TSCC Fans...

I hate to admit this it but I don't understand exactly wtf happened at the end of that season finale. Ok I get that John Conner jumped into the future with Weaver and Derick did not recognize him, meaning that what they did must have changed the future somehow. But that still leaves a lot of questions about Weaver and John Henry and that female voice saying "I Love you" at the end. Why did Sarah back out of the time bubble? Why did John not back out of it? What was the deal with that metal snake-like robot that absorbed Weaver or was absorbed by Weaver? I could go on...

I watched that part about the metal snake thing again, I think it was just a piece of her that had fell off, you know, like was injured or something. But yeah, about the other parts, there are a lot of unanswered questions. I'm worried this may be the "wrap-up" and we aren't going to get a 3rd season, I hope I'm wrong though. I'm checking online everywhere to see if they are canceling the show since T4 will be out soon, or if they are going a different direction (which would be awesome)... But yeah, not sure either....
