Our friends across the Atlantic have treated us to the following series of Heroes spoilers.

Turns out that journalists at BBC Two's Autumn launch enjoyed a world exclusive, never-seen-before, YouTube preview of Heroes season three. Here's a look at what they saw:

• Nathan Petrelli is supposedly dead. We see him rushed to hospital, where resuscitation attempts fail. "There was nothing we could do," a doctor tells the family.

• Elle will be spending a bit of time sparring with Sylar this season.

• Angela Petrelli introduces us to "Level 5", a housing place for the most dangerous criminals in the world.

• Matt Parkman is alone in the middle of a desert screaming for help.

• Linderman is back with a prophecy of doom: "The second coming is at hand," he warns.

• A big bald man, incarcerated in Level 5, shouts: "I'm not who you think I am. I'm Peter Petrelli..."
