Rumors have been flying about the Breaking Bad spin-off for character Saul Goodman (played by Bob Odenkirk).  Now that the deal is moving ahead, the creators are considering making the spin-off a prequel to Breaking Bad.

“Those are the two big questions we ask ourselves — is it a half hour or an hour, is it a prequel or a sequel? But having said that, I have to be coy as to whether it even could be a sequel. Because you never know, when the dust settles at the end of our final eight episodes, where everybody’s gonna be and who’s gonna be left standing. I can’t even say for sure that it could be a sequel. It may be, it may not,” Breaking Bad creator Vince Gilligan said told TheWrap.

The series is not a done deal yet, though it has been discussed since 2012. Huffington Post reports Gilligan is working on the spin-off with Peter Gould, the writer who introduced the character of Goodman to Breaking Bad in Season 2. Earlier this year it was announced that Breaking Bad will being its final season this August with eight new episodes.

“I personally would like to see it happen, because I think it would be its own creation and its own creature, and I think it would exist in a Breaking Bad universe, as it centres on a character that was integral to Breaking Bad, but I think it’s its own thing. It’s like comparing an apple to an orange. Or white meth to blue meth,” Gilligan told Empire.

Breaking Bad returns Sunday, August 11 at 9 p.m. ET on AMC.
