Aside from the three evident clues, i knew vaughn was alive for sure when he told Syd "We'll find each other. We always do." in Sydney's dream sequence on the beach at the end of episode 10. I love foreshadowing and repeated one-liners like that. But how about guesss for the end of the season? I suspect the old Rambaldi prophecies wil come back into play with Syd's baby. Like back a while ago when they were trying to artificially use her eggs to make a child after her two year amnesia. I'm guessing the writers will bring back Rambaldi, reveal the final endgame and felgercarb, mess around with past characters, like Will, Anna, (and Francie? I heard rumors. any scoop?), and finally end the show with Syd and Vaughn retired from the CIA in Santa Barbara with their baby. I bet Jack, Irina, or both will die, possibly in order to save someone's life. And lastly, Sloane will finally get what he's got coming, however, knowing Alias, series finale or not, they will leave us with a clifhanger. Hopefully not something cheesy like a supposedly dead Sloane's hand trembling, but lately mt expectations for originality have dissipated. Still, gotta love the show for all it's worth.
