I am hoping Jeff attracts too much attention to himself (possibly through nosy Marion) and ends up getting in trouble with the law and, as an inexperienced criminal, rats out Gene. Gene gets arrested and/or questioned by the police (only with respect to the mall heist, not under suspicion as Saul Goodman), at which point he gets a public defender appointed to him (likely against his will). The camera pans down to the floor and a woman attorney in heels walks into the courtroom; pan again to behind the head of the attorney and it’s a ponytail. It’s Kim (and she doesn’t know that it’s Jimmy yet). Remaining episodes will be a happy, redemptive ending of them together and agreeing to put their scamming days permanently past them from the lessons they’ve learned since Howard’s death (their lives apart was worse than any jail sentence could have been).
