Is Vaughn married, maybe it was an engagment ring. How could Vaughn leave her so quickly, only two-years and get married? HOw the hell did Will survive that stabbing? Maybe Syd was brainwashed and had forgotten where she was the past two-years, or i think she could have been captured by Sloane, brainwashed to forget who she was, then when they were done with her, they unbrainwashed her... interesting eh? That was an amazing episode, so many unanswered questions, i am dying for next season, way to go J. J. you never cease to amaze me.
