Still basking in the glory of the series finale of “Breaking Bad,” creator Vince Gilligan showed up at the “Colbert Report” last night (September 30).

And during his conversation with Stephen Colbert, Mr. Gilligan revealed that he’ll have a difficult time letting go of Walter, the show’s main character (played by Bryan Cranston).

Vince shared, “You know what? Yeah, my six writers and I spent a lot of time thinking about this guy and he’s a tough guy to have stuck in your head for 24 hours a day, six years straight.”

As for whether or not he cheered for Walt, Gilligan noted, “There were times when it became extremely difficult to root for him because he was kind of a bastard a lot of times.”

“I think the nastiest thing he ever did, it was two episodes ago, it was the moment when Walt said to Jesse with apparent glee, ‘I watched Jane die. She choked to death and I could have saved her and I didn’t.’ I think that was the most sadistic, nasty thing that he did.”
