Ultimecia and Squall's parents musings

[LunarWeaver]

Sorry if this has been brought up before! And don't read this if you haven't beat it, but I think the spoiler warning has officially expired.

Why does Ultimecia do all she does? Why is she compressing time and hating on everyone? Does she somehow remember seeing herself defeated by Squall because it's in Edea's memory, so she's trying to kill SeeD before they kill her, not knowing that's why they kill her in the first place? But nothing is ever mentioned of sorceress's memories being passed on from on to the other, nor would she have any reason to possess Edea in the first place without any knowledge of what's going on...Time travel stuff hurts my head haha! Maybe I should just accept she's evil because she's like that and let it be.

Also, are Laguna and Raine squall's parents? I base this only off they never really tell you much about his 'rents, he had to get that ring from someone and Laguna gives a ring to Raine in the end, and the fact Raine looks like Squall's female twin in CG style. Does she have a baby that gets taken to the orphanage when Ellone does? That would leave an awful lot unexplained though...But Laguna could have got her pregnant without ever knowing it and then left before she knew it herself I guess. Or maybe not, it's been a while since I played this sucker and I forget all the story details... So why I'm thinking of all this now is beyond me.

Oh no, I've become one of those fans that reads everything from nothing and makes up theories!
