On the final season of the television show This Is Us. Rebecca’s storyline for the first episode of 2022 had her trying to remember a word. She struggled in different scenarios where we knew the word—but it was illusive to her. When she realizes the word is “caboose,” I enjoyed the symbolism that her revelation came at the episode’s end and imagined that all the seasons so far were like five train cars and this season is the caboose bring the series to an end. Maybe This Is Us writers had other reasons for choosing “caboose” but the symbol that it’s bringing Rebecca and the series to the end of the journey works well for me.
