Duh...gee boss now im really confused: -

1) first of all raistlin stop talkin to people that aint there, it gettin worryin, there aint noone with the initials TC

2) jenova is weaker than sephiroth. he managed to cut off her head (altho she mightnt have been able to put up a fight) and hes much harder than her in fights. also he does posses the power to change his form whenever he like hence why you gotta fight him three times at the end.

3) whoever said sephiroth got all his informaton from dodgy/halftruth reports. thats a bloody good point.

4) jenova had no way of comunicating with sephiroth she was never awake/concious when near him. she was always out cold beit from chemicals or mako but whatever.

5) also kinda pointless and probabally wrong but has anyone thought that maybe she was so weak because the lifestream was slowly killing her while she was frozen in it for several thousand years. which is what happened to the clones (the mako in them destoyed thejenova cells leadin to their mentalness) (that was said in a thread a while ago youll have to check it yourself i cant find it.)
