I have no idea if this has been posted already or not, because there are so many theories I can't keep up with them all. But I had a weird dream about Alias last night, and it made me think of this. Since we pretty much know for sure now that Vaughn is going to be married, what if it turns out that his wife is a mole? Someone placed inside the CIA to take advantage of his grief for Sydney and marry him, much like Irina was placed there to marry Jack? And if it wasn't revealed until mid-season or later, it would give them time to do some great Syd/Vaughn angst, but it would be easier to resolve than, say, a divorce. If she was a mole, the marriage could be annulled, and Vaughn wouldn't be obliged to feel guilty because he didn't really do anything to break up the marriage. And unlike with Jack and Irina, he wouldn't pine over her because she wasn't really his true love in the first place; Sydney was. She could even have been placed there by Sloane or Irina to distract Vaughn and take him off Sydney's trail. Of course, it more than likely won't happen that way, because they have used that device a lot already, but I like it better than Vaughn's wife being a truly good person that he's going to betray or have cooling feelings for once Syd comes back. That just seems beneath him. What do you think?
