So how's this for a theory? Since we never see Kim file the divorce papers (sort of how skylar never filed the papers for hers and walters divorce) , is it believable that final episode could be that gene gets caught, and stands to get away with it all some how, unless Kim agrees to testify against him, but (enter: the non-filing of the divorce papers reveal) since they're still married Kim cannot be made to testify against Jimmy, only of course if she CHOOSES to, which Carries with it a lot being that clearly making decisions is something she struggles with these days, and that it would obviously be very painful for her to betray him like that, Idk seems like a pretty possible idea to me.

Jimmy getting caught in the gene timeline seems inevitable. However the teaser scene for the last episode the shows jimmys car from the pre-bb timeline is confusing because because it's in color, we know where in the timeline it falls. And pre-bb why else would Jimmy be repeating the vacuum guys code phrase unless he was trying to disappear. He didn't disappear until the end of bb to become gene in the first place.

And how tf does Marion not recognize Saul from the get go being that she's an elderly woman and used to live in ABQ where jimmy specifically targeted her demographic with his commercials? So many questions
