"Better Call Saul" is set to return for a third season, and as the series delves deeper into Jimmy McGill's past, fans are expecting some story arcs to intersect with that of "Breaking Bad."

"Better Call Saul" might be a spin-off, but it's clearly very different from "Breaking Bad." And since the series shares a universe with Walter White, it seems inevitable that characters from the original show would be making an appearance.

This is certainly implied by star Rhea Seehorn, who plays Kim Wexler in the series. In an interview with Deadline, the actress says she assumes that "it's also on the table for them to do scenes that happen during 'Breaking Bad' years in some fashion." How the writers will go about doing this remains to be seen, but as Seehorn says, they certainly have "a lot of leeway with where they could go."

One thing that season 3 will undoubtedly go with is the volatile sibling dynamic between Jimmy (Bob Odenkirk) and his brother, Chuck (Michael McKean). In the last episode of season 2, the usually straightforward Chuck deviously tricked his brother into admitting that he tampered with the Mesa Verde documents. Will the fallout from this be what pushes Jimmy to finally become Saul Goodman?

Fans are undoubtedly looking forward to that day, which might be coming closer. There have been reports that "Breaking Bad" stars like Jesse Pinkman (Aaron Paul), Gus Fring (Giancarlo Esposito), and Marie Schrader (Betsey Brandt) are set to make cameos in season 3. And if fans are really lucky, they might even see Bryan Cranston reprise his role as Walter White.

The actor recently admitted on "The Rich Eisen" show that he was more than willing to appear on "Better Call Saul." Cranston was so down for it that he says the showrunners wouldn't even have to pitch anything to him. Aside from a cameo, there's also a possibiltiy that the "Trumbo" star will direct an episode.

"Better Call Saul" season 3 is set to return to AMC in 2017.
