Headscratchers / Final Fantasy VII: Advent Children

• At one point, Kadaj summons something with a Green Materia. Summons come from Red Materia.
  • Probably just an animation oversight.
• Yazoo is seen taking the kids in Edge into a truck, and shown driving them away, eventually ending up in the Forgotten City. How did he manage to drive there? The Forgotten City is on a separate continent. Furthermore, how was Cloud able to follow him on his motorcycle?
  • Probably just took a ship that carries vehicles.
• How did Sephiroth come Back from the Dead, anyway? Maybe I missed something because I didn't see Complete, but it didn't make any sense to me.
  • It's basically explained in On the Way to a Smile - Case of Lifestream: Black. Basically, Sephiroth obsessively thought of Cloud, to keep himself alive in the Lifestream and used the three white-haired guys as a way to come back, along with Cloud's memories of Sephiroth. Aerith could do the same thing, but she chose not to.
    • The Remnants were made of Jenova cells but weren't powerful enough to create a body for Sephiroth to house. Being exposed to a pure Jenova sample, the "Head", it let Kadaj's body act as a new one for Sephiroth's mind to leave the Lifestream.
• One question gets raised, thanks to the existence of Dirge of Cerberus - how the hell does anyone have the ability to call each other? Maybe the plot point wasn't written yet by the time Advent Children was made, but a story element of Dirge involved the start of the game having a celebration about the restoration of the Worldwide Network, or the Internet for short. Granted, phones existed before the Internet, but with the collapse of Shin-Ra, the management of phone networks are never once brought up either. Maybe they're so important that they're the first thing society restored in just two years?
  • Actually they would be one of the most important things. Why? Because they allow for Instantaneous Communications over a vast distance. Which is great when you are trying to organize and rebuild.
