The episode begins with Thelma and the deacon commemorating the fact that it would've been his 35th anniversary to her mother. It is 1988. We can assume that in Thelma's fantasy, she and Reuben are married as soon as possible, probably still 1988 (although they don't actually get married until 1990). The second fantasy is twelve years later, and that would be 2000. Then, it is stated that the third dream scene occurs in 2023, which would be 35 years into the future from when Thelma and the deacon began to look at the old photos and reminisce.
