8. Saul Goodman's Ex-Wives
Not much is known about Saul Goodman's past. With the fact that this show will lean far more into the realm of comedy than Breaking Bad, a few awkward appearances by Saul's ex-wives could make for some great comedy. It would also be a great way to get to know more about TV's favorite lawyer.
7. Hank Schrader
The fact that Saul represents the worst of the worst bodes well for the possible interactions with Albuquerque's finest. With the meth trade being one of the most popular business in town, there's no doubt Saul would have several run-ins with the DEA. It would make a ton of sense, at least to me, if we saw a blast from the past with Mr. Hank Schrader on a number of occasions.
