Warning, Fringe fans: the following trailer for this Friday's season four finale has only been approved for those few whom William Bell has chosen. View at your own risk.

Following an incredible opening hour of this Fringe event, the Fox series will wrap up with "Brave New World Part 2," an appropriate title, given the plans a returning Bell has in mind.

"If we are capable of being gods, then it is our destiny to do so," he tells John Noble's confused, angry, desperate Walter in the extended preview below.

Look for resurrection, destruction, creation and... dinosaurs to all be featured on the finale. Get ridiculously excited for it now:

Elsewhere, John Noble and Leonard Nimoy took part this week in a video interview, promoting the upcoming episode and how it plays into the relationship between their characters.

"I can't beat him," Noble says of how Walter views Bell at this point. "He's insane. He's holding all the cards."
