I don’t understand why Seele would go to such great lengths to kidnap Fuyutsuki when he probably would have come if they just asked him.
Probably so that Gendo doesn't know about it. After all, they're pretty much telling Fuyutsuki to spy on Gendo. Though as we can see, Gendo knows everything...
Well, onto the meat of the story, the grand flashback. So far the manga hasn't hesitated to add in stuff, with a good degree of success as well. I'm intrigued to see if there's something more than what was on the anime.
