There's been a rumor going around that Olivia is going to die in the season finale. I believe this is true but I also believe there'll be a major twist to it and this is what I think the twist is going to be: just when you think Olivia is dead and buried for good, she suddenly comes back to life but as a stronger person who has more of an open access to her powers than she ever had before. So something like Jean Grey coming back from the dead as Dark Phoenix. Season three would delve into the mystery of Olivia's resurrection and its consequences on her life. Will she go back to working as a FBI agent or will the change in her affect her status in the Fringe team? Will she be considered a threat or a useable asset? How does Olivia's resurrection affect her relationships with Peter, Walter, Astrid, and Broyles? How will Olivia's sister and niece react to her rise from the dead?
I also have this suspicion that Astrid is one of the First People or an operative of the First People, working in secret and keeping an eye on the goings on of Fringe Prime. It would be a whooper of a bombshell that Sam Weiss is really Astrid in another form if she's a shapeshifter, similiar to but somewhat different from the shapeshifters working for Walternate.
