I'm going to try looking at this a different way--I mean, it's how I've looked at it, but... well, stay with me here.
From twiztv.com:
ANGEL
It wasn't just her ascension. Everything that's happened to Cordy in the past few years"”all of it"”was planned.
SKIP
You really think it stops with her, amigo? You have any concept of how many lines have to intersect in order for a thing like this to play out? How many events have to be nudged in just the right direction? (looks at Lorne) Leaving Pylea. (looks at Gunn) Your sister. (looks at Fred) Opening the wrong book. (looks at Wesley) Sleeping with the enemy. (beat) Gosh, (chuckles) I love a story with scope.
Skip could have just taken notice of those things, and used that as "evidence" to manipulate Angel and co into believing this "ruse". To make them
think that they have no choice, that they can't stop what's going on since it's "predestined". I mean, what does leaving Pylea have to do with it? Or Gunn's sister, or Wesley and Lilah's sexy sex making? He's just spouting out things that happened, implying that they had some larger meaning... I don't think they do, I think Skip is full of shit.
GUNN
No way. We make our own choices.
SKIP
Yeah, sure. Cheese sandwich here, uh, when to floss. But the big stuff, like two vampires squeezing out a kid?
ANGEL
Connor.
WESLEY
An impossible birth to make one possible.
SKIP
That's what the kid was designed for.
LORNE
(chuckles) To sleep with mother love?
ANGEL
To create a vessel.
Why go through all that trouble? If they're demons with big demony strength and powers, couldn't they have found another way to give birth to Jasmine? It'd make more sense to me that the PTB "made" Connor to give Angel a chance at redemption--if Angel has a human son, maybe he'll have something worth fighting for. Again, couldn't Skip just be using this to manipulate the gang in a pathetic attempt to make them give up all hope of getting rid of Jasmine?
And anyway, if Jasmine followers really went through all the trouble to let Connor be born, why send him to Quor'toth? Does he really need to be a crazy fighter guy in order to make sex with Cordy?
"Oh, well, no; actually it's because a baby can't impregnate a woman, and Jasmine HAD to return in 2003 or whatever year it was". If that's the case, why not just 'manipulate' things back in 1985? Why not get Angel to vamp-regnate someone then, so that Angel Jr. would sleep with Cordelia after having grown up on Earth for 18 years?
I've watched this one a few times, and although I'm not a huge Jasmine fan, I never thought "this ruins Angel!!!". I never actually sat and thought out all of what I just posted, but in the back of my head somewhere, that's what was going on. I never trust what the bad guys tell me.
