Better Call Saul: 10 Breaking Bad Cameos That May Yet Pop Up
2. Skinny Pete and Badger Mayhew
Skinny Pete and Badger may finish the Breaking Bad series as the most morally innocent characters of all. Aside from some methamphetamine dealings, Jesse's friends were pretty harmless and were somehow always presented as well-meaning and friendly. The viewers definitely took a shine to them, and they are probably the most likely side characters to get involved in the Better Call Saul story.
Skinny Pete had spent time in jail with Tuco Salamanca before Breaking Bad began and it's possible his tenure in jail occurs during Better Call Saul, so if he was to make a reappearance it probably wouldn't be until the final season. The Left 4 Dead enthusiast struggles with a methamphetamine addiction and as Nacho Varga's story gets involved in that side of the city, characters like Pete may resurface.
Badger, on the other hand, is the client that Saul himself represents in his debut episode. If we do come full circle by the end of the spin-off then Badger cropping up is an almost certainty.
