With the Breaking Bad spinoff Better Call Saul set to be a prequel, series creator Vince Gilligan admits that “the sky’s the limit” for character returns.

In a new cover story by The Hollywood Reporter, Gilligan openly admits that any and all characters from his beloved meth drama which wrapped in late September could make a return.

“The sky’s the limit with a prequel,” he says. “‘Better Call Saul’ will exist in the time before Saul met Walter White, so in that time everybody who’s now deceased in the ‘Breaking Bad’ world is obviously alive. You never know who might turn up, when or where. We haven’t nailed it down yet exactly what shape the story will take. I could definitely see a version of this where Mike Ehrmantraut is an important part of the series.”

The biggest takeaway from these new comments is Gilligan suggesting that Gus’ former hit man may make a return. Mike was a favorite on Breaking Bad and played an increasingly important role to Walter White before being killed off in the first half of season 5. Gilligan is likely playing coy because the series hasn’t been fleshed out and no deals with actor Jonathan Banks have been struck yet.

In a separate article also published on THR today, the showrunner says that Aaron Paul (who played Jesse) and Bryan Cranston (Walt) are interested in appearing in the prequel as well.

Banks’ return to the series would help bridge the gap between Breaking Bad and Better Call Saul, making it easier to bring viewers over to the new show.

Though he didn’t specifically cite Gus in this new interview, we wouldn’t be surprised if Walt’s former meth boss makes a return as well. Actor Giancarlo Esposito spoke recently about a potential comeback for the spinoff and said he’d “jump at the opportunity.”

Elsewhere in his THR profile, Gilligan says that one of the main reasons he’s excited for Better Call Saul is that he’ll be able to work with the Albuquerque, New Mexico crew again.
