Well, we all know that she controls the mind of the real Sephiroth, who is controlling the mind of the Sephiroth clone(s). 'Jenova Reunion' is said quite a few times in the Advent Children trailers. Do you think it means that Jenova is using her mind-control to reunite all of the mutated humans (as in trying to get her cells back because the ShinRa seperated them and put them into the humans) and the Sephy clone(s) and all that? I don't know, I haven't even played the game but I've researched. In the trailers you'll see the picture of these scaley-creatures...dragons and stuff. They must be either the mutated humans that escaped from their pods or the Planet is sending off the things called WEAPONs because Jenova is coming back to life from the Northern Crater and the Lifestream and she needs to be stopped? Because in the game it said that the Planet sent off the WEAPONs to kill Jenova, but it found that they did not need to anymore since the Cetra sealed her away. So the creatures lay dormant in various parts of the world. Now, maybe they're coming back? I'm not sure, you give me your oppinion.
