Jenova, how intriguing

[morecowbell]

Can someone just clear up once and for all where Jenova actually is, and what is her/its status during the game?

the main body is what you're chasing through the game. her status is Sephiroths avatar.

What kind of throws me is that Jenova never sucessfully reunites.

shes not trying to. Sephiroth is in complete control.

I'm also not sure about the relationship between the Reunion and Summoning Meteor.

there really isn't one, Sephiroth is calling the clones specifically (SPOILER) Cloud to give him the black materia
