TV THIS WEEK: Terra Nova debuts, a Doctor may die and more!

The biggest premiere of fall, Terra Nova, finally arrives in a two-hour opener. And then it's time to say goodbye to some of the final summer entries, as Doctor Who, Alphas, Haven and Archer sign off until next year.

The other big premiere is BBC America's spirit-infested Bedlam. And a superhero pops up on Castle, Stefan has a run-in with a really old flame on The Vampire Diaries, a mysterious stranger arrives asking questions about The Secret Circle, Finch and Reese look into a dead Person of Interest, that wall in Sam's brain starts tumbling down in Supernatural, and a serial killer brings the Fringe teams together on Fringe.

Here's what we have to look forward to this week on sci-fi, fantasy, paranormal and spy-fi TV.
