Kate Austen – Traitor
Kate Austen: fugitive on the run turned loving mother of someone elses child. Something just doesn’t add up there.
I propose that Kate has some hidden agenda, something deceiptful and traitorous that only she knows what she’s up to. Not even Ben could have manipulated her to this level.
When the O6 go back to the island I think she will give Aaron back to Claire, demanding no furthur part in his upbringing. Then, she will turn her back on Jack and co. to do something for herself.
Maybe she has a secret alliance with Christian or Jacob, or even Locke, and that her mission was always to end up back on the island to serve some purpose. Some mean and evil purpose.
Just what that purpose is is another mystery, but you can rest assured that Kate is up to something.
