I don't think it's patently obvious that RS is playing into any arrangement - he was relatively unknown until people here noticed what he was saying about the finale this year and started spreading the hot embers that started this wildfire!

Back on January 27 though, when he first announced that he knew something, he definitely was not mainstream. Still isn't, actually, but now that US Weekly and Access Hollywood have picked up the story, that's still not enough for you?
Also, I'm curious what you include as the "RS script" when you say that the ending will not take that route? As far as I'm concerned, it's Jason picks Melissa as F1, Jason dumps Melissa at the ATFR 1 and they show that he and Molly are now dating. I think the rest is quite clearly conjecture but much more believable than all these concocted stories about why Melissa's parents don't support her (and after the preview clip of her calling her parents in NZ, I'm not sure how people still stake their life on this theory) or someone is pregnant or something else caused Jason to change his mind. So which part are you so sure will NOT be part of the finale Monday and Tuesday nights?
I think it's a little paradoxical for one to say that the RS theory of this being planned from the get-go is wild conspiracy theory and makes no sense, but yet be willing to say that RS is an ABC plant just set up to drive ratings and hype through the roof. Isn't that still conspiracy theory??
