The Neil Gaiman penned episode is now Nightmare in Silver. It was previously known as The Last Cyberman. All the other episode titles are already known, except the finale, which is still being kept a secret.
i can see why he is mad, i agree maybe people shouldn't post BIG spoilers like the big twists at the end of an episode.BUT some people like being spoiled because it just makes them EVEN 더 많이 EXCITED TO SEE THE EPISODE, hence he gets 더 많이 viewers!
