In my head canon, the final episode is set today, in 2023. Midge and Susy are in their 90s and reconciled. And they’re on tour together, like George Burns. In the final scene, Susy goes into Midge’s bedroom in a hotel suite to find Midge died peacefully, in her sleep, fully made up and dressed, lying in bed with her will and funeral instructions under the pillow. Then cut to flashback to the Gaslight Club.
