and then she goes on saying that with her being in Rose's body her dream would be to be coupled together with Ed... that's what i gathered, i think. if that was the case, who was going into Ed's body?
edit: Envy was who's "mistake"? no wait, the answer is Elric Sr. right? it was kinda weird that he could still make "mistakes" when he was able to produce the Stone (and the only one before Ishbal since it seemed Dante couldn't make them and had to trick people into it) unless perhaps "the world (including him) isn't perfect" applies here. he could probably have made Envy before achieving the ultimate (the Philosopher's Stone) too though...
