Jenova reaching into the world was the Geostigma, and when Kadaj and Co got near them their power amplified, a perfect example is when Kadaj is at Rufus' place and he starts flipping out and you see a glimpse of Seph. By bringing everybody with the geostigma together they were able to have more power, and easily manipulate them(The kids) to their will. Aeris helped in the background, you could tell when Voz or whoever was distracted when he got near the flowers in the church. After Kadaj got Jenova's head which was essentially the Geostigma concentrated, he became Seph, and then the final battle occured again, after Cloud beat him, Kadaj returend to normal, and Seph went back into the lifestream. That's bout all I can think of now, but it's not like it was a shitty story.
