Interestingly, Bob Odenkirk refers to the loss of Chuck as one of the two pillars that will have to fall away before Jimmy becomes Saul.
Breaking Bad only ran for five seasons; could Saul run for even fewer?
Given what happened to Chuck in the Season 3 finale, Odenkirk’s comments could point to the series not lasting for all that much longer.
Granted, the show hasn’t even been officially renewed for Season 4 yet, and it’s hard to imagine that AMC would give this particular show the axe until the creative team is ready to call it quits.
