Seriously, what do some people think with?
1) Look. If it wasn't perfume, then why would Hoenheim tell Dante that he couldn't miss the perfume's scent? ^^
And Ross talked about his "delicate perfume". I somehow find it hard to believe that rotten flesh smells delicate.
2) Hoenheim MUST have created Envy. Proof:
Envy and Greed knew eachother before Greed was sealed. They are about the same age, that is. (As are Dante (Greed's creator) and Hoenheim.)
Envy said "I can never forgive you, since you carry that bastards blood" to Ed in the Fifth Laboratory. Seems like he's pissed at the one who brought him back, since the blood Ed carries is Hoenheim's.
3) Dante is That Person. Watch the serie's again, or kill yourself. ^^ The Homonculus didn't exactly refer to him as their Master when he entered and kicked some butt, did they?
Nope. Gluttony followed Dante's words and attacked him.
(Plus, they bowed to her in the beginning of ep. 44)
4) I wonder if Dante really had a reason to resurrect Greed (whatever he was called when he was "alive"). Maybe she just used him to be able to use alchemy without a t.circle... Greed got pissed, Greed refuses to follow Dante's orders, bla bla.
Now for a theories.
There are huge differences between the manga and the anime. But in several places, they are the same.
In the Fifth Laboratory (in the manga), Envy and the gang spares Ed's life because That Person had told them to. Something about him being a good sacrifice. They're talking about sacrifices a bunch in the manga. Maybe we will find out about them in the anime to, that Dante plans to make sacrifices to become a God.
In 44, she says that humans cannot become Gods, and glares at Rose's baby. Worthy sacrifice, or something?
I think there is something about that old relgion she talked about... She might be from it?
Please fill me in if there is anything I have missed. ^^ I might have forgotten stuff from the series, and I don't want to sound stupid so. ^^
Haven't read the whole forum either, so I don't know if the things I have mentioned already have been discussed.
