One of your favourite characters from Breaking Bad is coming back for Better Call Saul

*Warning! Contains spoiler for Episode 4 of Better Call Saul*

Admission time: we were apprehensive before Better Call Saul hit Netflix. After all, how on earth could any new series possibly live up to the brilliance of Breaking Bad? And how well could a prequel - where you inevitably know where it's headed - focusing on one of the lesser characters, Saul Goodman, really be?

We needn't have worried, as Season One drew us into the world of Slippin' Jimmy, with its slow pace, brilliant acting and beautiful cinematography, setting a standard that's so far flowed effortlessly into Season Two.

And the excitement is going to be ramped up even further with the revelation that a much-loved character from Breaking Bad will be turning up very soon.

Co-creators Peter Gould and Vince Gilligan, together with cast members Bob Odenkirk, Michael McKean, Rhea Seehorn, Patrick Fabian and Michael Mando, were speaking at a fan forum at the Dolby Theatre in Los Angeles where they screened the new episode of Better Call Saul (on Netflix in the UK as of today) and Mark Margolis - aka Hector 'Tio' Salamanca - made an unexpected appearance, in good health and before the stroke that renders him mute and incapacitated.

Gould told the audience, “Right as we were breaking down this episode, we thought, Tuco’s in trouble. Who’s he going to call? Uncle Tio. It made sense for this guy to show up. It had to be organic.”

Even Odenkirk - who doesn't appear in the scene - revealed that he was surprised by the move. “I lose track of how the story plays out,” he said. “That blew my mind – like, I didn’t even know. It reminds me, ‘Remember that show you were in?’”

Gilligan was asked by a fan whether they are shooting scenes with other Breaking Bad cast members, to get them in the can before they age and replied, “It’s an excellent question, but it’s not as easy as it sounds. It’d be hard to think that far ahead. We get a lot of credit for thinking like Bobby Fischer and thinking 20 moves ahead, but we really don’t.”

He added that they were trying not to rely on cameos from old characters too much.  “It’s difficult not to overdo it,” said Gilligan. “We love all these characters and actors from the Breaking Bad universe. The difficulty is maintaining a level of self discipline to stop yourself from saying, ‘Lets have this person walk through the background,’ or, ‘Let’s have this person get splashed by mud as Jimmy drives by.’ ”

However, Gould revealed that, “There was a whole, lovely sequence we shot in Season One and didn’t end up using. You’ll see it on the show in a couple of weeks.”

Intriguingly, Gilligan added, “We had an idea for the final episode of Season Two, which was a perfect opportunity for a cameo which we didn’t wind up doing. It was an organic and logical possibility for a particular someone to show up, but we didn’t do and actually I got talked out of it. I’m glad I got talked out of it, because it would have distracted from a very important thing we were doing in that moment.”

Gould agreed, saying: “It killed me though. It would have been so great.”

Who could it have been? It was Walter wasn't it. We bet it was Walter. BUT WE'LL NEVER KNOW.
