Can't believe the Breaking Bad universe finally comes to an end tonight. Gonna miss this show so much.
Prediction: Saul "dies." Not literally, but that part of him (and Gene) dies tonight. He goes on the run again now that Marion has blown his cover. He tries calling the vacuum guy (RIP Robert Forster) but for whatever reason that doesn't work out (either he doesnt have the money or other circumstances like a car wreck screw it up). Kim meets with Albuquerque DA and offers to testify against him for nothing in return. Nationwide manhunt ensues, just like Walter.
Eventually Jimmy gets cornered and can no longer escape. Gets arrested, accepts his fate, but keeps quiet. Goes back to ABQ, gets tried in the same courtroom where he represented those teenagers at the beginning of the show. Kim testifies against him, and other lawyers from HHM are present in the galley. Maybe even a BB character makes an appearance (Skyler?). He gets convicted. Has one last talk with Kim before getting sentenced and it's cordial and is good closure for the characters. In this moment he is truly Jimmy and his good heart shows and he has remorse for his wrongdoing. Saul Gone.
Huell is still sitting in that room where Hank left him.
