Better Call Saul spoilers follow.

Better Call Saul co-creator Vince Gilligan has admitted to making a mistake in the show's penultimate episode.

In Monday's (August 8) episode of the Breaking Bad spin-off, viewers saw Gene's (Bob Odenkirk) true colours when he considered murdering both an elderly lady and a cancer patient, hinting at the crooked lawyer's demise ahead of the series finale next week.

Though fan's sights are now set on the finale, Gilligan has admitted to messing up a key detail in the script for the latest episode, titled 'Waterworks'.

"In this last episode, which I’m very pleased with and was a group effort like they all are, I realised Gene, at the very end of the final act, he should’ve been talking to Jeff on his Bluetooth earpiece," he revealed during the Television Critics Association virtual press tour (via TVLine).

"Because we had made a point in the previous episode that he was back to being Saul with the earpiece. I dropped the ball on that one when I wrote the episode."

Gilligan admitted he also has some pearly white regret from his time working on Breaking Bad, adding: "Aaron Paul’s teeth were too perfect. This poor guy just got the living shit kicked out of him time and time again, story-wise, and also he smoked a lot of meth, and his teeth were just like Cary Grant perfect."

It seems fans will be bidding farewell to the beloved franchise for good, as, although Gilligan acknowledged that there's scope to do to more, he said that he's ready to move on.

"Yes, I could do more with this universe," he shared with Rolling Stone. "And maybe someday I will, especially if I fail at everything that comes next. Then I'll come crawling back.

"But right now, whether there's more room to grow or not – and there probably is – I feel like it's time to do something new."

Better Call Saul airs on AMC in the US and on Netflix in the UK.
