Paul Merchant manages to do the impossible. He destroys Pinhead. For good.
Paul: Welcome to oblivion.
Not only that, Paul actually manages to confuse and fool Pinhead by revealing the "Paul" that Pinhead was talking to was a hologram while the real Paul was on the escaping ship. Even if just for a slight moment, just the sight of Pinhead looking to the side a bit, wondering what just happened is awesome on it's own.
