But that's what frightens people so much about the remake mystery. Are they going to integrate Genesis into the story and over-complicate things or are they going to leave the story as it was. As much as the idea of Genesis is quite intriguing, it is something that had no place in the original story.
I agree that the story would get way to complicated if G and Sephy were twins. Mainly because the CC plot pretty much nixes it. Dr. Hollander (Angeal's father) specifically says that Genesis is Angeal's half-brother (sorta) - so to make him Seph's brother would be a little overkill. Hollander says that Gillian (Angeal's mother) was injected with Jenova cells and then her DNA is implanted into Genesis as a fetus. Angeal is Gillian's birth son, so the Jenova cells are a natural part of his genetic make-up. Unfortunately, both Genesis and Angeal suffer from a bit of unnatural deterioration that only Hojo was able to perfect with his experiment with Lucrezia and Seph. Genesis' only relationship with Sephiroth (besides being friends) was that he needed Seph's cells to stop his degeneration. I still haven't researched into the between years of CC and DOC to discover G's ties to Wiess that would explain the ending to DOC.
Also, personally, I think that Seph is a bit of a dead horse when it comes to villains. The only way that I could see him being resurrected is if the unthinkable actually happened: He came back as a good guy (whether it be because Aerith reforms him, he has amnesia, or he is cleansed of his Jenova cells and no longer seeks out her goal of using the planet as a vessel). We need fresh blood for baddies. That being said, I was intending on writing a fanfiction in which Genesis and Sephiroth were, in fact, half-brothers. The only way this would work (believe me, I've spent considerable time trying to find another way), would be if Vincent was actually Sephiroth's father and Hollander got his hands on Vincent's DNA to fertilize Genesis' mother's egg and then injected the fetus with Gillian's DNA. In that case, both Angeal and Sephiroth would be Genesis' half-brother but Angeal would not be related to Sephiroth by blood. Confused yet? Yeah, me too.
