QUOTE ("Red Shrimp")
what about their quest for Rentanjutsu? You know - the reversed transmutation circle that Al came up with?
Why am I thinking that the ending could be a cliffhanger....
Al didn't come up with it, he just found something that was already done by someone else

Plus the quest for Rentanjutsu, which is something I never believed in, was cut short the day Alphonse proved unable to learn it and May unable to teach it

I think the difference in culture is too high, that kind of stuff comes naturally to a Xingese, but to an Amestrian like Alphonse, I think it's too hard without clearer explanations.

I dunno about that to be honest. Bradley is important, very important, but I think you're forgetting he's only been around for sixty years. The Homunculi have had their plan in action for centuries. I'm not saying Bradley isn't important, probably the most important to the plan of the seven Homunculi, but to argue they need him more than Father is going a tad far in my opinion.
Bradley is certainly the most important of the Homonculus, that's for sure. He was charged to find human sacrifices, finish the circle with some wars, etc. He isn't more important than Father for the plan, but I stay on my position that he is the true main villain of the manga, because Father is too far from the action to be called such.
