John would have been a great twist instead of the half brother.

I ended up skimming the later seasons, especially when they brought in even more alternate universe stuff so missed the return of Day and various others. From what I remember the actual finale suffered from covid restrictions severely hindering how many people the production could get in one place so the actual final scene ended up only being the brothers with the previous scene of Dean of and Bobby. Almost every scene was only two people so the plan to bring back various others went out the window.
